【摘要】：以煤化工产品为烯烃原料,通过与苯的烷基化反应,并在氢氟酸催化剂的作用下合成了重烷基苯。考察反应温度、压力和时间、苯烯摩尔比及催化剂用量对反应的影响。结果表明,在反应温度90℃,压力0.5 MPa,反应3.5 h,苯烯摩尔比8.33,催化剂用量9%条件下,液体收率84.3%,重烷基苯、饱和烷烃和副产物的产率分别为96.2%,17.4%和5.8%,82.4%的苯回收率说明苯可以循环利用。由此证明以煤化工产品为烯烃替代原料,与苯通过烷基化生成重烷基苯反应的可行性。
[Abstract]:Heavy alkylbenzene was synthesized by alkylation of benzene with coal chemical products as olefin feedstock and under the action of hydrofluoric acid catalyst. The effects of reaction temperature, pressure and time, molar ratio of phenylene and amount of catalyst on the reaction were investigated. The results showed that under the conditions of reaction temperature 90 鈩，
