Solvent extraction is a common technique utilized for both industrial applications and in the laboratory. The technique is successfully applied as a sample preparation procedure for chromatography. It can be used for separation purposes by using selective extractions, or for concentration purposes.

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.

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 ...

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 ...

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.

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 ...

We report on the rotational diffusion dynamics of two different chromophores, resorufin and 6-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)hexanoic acid (NBDHA) in water and N-octyl-2-pyrrolidone (NOP) solvents. We measure the induced orientational anisotropy function, R(t), using time-correlated single photon counting.
