Resumen

O presente estudo analisa o Boletim Científico da Escola de Chimica Industrial do Pará considerando este documento como uma “inscrição” resultante do encontro entre os produtos naturais amazônicos e os instrumentos dos laboratórios da Escola. Inicialmente são tecidas considerações sobre o papel da Química e daquela instituição de ensino no contexto dos anos 20 do século XX, particularmente em uma cidade (Belém) vivendo a decadência econômica após o fim do chamado ciclo do látex. Em seguida, o Boletim é apresentado, elencando-se sua constituição e características depreendidas a partir da sua exegese. Ao final são tecidas considerações que evidenciam ter sido a Escola de Chimica Industrial do Pará uma instituição cujo perfil está de acordo com o chamado “estatuto da modernidade”, segundo o qual representava à época o papel de intérprete objetivo da natureza, buscava a construção de um conhecimento “positivo” e “verdadeiro” e tencionava, no contexto em que se inseria, contribuir para a redenção econômica da região mediante a aplicação do conhecimento científico visando o “desenvolvimento e o progresso”.

Resumen

Fluoroalkylations have received increasing attention in the academic and industrial environment due to the particular properties of the active ingredients, strongly influenced by fluoroalkyl substituents. The inherent difficulties of introducing a fluoroalkyl substituent into advanced intermediates has triggered the development of an enormous number of specialized reagents, which, however, are often not suitable for large scale applications. In contrast to this reagent based fluoroalkylation approach, the direct activation of industrially readily available fluoroalkyl halides could be more suitable for a large-scale processes. In this way the dithionite initiated fluoroalkylation as well as newly developed catalytic activated fluoroalkylation protocols were considered for industrial large-scale applications.

Resumen

The Internet of Things (IoT) is being deployed in an ever-growing range of applications, from industrial monitoring to smart buildings to wearable devices. Each of these applications has specific computational requirements arising from their networking, system security, and edge analytics functionality. This diversity in requirements motivates the need for adaptable end-devices, which can be re-configured and re-used throughout their lifetime to handle computation-intensive tasks without sacrificing battery lifetime. To tackle this problem, this article presents Chimera, a low-power platform for research and experimentation with reconfigurable hardware for the IoT end-devices. Chimera achieves flexibility and re-usability through an architecture based on a Flash Field Programmable Gate Array (FPGA) with a reconfigurable software stack that enables over-the-air hardware and software evolution at runtime. This adaptability enables low-cost hardware/software upgrades on the end-devices and an increased ability to handle computationally-intensive tasks. This article describes the design of the Chimera hardware platform and software stack, evaluates it through three application scenarios, and reviews the factors that have thus far prevented FPGAs from being utilized in IoT end-devices.

Resumen

This paper discusses the application of the circular economy concept and industrial ecology approach in the context of industrial chemical sites. A real-life case study about the use of bromine as reactant for chemical synthesis and its recycling by Syngenta in Monthey is described in detail. With a recovery yield of 97% it represents a well-established example of closed loop recycling, one aspect of the circular economy. The process leads to significant safety and environmental risk reduction and economic savings in the order of several million CHF per year.

Resumen

In recent years, transition-metal-catalyzed C–H functionalization has emerged as a potentially greener alternative to classic cross-couplings and as a powerful tool to access complex functional molecules with improved step-economy. This short account relates our experience of industrial collaborations in C(sp3)–H bond activation, which were key to the development of this topic in our group. The synthesis of the antianginal drug Ivabradine led us to develop a general approach to benzocyclobutenes, which were further employed in pericyclic reactions. A follow-up study led us to discover a new method to construct arylcyclopropanes via double C–H activation and the coupling of two alkyl groups. Finally, targeting the herbicide Indaziflam contributed to develop C(sp3)–H activation as a powerful tool to access a variety of relevant indane motifs. We hope that these successful stories will help to stimulate further fruitful Industry-Academia collaborations in the field of synthetic chemistry.

