摘要: 苯酚与乙酸酐在含有机结构导向剂的TS-1分子筛(TS-1-U)的催化下生成乙酸苯酯。通过对反应条件的考察得到,在苯酚与乙酸酐摩尔比为1:1.2,催化剂质量分数为6%,反应温度为70℃的条件下反应2.5h时,苯酚转化率可达96.5%,没有副产物生成。并且,尽管催化剂TS-1-U活性有所降低是难以避免的,但仍可以循环利用至少4次。

Abstract: In this article, phenyl acetate was synthesized from phenol and acetic anhydride over titanium silicalite-1, in which the organic structure-directing agents were immobilized (TS-1-U). The reaction conditions were specified at a phenol to acetic anhydride molar ratio of 1:1.2, a catalyst dosage of 6 m%, and a reaction temperature of 70 ℃. A total of 96.5% of phenol was converted to phenyl acetate without producing any byproducts after 2.5 h of reaction. Besides, although the catalyst deactivation is inevitable, TS-1-U could be recycled for at least four times.
