Technique for synthesizing methylheptenone

A process for cynthesizing methylheptenone features that under existance of catalyst, the methybutenol and methoxypropene take part in reaction in tower reactor under 1.5-3.5 atom for 1-8 hrs to obtain methylheptenone from tower bottom and methanol from tower top. Its advantages are high output rate...

Summary:A process for cynthesizing methylheptenone features that under existance of catalyst, the methybutenol and methoxypropene take part in reaction in tower reactor under 1.5-3.5 atom for 1-8 hrs to obtain methylheptenone from tower bottom and methanol from tower top. Its advantages are high output rate and purity. 本发明公开的甲基庚烯酮合成工艺，是在酸性催化剂存在下，以甲基丁烯醇和甲氧基丙烯为原料，于塔式反应器中进行反应，其中，甲氧基丙烯与甲基丁烯醇的摩尔比为1.0～1.2，催化剂用量为甲基丁烯醇重量的0.1％～2.0％，反应在常压或在1.5～3.0大气压下进行，反应时间为1～8小时。在塔顶得到甲醇，塔釜得到甲基庚烯酮。本发明采用反应精馏技术来合成甲基庚烯酮，收率和含量高，生产成本低，为一种绿色的合成工艺。
