Abstract:

Pentaerythritol is an important industrial chemical for use in paints and coatings, primarily, but also in fuels, explosives, medicine and polymers. The current process for this material is over 50 years old and is a multi-step process involving 3 homogeneous aldolizations and a crossed Cannizzaro reaction, generating 1.5 tonnes of waste for every 4 tonnes of product. This is also very energy inefficient. We are currently developing a radically different concept, shown below. This will deliver an integrated heterogeneous catalytic process with no waste and a high energy and materials efficienc

Abstract:

In order to investigate the details of hydrogen bonding and solution molecular conformation of complex alcohols in water, isobaric-isothermal Monte Carlo simulations were carried out on several systems. The solutes investigated were ethanol, ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol and glycerol. In addition, propane, which does not hydrogen bond but does form water hydrates, was simulated in aqueous solution. The complex alcohol-water systems are very nonideal in their behavior as a function of solute concentration down to very dilute solutions. The water model employed was

碩士<br>國立中興大學<br>森林學系<br>91<br>SUMMARY China fir (Cunninghamia lanceolata) and Taiwan acacia (Acacia confusa) wood were liquefied in polyhydric alcohol at the presence of H2SO4 as catalyst. The effects of wood species, molecular weight of polyethylene glycol (PEG), PEG/Glycerol ratio, catalyst content, and treatment time on liquefaction result were investigated in this study. In preparation of polyurethane(PU) foam, these liquefied woods were further reacted with four kinds of isocyanate, such as HDI (Hexamethylene diisocyanate)、PMDI (Polymeric methylene diphenylene diisocyanate)、Des

In addition, the performance of waterborne PU resins those prepared with ethylenediamine (EDA) and 1,4-butanediol (1,4-BD) as chain extender was compared. Furthermore, the modified waterborne PU resin that containing alkoxysilane groups was prepared by adding 3-aminopropyltriethoxysilane (APTES) during resins synthesis. The p

The residue content, viscosity, nonvolatile, acid number and hydroxyl number of the liquefied materials were used as the index to evaluate the efficiency of liquefaction. The liquefied materials were blended with PMDI (poly-4,4’-diphenylmethane diisocyanate), and adding water as a blowing agent, organosiloxane as a surfactant and dibutyl tin dilaurate as a catalyst to prepare the

Abstract:

碩士<br>國立臺灣師範大學<br>化學系<br>103<br>Cupric oxide as anode for lithium ion batteries(LIB) has attracted much attention due to its high theoretical capacity(~670mAh g-1) and low cost. However, the disadvantages are poor electrical conductivity and large volume expansion during lithiation resulting in fast fading of the capacity of cupric oxide. In this study, we synthesized hollow polyhydron rGO-Cuox by two step sintering graphene oxide and metal-organic frameworks compound [Cu3(btc)2]n(btc = benzene-1,3,5-tricarboxylate). The obtained rGO-Cuox materials were used in a lithium-ion battery and tested

Image processing pipelines are ubiquitous. Every image captured by a camera and every image uploaded on social networks like Google+or Facebook is processed by a pipeline. Applications in a wide range of domains like computational photography, computer vision and medical imaging use image processing pipelines. Many of these applications demand high-performance which requires effective utilization of modern architectures. Given the proliferation of camera enabled devices and social networks optimizing these emerging workloads has become important both at the data center and the embedded device
