摘要
试探了一种以水为反应介质合成苯丁烯酮的新方法 .在近临界水中 ,以苯甲醛和丙酮为原料 ,在不外加任何催化剂、反应温度为 2 6 0℃、反应时间为 6h的条件下 ,苯丁烯酮的产率可达 4 6 .2 % .该新方法避免了盐类副产物的产生 。
A new method for the synthesis of benzylidene acetone with near-critical water as reaction media was developed. The yield of benzylidene acetone was up to 46.2% after 6 h's reaction at 260degreesC in the absence of any catalyst. By using this new process the problems associated with neutralizing of base after reaction and disposal of salt (common to the traditional syntheses) can be avoided.
