活性白土负载型固体酸催化剂催化酯化性能研究

The Research on Catalytic Esterification of Actived-clay Supported Solid-acid Catalyst

以蒙脱土为原料,经不同浓度的酸浸渍,得活性白土,再用不同质量百分数的Lewis和磷钨杂多酸(PW12)溶液对活性白土进行负载,得到Lewis酸/活性白土催化剂和PW12/活性白土催化剂.研究这些催化剂用于乙酸正丁酯合成时的催化活性.

Actived- clay was prepared in the process in which Montmorillonite as materious was impregnation with acid of different concentrations, then carries Lewis acid and heteropoly acid （PW12） with quality of different percentages to produce actived - clay supported solid - acid catalyst. This paper analyses catalytic activity which shows in the synthesis of n - Butyl Acetate.
