摘要
以邻苯二酚为原料,首先合成中间体邻乙氧基苯酚,然后以十六烷基三乙基溴化铵为相转移催化剂合成了乙基香兰素,考察了相转移催化剂的选择及反应温度,最后收率为55.2%。
Ethyl vanillin was synthesized by the phase - transfer catalysis CTEAB and O - ethoxyphenol, which was prepared from pyroeatehol with an overall yield of 55.2 %, and the factors in the reaction, such as phase - transfer catalysis and temperature, were discussed.
