摘　　要：研究HMCM-56分子筛上苯酚与异丙醇烷基化反应,探讨了反应条件包括温度,原料配比,催化剂的装填量,空速对催化剂催化性能的影响.通过X射线衍射、研究催化剂的酸性及晶相.得到最佳反应条件:T=220℃,WHSV=3.0h-1,Catalyst Loading=0.3 g,n(IPA)/n(Phenol)=0.8,苯酚的转化率可达75%,邻异丙基苯酚和对异丙基苯酚的总选择性为65%.Alkylation of phenol with isopropanol was camed out in HMCM -56 molecular sieves catalyst. The effects of various reaction parameters such as reaction temperature, reactant ratio （ molar ratio of isopropanoll to phenol）, catalyst loading and space velocity on catalyst performance were discussed. Employing analytical and spectroscopic techniques XRD showed a HMCM -56 structure with highly ordered crystalline structure. Optimal reaction conditions ： T = 220 ℃ ,WHSV = 3.0 h^-1 , catalyst loading = 0.3 g, nIPA/nphenol=0.8, phenol conversion rate of 75% ,the total of selectivity O -isopropyl phenol and isopropyl phenol was 65% .
