The performance of three hydrophobic carboxylic acid based Deep Eutectic Solvents were evaluated for the extraction 1-butanol and acetonitrile from aqueous solution. To do so, phase diagrams five ternary systems {[DL-menthol: lauric acid] + water 1-butanol}, capric acetonitrile}, {[TBAMBr:capric 1-butanol} {[TBAMBr: measured at 298.15 K atmospheric pressure. Liquid-liquid equilibria data used t...

Introduction Conclusions References

A simple, selective and precise stabilityindicating HPLC method for determination of glabridin diacetate and dihexanoate prodrugs was developed, validated and applied to the enzymatic and chemical hydrolysis studies. The chromatographic separation was achieved on a reverse phase C18 (Thermo Hypersil-Keystone, 250 × 4.6 mm, 5 micron) column using the mixture of acetonitrile and water as mobile p...

Acetonitrile is a choice of solvent for almost all chromatographic separations. In recent years, researchers around the globe have faced an acetonitrile shortage that affected routine analytical operations. Researchers have tried to counter this shortage by applying many innovative solutions, including using ultra performance liquid chromatography (UPLC) columns that are shorter and smaller in ...

A quasichemical method that combines ab initio treatment of explicit solvent with dielectric continuum models has been used to study the origin of a strong effect of methanol on the extent of iron(III) [tetrakis(pentafluorophenyl)]porphyrin chloride dissociation in acetonitrile-methanol solutions. It is shown that the dissociation is energetically more favorable in methanol than in acetonitrile...

By using silver cations (Ag⁺) as the ionic reagent in reactive extractive electrospray ionization mass spectrometry (EESI-MS), the concentrations of acetonitrile in exhaled breath samples from the volunteers including active smokers, passive smokers, and non-smokers were quantitatively measured in vivo, without any sample pretreatment. A limit of detection (LOD) and relative standard deviation ...

RESUMO –In this work, it is shown that aqueous two-phase systems can be formed by the combination of acetonitrile and polysaccharides, namely dextran biopolymers. The respective ternary phase diagrams were determined at 25 oC for the systems composed of water + acetonitrile + dextran. The effect of the dextran molecular weight was also ascertained toward their ability to undergo liquid-liquid d...

Cellular metabolome analysis by chromatography-mass spectrometry (MS) requires prior metabolite extraction. We examined a diversity of solvent systems for extraction of water-soluble metabolites from Escherichia coli. Quantitative yields of approximately 100 different metabolites were measured by liquid chromatography-tandem MS and displayed in clustered heat map format. Many metabolites, inclu...