Resumen

Our research focusses on highly sustainable enzymatic methods for the preparation of valuable molecules, spanning from pharmaceuticals, to small chiral intermediates, to flavours and perfumes. Specifically, we aim at developing strategies which will rapidly bridge the gap between academic discovery and industrial implementation. The use of enzymes in industrial processes is becoming more prominent and there is a need to combine the advantages of biocatalysis with high productivity to make it truly attractive. We have been among the pioneers of a new wave of research in the field of flow biocatalysis: whole cells expressing biocatalysts and cell-free systems have been developed by us and others in continuous systems for the preparation of valuable products. Continuous flow biocatalysis is the state of the art in continuous processing and is showing new exceptional properties of enzymes specially for what concerns their efficiency and long-lasting reusability. Here we report on the recent progress in the field by our research group.

Resumen

This review relates 85 years of catalysis performed at Firmenich. A special emphasis is shown on how the industry has always focussed on improving the environmental profile of the perfumery ingredients produced and on making them more sustainable. In particular through the application of one of the key principles of Green Chemistry, no. 9, which concerns catalysis. These trends have of course impacted the choice and the need for industrial processes that generate less waste, use less solvent and minimize energy requirements. This review has been organized around key transformations used at Firmenich, and a comparison between stoichiometric and catalytic approaches for some important perfumery ingredients is presented.

Resumen

The synthesis of drug substances (DS) requires the continuous effort of the pharma industry to ensure high sustainability standards. Suzuki Miyaura cross coupling is a fundamental C-C bond-forming reaction to produce complex DS intermediates. The present contribution points out the way, in which the synthesis of DS intermediates by C-C cross coupling can be economically competitive, while minimizing waste by selecting the appropriate heterogeneous catalyst. By comparing homogeneous, immobilized heterogeneous catalysts on silica and metal-organic framework (MOF) catalysts, while considering the perspectives of academia and industry, the critical parameters for a successful industrial application of heterogeneous catalytic Suzuki Miyaura cross coupling reactions were identified. Heterogeneous catalysts, such as MOFs, may provide the complementary platform for reducing waste and the costs of production related to such transformations.

Resumen

Over the past decades, scientists at Firmenich have focused their efforts on continuously improving chemical transformations for the production of F&F ingredients in order to make them safer, cleaner, more efficient and consequently cost effective, through the implementation of the Green Chemistry principles. Numerous examples of innovative catalytic technologies could be cited, particularly in the field of homogeneous and heterogeneous catalytic hydrogenation. Nevertheless, we chose here to provide a rare insight into the industrial application of some very useful and atom-economic carbon–carbon bond forming reactions. We selected two examples among others as a good illustration of how catalysis makes the difference compared to conventional stoichiometric approaches. The first example deals with catalysed cross-aldol condensation and the second example concerns catalysis of cross-coupling reactions.

Resumen

Enzymes are versatile biocatalysts capable of performing selective reactions. The advantages of enzymes in comparison to classical chemistry including chemical catalysts are the generally milder process conditions and avoidance of harmful reactants. Their high selectivity and specificity are especially beneficial for the enzymatic synthesis of new products with potential applications in drug research. Therefore, in the past decades, the utilization of isolated enzymes or whole-cell biocatalysts has spread through a growing number of biotechnological industries. The applications comprise the production of chiral building blocks for the pharmaceutical and fine chemical industry, the enzymatic synthesis of drug metabolites for testing of toxicity, function, biological activity, degradation and the production of biocatalytically modified natural products, which all play a role in drug discovery. Especially Oreste Ghisalba's contributions, which paved the way for the industrial use of enzymes, will be considered in this review.

Resumen

In this work, we discuss the application of a gas diffusion electrode (GDE) setup for benchmarking electrocatalysts for the reductive conversion of CO2 (CO2 RR: CO2 reduction reaction). Applying a silver nanowire (Ag-NW) based catalyst, it is demonstrated that in the GDE setup conditions can be reached, which are relevant for the industrial conversion of CO2 to CO. This reaction is part of the so-called 'Rheticus' process that uses the CO for the subsequent production of butanol and hexanol based on a fermentation approach. In contrast to conventional half-cell measurements using a liquid electrolyte, in the GDE setup CO2 RR current densities comparable to technical cells (>100 mA cm–2) are reached without suffering from mass transport limitations of the CO2 reactant gas. The results are of particular importance for designing CO2 RR catalysts exhibiting high faradaic efficiencies towards CO at technological reaction rates.

