摘要
本文以邻苯二甲酸酐和乙苯为原料，采用傅氏酰基化，水解，闭环，蒸馏回收溶剂，氧化还原提纯及乙醇萃取蒸馏技术，合成了高纯度2-乙基蒽醌．
he intermediate 4'-ethyl-2-pbeoylglyoxylic acid is synthesed by Friedel-Craftsacylation from ethylbenzene and phthalic anhydride, and high purity 2-ethylanthraquinoneis also synthesed by hydrolyzation, cyclization, distillation of solvent, reduction-oxidation purification and extractive distillation by ethanol.
