Abstract: This paper analyzes utilization of C4 in China，and introduces the manufactures of methyl tert-butyl ether synthesized from mixed C4 and methanol，methyl ethyl ketone prepared by n-butene through hydration reaction and dehydrogenation reaction，sec-butyl acetate from n-butene and acetic acid. Also，it briefly describes the investigations on reactions of mixed C4 after production of MTBE to prepare propylene and ethylene，isobutene by isomerization，sec-butyl acetate by reaction with acetic acid，and aromatization. Accordingly，it forecasts their market prospects respectively. Preparations of propylene and sec-butyl acetate from mixed C4 are proved to be the most promising ways. Through comparing the technologies of isobutane dehydrogenation，selective oxidation of isobutane，and reaction of n-butane to prepare maleic anhydride，utilization of iso-butane is thought to be future research focus.
