摘　　要：用天然硅铝酸代替传统的ＡｌＣｌ３和Ｈ２ＳＯ４等酸性催化剂用于联苯与丙烯的烷基化反应，工艺过程简单，无腐蚀，无废水污染。在ｘ（丙烯）：ｘ（联苯）为０．８：１、天然硅铝酸用量为１０％、反应温度为１７５℃的情况下反应４ｈ，联苯的转化率达５８％，单异丙基联苯的收率达４６％。A new process for alkylation of biphenyl and propene under the catalysis of natural SiO2-Al2O3 catalyst instead of traditional acid catalysts such as AlCl3 and H2SO4 is introduced.The new process is simple, non-corrosive and of no water-pollution. The conversion rate of biphenyl reached 58%and the yield of mono-isopropylbiphenyl was 46%after 4 hours reaction with the ra- tio of propene to biphenyl being 0.8:1,the concentration of natural SiO2-Al2O3,10%and the re- action temperature,175 ℃.
