Hygroscopic effects in ionic liquids and salts general, how to suppress said hygroscopy, often needs be considered during the everyday work routine. Chemicals that decompose, undergo hydrolysis or any way change their composition when exposed air are generally not bench-stable. In this study, we synthesized a low-hygroscopic, bench-stable carbohydrate-based hydroxide salt. This new product was ...

(Ligno)cellulose is mainly composed of cellulose, lignin, hemicellulose, and extractives, which represents an abundant carbon-neutral renewable resource. Increasing concerns about global warming and diminishing fossil fuel reserves have stimulated much effort to use (ligno)cellulose as an alternative to petroleum for the production of fuels and chemicals. From a sustainability point of view, sh...

Partition coefficients are required for developing physiologically based pharmacokinetic models used to assess the uptake, distribution, tabolism, and elimination of volatile chemicals in mammals. A gas-phase vial equilibration technique is presented for determining the liquid:air and tissue:air partition coefficients for low-molecular-weight volatile chemicals. This technique was developed fro...

A novel process design for a more cost-effective, greener process for making chemicals from shale gas and bioethanol is presented. The oxidative coupling of methane and cocracking technologies are considered for converting methane and light natural gas liquids, into value-added chemicals. Overall, the process includes four process areas: gas treatment, gas to chemicals, methane-to-ethylene, and...

Bifunctional acidic ionic liquids, having both H-imidazolium and -SO3H groups as cation moieties (H-BFAILs) and CF3SO3- as anion, were synthesized in high yields. These H-BFAILs showed significant hydrophilic properties, lower acidity and higher thermal stability relative to common ionic liquids, due to their unique structures. The (propyl or butyl-3-sulfonic) imidazolium trifluoromethane sulfo...

A new ion source has been developed for rapid, noncontact analysis of materials at ambient pressure and at ground potential. The new source, termed DART (for "Direct Analysis in Real Time"), is based on the reactions of electronic or vibronic excited-state species with reagent molecules and polar or nonpolar analytes. DART has been installed on a high-resolution time-of-flight mass spectrometer...

Lignin is considered by many as the ultimate barrier that impedes biomass conversion to fuels and chemicals. Several delignification strategies have been developed so far, but alkaline extraction remains most widely used. However, this technology has a high chemical demand, consumes large amounts of water, generates effluents are hard handle. Organosolv pulping good option for such application,...

Abstract Background Ionic liquids (ILs) are promising pretreatment solvents for lignocellulosic biomass, but largely prepared from petroleum precursors. Benzaldehydes depolymerized lignin, such as vanillin, syringaldehyde, and 4-methoxy benzaldehyde, represent renewable feedstocks the synthesis of ionic liquids. We herein report syntheses novel lignin-derived liquids, with extended N -alkyl cha...

In recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ILs) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. Sonic speed is an important thermodynamic property of ionic liquids (ILs) and always chosen as a source to determine other properties. A database for the sonic speed of pure ILs cre...

Sustainable development strategies, as well the shift toward a circular bioeconomy, has led to high interest in and implementation of technologies that efficiently utilize biomass raw material. Switching from fossil-based bio-based resources requires consideration many new challenges problems. One crucial issues is solubility lignocellulose or at least its ingredients. According trends legislat...
