Acetylation between alcohol and benzoyl oxide was carried out using ZnBr_2 as a Lewisacidcatalyst in solvent-free condition. Some structures were characterized by NMR and IR.
以溴化锌为催化剂，在无溶剂条件下实现了醇与苯甲酸酐的酰化反应，部分产物经NMR和IR表征。

IR pattern indicated that Lewisacid centers mainly exist on the catalyst surface.
红外光谱测试结果表明，催化剂表面主要存在L酸中心。
