A method for increasing selectivity of alkylation to monoalkylation comprising: providing a feedstream consisting essentially of alkylating agent and a stoichiometric excess of benzene, the alkylating agent consisting essentially of a molar blend of propylene and one or more linear butene(s); and, contacting the feedstream with a catalytically effective amount of zeolite beta under alkylation reaction conditions which increase selectivity of the alkylation to monoalkylation compared to predicted selectivity to monoalkylation based on the concentration of the alkylating agent and on the molar blend of propylene and one or more linear butene(s).
一种增加烷基化选择性以进行单烷基化的方法,包括:提供一种由烷基化试剂和苯的化学计量过剩组成的进料流,所述烷基化试剂由丙烯和一种或多种线性丁烯的摩尔混合物组成;并在烷基化反应条件下,将该进料流与催化效果充分的β型沸石接触,以增加烷基化选择性,使其比基于烷基化试剂浓度和丙烯和一种或多种线性丁烯的摩尔混合物的预测选择性更趋向于单烷基化。
