摘要
采用不均匀沉淀法制备了二元组分Al1P1.3 0 ,三元组分Al1P1.3 0 Si0 .17,四元组分Al1P1.3 0 Ti0 .3 0 Si0 .17三个催化剂 ,并研究了邻苯二酚与乙醇在该催化剂上的气相O 乙基化反应 .结果表明 ,在Al1P1.3 0 Ti0 .3 0 Si0 .17催化剂上 ,邻苯二酚转化率和目的产物收率分别约为 94%和 84% ,并在反应 10 0h内保持活性不衰减 。
Vapor phase O-ethylation of catechol with ethanol was studied on threecatalysts: Al 1P 1.30, Al 1P 1.30Si 0.17 and Al 1P 1.30Ti 0.30Si 0.17, which were prepared by precipitation method. Among the samples studied, Al 1P 1.30Ti 0.30Si 0.17 had the highest conversion of catechol(94%) and yield of guathol(84%) and stabilize to 100?h.
