摘要
以乙苯和苯酐为原料,经傅氏酰基化反应,先合成2-(4′-乙基苯甲酰基)苯甲酸中间体,再经水解,闭环,蒸馏回收溶剂,还原氧化提纯及乙醇萃取蒸馏等技术,合成了高纯度的2-乙基蔥醌.
The intermediate 4'-ethyl-2-pheoylglyoxylic acid is synthesed by FriedeI-Crafts acylation from ethylbenzene and phthalic anhydride,and high purity 2-ethylanthraquinone is also Synthesed by hydrolyzation,cyclization,distillation of solvent,reduction-oxidation purification and extractive distillation by ethanol.
