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.
