摘要
将微波技术引入到以氯化苄和碳酸钠为原料的苯甲醇合成工艺中。以催化剂种类、催化剂用量、微波功率和反应时间等因素为主要工艺条件进行了研究。结果表明,优化的工艺条件为将40 mL氯化苄(≥99.5%,质量分数)和150 mL碳酸钠水溶液(30%,质量分数)混合均匀进行水解反应,催化剂A用量3.0 g,微波功率450 W,反应时间22 min,目标产物苯甲醇收率可达90%以上。相比传统的加热水解工艺,在微波场中苯甲醇的水解合成工艺有明显的改善。
In this paper, the microwave technology will be introduced to the benzyl chloride and sodium carbonate as raw materials of benzyl alcohol synthesis process. The types of catalysts, the amount of catalyst, the microwave power and reaction time and other factors as the main technical conditions were studied. To 40 mL benzyl chloride （≥99.5% ,mass fraction） and 150 mL solution of sodium carbonate （30% ,mass fraction） mixed evenly to hydrolysis, and optimize the process conditions for the amount of catalyst A 3.0 g,microwave power 450 W, reaction time 22 min, the yield of benzyl alcohol is over 90%. The results show that, compared t＇o traditional heating hydrolysis process, in the microwave field in the hydrolysis of benzyl alcohol synthesis technology have significandy improved.