Resumen

Today, the production of food accounts for roughly one quarter of anthropogenic greenhouse gas emissions. Since the 1970s, thanks to substantial research and development, the overall yield output in farm fields has increased by ca. 60%, while the net use of crop protection agents per square meter of farm field has been reduced by more than 90%. The development of modern crop protection agents remains an important need as new pests, diseases and weeds continue to affect crops. The vast majority of these effective solutions are manufactured using raw materials that ultimately come from fossil resources. In this article, we are touring within the agrochemical landscape to provide the reader with an overview of concrete examples on how in this industrial field, renewable and sustainable raw materials have been used to produce active ingredients. We are also discussing the opportunities for future development as well as some of the challenges and needs that are emerging.

Il s’agit de secteurs variés : chimie, aluminium, papier et carton, sidérurgie, ciment, plastiques, verre. Dans ces secteurs, la maîtrise de la facture d’électricité est un critère déterminant de compétitivité. Elle représente de l’ordre de 10 à 20 % des coûts de production, voire jusqu’à 80 % dans des cas extrêmes d’hyper-intensivité.

Resumen

A scale-flexible process for the direct and selective oxidation of methane to primary oxygenates is of great interest, however, a commercially feasible approach has yet to be realized due to a number of challenges. Low product yields imposed by a well-established selectivity-conversion limit are particularly burdensome for direct methane-to-methanol chemistry. One strategy that has emerged to break out of this limit is the in situ esterification of produced methanol to the more oxidation-resistant methyl ester. However, these methaneto-methyl-ester approaches still elude commercialization despite their unprecedented high yields. Herein, we outline some of the key barriers that hinder the commercial prospects of this otherwise promising route for highyield direct catalytic methane conversion, including extremely corrosive reagents, homogeneous catalysts, and inviable oxidants. We then highlight directions to address these challenges while maintaining the characteristic high performance of these systems. These discussions support the efficacy of product protection strategies for the direct, selective oxidation of methane and encourage future work in developing creative solutions to merge this promising chemistry with more practical industrial requirements.

Resumen

Biosurfactants are surface-active molecules, developed by nature through evolution and naturally produced by different microorganisms. The most prominent examples are rhamnolipids and sophorolipids, molecules which contain hydrophilic sugar head groups and hydrophobic alkyl residues leading to an amphiphilic behavior with unique properties. Recent developments in the field of biotechnology enable the large-scale production of these biological molecules. The raw material basis is 100% renewable since sugars and oils are used as major raw materials. Additionally, biosurfactants are fully biodegradable, which allows the path back into the natural cycles. In comparison to established standard surfactants like SLES/SLS (sodium laureth (ether) sulfates) or betaines, rhamnolipids are much milder and, at the same time, show similar or even better performance in household or personal care applications. Foam behavior, solubilization and cleaning effectiveness are examples where these natural substances give excellent results compared to the synthetic benchmarks. The commercialization of biosurfactants at industrial scale now offers alternatives to consumers seeking sustainable solutions, without compromising performance. Biosurfactants combine both and set a new standard for surfactant applications.

Resumen

CFCs (chlorofluorocarbons) and other strong ozone-depleting halogenated organic trace gases were used in numerous industrial, household and agriculture applications. First atmospheric measurements of CFCs were performed in the 1970s, well ahead of the detection of the ozone hole in the 1980s. The continuous observation of these ozone-depleting substances (ODSs) is crucial for monitoring their global ban within the Montreal Protocol. In addition, also HFCs (fluorinated hydrocarbons) are measured, which were introduced as substitutes of ODSs and are potent greenhouse gases. Since 2000, Empa continuously measures more than 50 halogenated trace gases at the high-Alpine station of Jungfraujoch (3850 m asl) as part of the global AGAGE network (Advanced Global Atmospheric Gases Experiment). Jungfraujoch is the highest location worldwide where such measurements are performed, and the site where several of these compounds were measured in the atmosphere for the first time. The measurements at Jungfraujoch and at other globally well-positioned sites serve as an early warning system, i. e. before potentially harmful halogenated organic substances can accumulate and detrimentally affect the natural environment.

