Clinics in Occupational and Environmental Medicine, 2004
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 (

Solvent effects on the wood delignification with sustainable solvents
International Journal of Biological Macromolecules, 2022Solutions of a pure organic solvent acidified with 1% sulfuric acid, and some of their aqueous mixtures were used for lignin extraction in the Pinus radiata sawdust delignification. Organic acid solvents including acetic, lactic and citric acids as well as non-acidic compounds such as γ-valerolactone, 2-methyltetrahydrofuran, glycerol and ethylene ...

Chlorinated Solvents and Solvent Stabilizers
2020This chapter deals with the stabilizers for the chlorinated solvents, which were by far the most frequently used solvents for degreasing, dry cleaning, cold cleaning, and dozens of other industrial applications. 1,4-Dioxane, a probable human carcinogen, has manifested as the most significant drinking water and environmental contaminant among the dozens

The rates of the reactions of benzhydrylium ions (diarylcarbenium ions) with solvent mixtures of variable composition (water/acetonitrile, methanol/acetonitrile, ethanol/acetonitrile, ethanol/water, and trifluoroethanol/water) have been determined photometrically by conventional UV-vis spectroscopy, stopped-flow methods, and laser flash techniques.

Solvents and Solvent Effects: An Introduction
Organic Process Research & Development, 2006Solution chemistry is carried out in solvents, that is in liquids under the conditions of application, which can exert a considerable influence on the properties of the dissolved solute species. A short historical overview on the influence of solvents on chemical processes (equilibria, reaction rates) and physical processes (absorption spectra ...

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.

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 ...

Solvent form examines the destruction of art—through objects that have been destroyed (lost in fires, floods, vandalism, or similarly those artists that actively court or represent this destruction, such as Gustav Metzger), but also as a process within art that the object courts through form.

AORN Journal, 1971
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 ...
