Despite the number of substances that fall under the rubric of solvent, only a few are considered to be potential carcinogens. The purpose of this article is to provide readers with an overview of the cancer data that exist for a number of solvents currently in commercial use. These solvents include chloroform, carbon tetrachloride, methylene chloride (

Deep Eutectic Solvents as Efficient Solvents in Biocatalysis
Trends in Biotechnology, 2019'Ideal' solvents in biocatalysis have to fulfill a large number of requirements, such as high substrate solubility, high enzyme activity and stability, and positive effects on reaction equilibrium. In the past decades, many enzymatic synthesis routes in water-based and nonaqueous (organic solvents, ionic or supercritical fluids) reaction media have ...

AbstractThe ET polarity values of 4‐[(1‐methyl‐4(1H)‐pyridinylidene)ethylidene]‐2,5‐cyclohexadien‐1‐one, better known as Brooker's merocyanine, were collected in binary mixtures comprising a non‐protic [acetonitrile, dimethyl sulfoxide (DMSO) and acetone] and a protic (water, methanol, ethanol, propan‐2‐ol and butan‐1‐ol) solvent.

The solvent power of solvents for cellulose nitrate
Journal of Applied Chemistry, 1955AbstractThe osmotic pressures of dilute solutions of 12.2%‐nitrogen‐content cellulose nitrate have been determined, with homologous series of methyl ketones and alkyl acetates as solvents. Values of the interaction constant μ have been estimated from the slopes of plots of reduced osmotic pressure against concentration.

Worldwide, several hundred million tons of organic solvents are used annually in household, industry, and other occupational settings. Millions of workers are regularly exposed to organic solvents considered neurotoxic. Acute neurotoxicity due to high exposure of solvent is usually evident, but the nature of long-term effects, such as chronic solvent ...

In Situ Solvent Recovery by Organic Solvent Nanofiltration
ACS Sustainable Chemistry & Engineering, 2014Reducing solvent consumption in the chemical industries is increasingly becoming a topic of interest. The field of organic solvent nanofiltration (OSN) has markedly evolved in the past decade, and effective membranes are now available that can withstand aggressive solvents while completely rejecting small solutes at the lower end of the nanofiltration ...

There has been a relative neglect in removing Ether from many operating rooms. This neglect is highlighted because of its obvious importance as an explosion hazard. The statistical frequency of explosions in the operating room remgins at l/lSO,OOo onesthestio.' In the light of present technics and knowledge this number should be even lower, and we as ...

α‐Helix formation by solvent–solvent interaction
Biopolymers, 1967AbstractThe degree of helicity θ of a series of homologous polypeptides as a function of solvent composition was investigated. The polypeptides studied were: poly‐N5‐(3‐hydroxypropyl)‐L‐glutamine (PHPG) as well as the corresponding 2‐hydroxyethyl and 4‐hydoxybutyl derivatives (PHKG and PHBG, respectively).

Solvent reorganization of electron transitions in viscous solvents
The Journal of Chemical Physics, 2006We develop a model of electron transfer reactions at conditions of nonergodicity when the time of solvent relaxation crosses the observation time window set up by the reaction rate. Solvent reorganization energy of intramolecular electron transfer in a charge-transfer molecule dissolved in water and acetonitrile is studied by molecular dynamics ...
