1,2-DICHLOROBUTANE Chemical Properties,Usage,Production

Uses

1,2-Dichlorobutane was used to evaluate temperature-composition phase diagrams of binary mixtures composed of a haloalkane dissolved in either 1-ethyl-3-methylimidazolium ethylsulfate or 1-ethyl-3-methylimidazolium ethylsulfonate.

General Description

1,2-Dichlorobutane causes the alkylation of benzene using aluminium chloride or liquid hydrogen fluoride as catalyst.
