异丙基苯合成路线

异丙基苯上游产品

异丙基苯下游产品

异丙基苯制备

1.由苯与丙烯进行烷基化反应而得。通常采用三氯化铝为催化剂、氯化氢为促进剂，反应在常压和95℃左右进行。除生成异丙苯外，还有二异丙苯、三异丙苯等多烷基副产物生成。为了减少副反应可采用过量的苯，苯与丙烯的摩尔比为3左右；三氯化铝在反应液中的含量为3%-8%；在低的丙烯浓度下进行反应。为提高反应器的生产能力，减少尾气中苯的损失，可将反应压力提高到0.5-0.6MPa。反应所得的烷基化液经冷却、沉淀后分离出的固体（三氯化铝与多异丙苯络合物）循环使用。烷基化液则经水解、中和、精馏而得异丙苯。另一种气相法工艺过程，是将气态苯和丙烯通过载于氧化铝或硅酸铝上的磷酸催化床层，进行催化烷基化，反应压力1.5-40MPa，温度约250℃。目前工业上生产异丙苯以上述液相法为主。

2.其制备方法是将苯和丙烯在催化剂三氯化铝存在下一起进入烃化塔，苯中含有少量氯化氢作为助催化剂，反应温度95～100℃，反应产物中含异丙苯30％～35％，多异丙苯10％～15％。反应液冷却，沉降分离，分出三氯化铝在多异丙苯中的配合物，除去乙苯，所得粗异丙苯经蒸馏而得成品。
