摘要
对国内炼厂碳四的利用状况进行了分析,对混合碳四与甲醇合成甲基叔丁基醚,正丁烯经水合、脱氢反应制备甲乙酮和正丁烯与乙酸反应制备乙酸仲丁酯的生产情况进行了介绍;对醚后混合碳四制丙烯和乙烯、异构化制异丁烯、芳构化、与乙酸反应制备乙酸仲丁酯的应用和研究状况进行了分析,认为利用醚后混合碳四制备丙烯和制备乙酸仲丁酯是未来的发展方向;对异丁烷脱氢、异丁烷选择氧化、正丁烷制顺酐等技术研究进展和使用现状进行简述,认为异丁烷的利用是未来的研究重点。
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.
