Abstract:

Methylene chloride, commonly known as dichloromethane (DCM), is a widely used chemical for chromatography separation within the polymer, chemical, and pharmaceutical industries. With the ability to effectively solvate heterocyclic compounds, and properties including a low boiling point, high density, and low cost, DCM has become the solvent of choice for many different applications. However, DCM has high neurotoxicity and is carcinogenic, with exposure linked to damage to the brain and the central nervous system, even at low exposure levels. This research focuses on sustainability and works to

Abstract:

1 Although there are trends towards the use of 'safer' or non-solvent materials, the overall consumption of solvents will probably not change very much over the next few years. Substitution of solvents by 'safer' materials is a complex and difficult process and the rate of change is correspondingly slow. 2 HSE exposure data show that generally industry controls most solvent use quite well. High personal exposures are not widespread and tend to occur in a fairly small number of premises involving 'end user' processes (mixing, spraying, etc). 3 Exposure in industry is generally to mixtures of so

Magnesium (Mg) batteries are regarded as safer alternatives for Li+-dominated batteries by virtue of the unique dendrite-free property of Mg element.

These kinds of electrolytes seriously violate the original purpose of developing Mg-based batteries. Therefore, exploring non-flammable chloride-free solid-state electrolytes is of significant

Abstract:

Safety is a critical consideration in the oil mill industry, particularly in the context of solvent extraction processes. This study focuses on the safety concerns associated with various solvents used in oil extraction, highlighting the potential risks to workers and end consumers, as well as environmental impacts. The analysis reveals that alcohols, such as ethanol and isopropanol, generally offer better safety profiles compared to hexane, despite presenting higher risks in terms of ATEX (explosive atmosphere) considerations at ambient temperature. These alcohols have higher electrical condu

Abstract:

Trichloroethylene is a solvent currently used by the Florida Department of Transportation (FDOT) and many state highway agencies for separation of asphalt binders from asphalt paving mixtures in their quality control programs. However, it has been proved that trichloroethylene contributes to ozone depletion, and it is also known to be a carcinogen. The goal of the present study was to determine whether a more environmentally sound and less hazardous solvent could be used for this purpose. The solvent investigated is an n-propyl bromide with the trade name EnSolv. Preliminary studies show that

Abstract:

The liquid electrolyte transports lithium ions from anode to cathode during charging, and vice versa. The choice of electrolyte is also important since high ionic conductivity between electrodes is essential for high-performance batteries. Liquid electrolytes with lithium salt dissolved in an organic solvent have been widely used since the 1970s when lithium primary batteries were first developed. Most lithium secondary batteries available today use organic electrolytes. Ionic liquids consist of organic cations and inorganic anions, due to the absence of a combustible and flammable organic sol

Abstract:

The purpose of this study was to synthesize polysubstituted tetraarylphosphonium/tetrakis (pentafluorophenyl) borate salts 3, also known as TAPR/TFAB where R is a substituent, and to measure their conductance/conductivity in low-polarity media such as tetrahydrofuran (THF) and dichloromethane (DCM). Such determination was to provide a rationale to the question of whether these compounds, and other weakly coordinating cations/anions combinations are suitable electrolytes for advanced batteries which are energized in safer, low-polarity organic solvents.

Abstract:

Laropal® A81 is a urea-aldehyde resin used as a varnish for paintings requiring 30%–40% of aromatic solvents to be dissolved. Considering the dangers of aromatic solvents for the environment and health, an attempt was made to replace them with less impactful and low-toxic solvents. The present research investigates a new formulation with aliphatic hydrocarbons and esters (isobutyl isobutyrate, IBIB) as an alternative to traditional aromatics mixture. Traditional and alternative varnish formulations of Laropal® A81 were studied on an inert support and paint samples to test the resin by itself a

It is well known that emulsifiable concentrates (EC), besides good properties have problem with a high solvent content thus are not environmental friendly and can cause problems for users. The interest in developing oil-in-water emulsions (EW) instead emulsifiable concentrates is increasing due to toxicological problems with solvents. Oil-in-water emulsions can reduce phytotoxicity, ecotoxicity and dermal toxicity, have a higher flash point than EC and are safer in transport and storage; also EW are more compatible with water based SC formulations for blends of active ingredients.

There is a strong need to transition away from N-Methyl-2-pyrrolidone (NMP) and adopt more sustainable processes. Arkema has recently developed novel Waterborne-PVDF (WB-PVDF) Binders suitable for role-to-role cathode fabrication. This innovation is a testament to Arkema’s commitment to greener and safer production methods without compromising on quality. Waterborne binders eliminate the need for solvent recovery/cycling systems, which is costly and energy intensive. The novel WB-PVDF binder aligns with sustainability goals, as reduces the carbon footprint and environmental impact associated w

Abstract:

Piroxicam (PRX) is a commonly prescribed nonsteroidal anti-inflammatory drug. Its efficacy, however, is partially limited by its low water solubility. In recent years, different studies have tackled this problem and have suggested delivering PRX through solid dispersions. All these strategies, however, involve the use of potentially harmful solvents for the loading procedure. Since piroxicam is soluble in supercritical CO2 (scCO2), the present study aims, for the first time, to adsorb PRX onto mesoporous silica using scCO2, which is known to be a safer and greener technique compared to the org
