摘　　要：以单质碘为催化剂直接由苄醇催化脱水生产苄醚．考察了影响收率的因素．其最佳条件为：苄醇：催化剂：带水剂=2mol：1．2g：40ml。反应在回流温度下进行(158～160℃)。反应时间4h。产率91．2％．Synthesized of benzyl oxide was using iodine catalyst dehydration for benzyl alcohol. The factors affecting the condensation yield were investigated. The results showed that the optimum conditions are as follows: benzyl alcohol : catalyst Iodine : dehydrating agent,2mol : 1. 2g : 40mL; reaction temperature, reflux temperature; reaction time 4h. The yield is above 91. 2%
