摘　　要：从催化剂研究和反应技术两方面介绍了苯与长链烯烃烷基化反应技术的研究开发进展。催化剂是决定烷基化反应技术水平的一个关键因素 ,评价了氟化硅铝、分子筛、杂多酸及离子液体等催化剂的性能。在反应技术方面 ,UOP工艺比氯化法和脱氯化氢法更具竞争力 ,介绍了UOP工艺的各种改进方案。指出今后应进一步深入研究杂多酸等新型催化剂和反应精馏技术 ,包括悬浮床催化蒸馏工艺。The progress in alkylation reaction of benzene with long chain alkenes was introduced from the two aspects of catalyst research and reaction technology.Catalyst is a key factor for the alkylation reaction technology.Properties of catalysts such as fluorinated silica-alumina,molecular sieve,heteropolyacid and ionic liquid were evaluated.As to reaction technology,the UOP process is more competitive than the chlorination process and the hydrogen chloride stripping process and several improvements in the UOP process were reviewed.It was pointed out that further studies should be focused on new catalysts such as heteropolyacid,as well as reaction distillation technologies including the suspension-bed catalytic distillation (SCD) process.
