| 摘 要： | 采用非均匀沉淀法制备了Al1P1.30TiaSib(a=0-0.51,b=0-0.90）复合催化剂，研究了邻苯二酚与甲醇在该催化剂上的气相o-甲基化反应。结果表明，催化剂组成、相结构和表面性质对催化剂的活性和选择性有很大影响。其中Al1P1.30Ti0.30si0.17催化剂的愈创木酚收率最高，在反应温度为553K时，邻苯二酚转化率和愈创木酚收率分别为92%和86%。

| Abstract: | Complex oxide catalysts of Al\-1P\-\{1.30\}Ti\-\%a\%Si\-\%b(a=0\_0.51, b\%=0\_0.90) were prepared by ununiform precipitation method. The vapor phase \%o\%\|methylation of catechol with methanol over the synthesised oxides was studied. The activity and selectivity of these catalysts were greatly dependent on the compositions, the phase structure and surface properties of the catalysts. Among the samples tested, Al\-1P\-\{1.30\}Ti\-\{0.30\}Si\-\{0.17\} gave the highest yield 86% for guaiacol and 92% conversion of catechol at 553 K. |
