Descrição geral

The product is a mixture of hexane isomers and methylcyclopentane. Hexane (mixture of isomers) can be isolated from petroleum by distillation or by cracking. They form major constituents of petroleum ether. It is a non-renewable organic solvent mainly used for the dissolution and extraction of oils and fats. Separation of the isomeric forms of hexane on the basis of degree of branching using Fe2(BDP)3 (BDP2- = 1,4-benzenedipyrazolate) has been reported.

Aplicação

Hexane (n-hexane) has been used in the preparation of precursor required for the synthesis of chiral stationary phase (IMPCSP). IMPCSP was employed for the enantioseparation of racemic drugs by high-performance liquid chromatography (HPLC) and supercritical fluid chromatography (SFC). It may be used as a carrier phase for microfluidic devices.
