Abstract

Isopentene is produced in a high yield by a method wherein disproportionation of a hydrocarbon mixture containing n-butene and isobutene is carried out by bringing, at 200.degree. to 350.degree.C, the hydrocarbon mixture into contact with a composite catalyst which has been prepared by depositing a barium or strontium compound and a silver compound onto a carrier material consisting of an activated high purity alumina carrier to produce a precursory composite catalyst, calcining the precursory composite catalyst at 300.degree. to 900.degree.C, and isolating the resulted isopentene from the reaction mixture.
