General description

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).[16] Its anaerobic biodegradation to CO2, by the denitrifying bacterium Thauera arornatica has been reported.[17] It forms syndiotactic polystyrene-toluene molecular compound. Crystal structure of this molecular compound has been investigated by X-ray diffraction studies.[18]

Application

Toluene may be used in the following studies:
  • 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.
[09]
  • For the decontamination of microbial cultures and lyse bacterial cells in bacterial enzyme assays.
  • [16]
  • As a solvent for the preparation of 4-arm polylactide-based (PLA) star oligomer.
  • [04]