Resumen

Despite the availability of a variety of ' -omics ' technologies to support the system-wide analysis of industrially relevant microorganisms, the manipulation of strains towards an economically relevant goal remains a challenge. Remarkably, our ability to catalogue the participants in and model ever more comprehensive aspects of a microorganism's physiology is now complemented by technologies that permanently expand the scope of engineering interventions that can be imagined. In fact, genome-wide editing and re-synthesis of microbial and even eukaryotic chromosomes have become widely applied methods. At the heart of this emerging system-wide engineering approach, often labelled ' Synthetic Biology ' , is the continuous improvement of large-scale DNA synthesis, which is put to two-fold use: (i) starting ever more ambitious efforts to re-write existing and coding novel molecular systems, and (ii) designing and constructing increasingly sophisticated library technologies, which has led to a renaissance of directed evolution in strain engineering. Here, we briefly review some of the critical concepts and technological stepping-stones of Synthetic Biology on its way to becoming a mature industrial technology.

Resumen

The sustainability of the pharmaceutical industry has aroused interest from various sectors and disciplines, including chemistry, biology and engineering. Given the Swiss drug sector’s innovative engine and enormous economic importance, a Swiss Biotech Day panel discussion was held in May 2022 in Basel to address the question of how “sustainability across the pharmaceutical value chain” can be edged forward in Switzerland. Roche, Lonza, Pheida, ETH, the Swiss Academy of Engineering Sciences (SATW), and a newly established collaborative, Circular Carbon for Chemistry (ccLoop) joined forces and agreed that sustainability must become a key strategic goal for the industry in Switzerland. The panel looked at the sustainability challenge, at how a green transition can be achieved faster, and at how industrial biotechnology applications can improve industry’s performance, energy efficiency and product value while yielding viable sustainable solutions to protect our environment. Switzerland is a leader in drug development and manufacturing. By placing greater energy and resources on the sustainability equation, we ensure continued leadership and a greener world. ‘Swissness’ will increasingly have to denote effective drugs produced sustainably. sustainably.

Resumen

The selective partial oxidation of methane to methanol remains a great challenge in the field of catalysis. Cu-exchanged zeolites are promising materials, directly and selectively converting methane to methanol with high yield under cyclic conditions. However, the economic viability of these aluminosilicate materials for potential industrial applications remains a challenge. Exploring copper supported on non-microporous oxide supports and rationalising the structure/reactivity relationships extends the scope of material investigation and opens new possibilities. Recently, copper on alumina was demonstrated to be active and selective for the partial oxidation of methane. This work aims to explore the formation of well-defined Cu(II) oxo species on silica via surface organometallic chemistry and examines their reactivity for the selective transformation of methane to methanol. Isolated Cu(II) sites were generated via grafting of a tailored molecular precursor. Activation under oxidative conditions and subsequent removal of organic moieties from the grafted copper centres led to the formation of small copper (II) oxide clusters, which are active in the partial oxidation of methane under mild conditions, albeit significantly less efficient than the corresponding isolated Cu(II) sites on alumina.

Resumen

In 1983, Lonza Ltd. initiated a small research group serving as a nucleus for the introduction of biotechnology to our organic intermediates and fine chemicals business. Over the past years we experienced vigorous growth and two projects reached industrial maturity: i) 6-Hydroxynicotinic acid (1) is a versatile building block derived by regiospecific hydroxylation of nicotinic acid (or niacin) (2), a B-group vitamin produced by Lonza. Thus, our first biotechnological product is fully integrated into the main product stream of Lonza's chemical production. ii) L-Carnitine (3) is synthesized by stereospecific hydroxylation of 4-butyrobetaine (4) in a β-oxidation process analogous to fatty-acid degradation. L-Carnitine (3) is a vitamin-like substance with interesting physiological capacities. Both processes are based on interrupted catabolic pathways of microbial origin. Production is on a multi-ton scale.
