General description

Hexane is an unbranched alkane that exists in five structural isomeric forms, i.e. hexane, isohexane, 3-methylpentane, neohexane, and 2,3-dimethylbutane. It can be obtained from petroleum by distillation.

application

Hexane can be used:      
  • As a solvent for the extraction of oil, wax, and fat.     
  • As a non-polar solvent in chromatographic applications for product separation and purification.

It is also used in the preparation of organolithium reagents because it cannot be easily deprotonated.
