说明

一般說明

Hexane is an alkane hydrocarbon having 5 structural isomeric forms. It is a colorless, combustible liquid. It is one of the essential components of petroleum ether. It can be obtained from petroleum by distillation. It can also be produced by electrolysis of potassium butyrate. It is widely employed organic solvent for the dissolution of fats and oils.

應用

Hexane has been used in the preparation of graft-copolymer chains of poly-(dimethylsiloxane)-g-poly(methyl methacrylate). It has been employed for the GC/MS characterization of essential oils extracted from various origins.
