一般描述

Toluene, a benzene analog, is widely employed as an organic solvent. It has been reported to be a biotoxic solvent (toxic to many microorganisms at 0.1%v/v concentrations). Its anaerobic biodegradation to CO2, by the denitrifying bacterium Thauera arornatica has been reported. It forms a syndiotactic polystyrene-toluene molecular compound. Crystal structure of this molecular compound has been investigated by X-ray diffraction studies.

应用

Toluene may be used as a doping agent during the quantitative estimation of triacylglycerols (TAGs) by liquid chromatography-atmospheric pressure photoionization-mass spectrometry (LC-APPIMS). It has been reported to improve the sensitivity of analysis. It may be used as solvent for the preparation of 4-arm polylactide-based (PLA) star oligomer.

In this work, we evaluate the performance of liquid chromatography-atmospheric pressure photoionization-mass spectrometry (LC-APPI-MS) for non-aqueous reversed phase analysis of six triacylglycerol model compounds using six binary mobile phases including MeOH/iPrOH, MeOH/CHCl(3), MeOH/CH(2)Cl(2), CH(3)CN/iPrOH, CH(3)CN/CHCl(3), and CH(3)CN/CH(2)Cl(2).

Toluene is degraded anoxically to CO2 by the denitrifying bacterium Thauera aromatica. Toluene first becomes oxidized to benzoyl-CoA by O2-independent reactions. Benzoyl-CoA is then reduced to non-aromatic products by benzoyl-CoA reductase. We set out to study the reactions employed for

Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water by planar solid phase extraction – planar yeast estrogen screen (pSPE-pYES).
