摘要
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.
