설명

일반 설명

Toluene, a benzene analog, is widely employed as an organic solvent. Its anaerobic biodegradation to CO₂, by the denitrifying bacterium Thauera arornatica has been reported. It forms syndiotactic polystyrene-toluene molecular compound. Crystal structure of this molecular compound has been investigated by X-ray diffraction studies.

애플리케이션

Toulene may be used as a solvent for the preparation of 4-arm polylactide-based (PLA) star oligomer. It was used for the activation of glass slides, for in vitro test system for allergy diagnosis.
