合成2-乙基蒽醌的新方法
摘要:
报道了以柠檬酸改性的H-Beta沸石分子筛为催化剂,2-(4'-乙基苯甲酰基)苯甲酸(BE酸)脱水合成2-乙基蒽醌(2-EAQ)的新工艺,并对反应条件进行了优化。在优化的条件下,BE酸的转化率为99.5%,2-乙基蒽醌的选择性可达99.0%。

A Highly Effective Method for the Synthesis of 2-Ethylanthraquinone
Abstract:
The dehydration of 2-(4'-ethylbenzoyl) benzoic acid(BE acid) into 2-ethylanthraquinone(2-EAQ) was investigated over H-Beta catalyst modified by citric acid.Different feed-in methods and the reaction conditions were studied in detail.Under optimized conditions,the conversion of BE acid could reach 99.5%,and the selectivity to 2-EAQ was up to 99.0%.The results show that the H-Beta zeolite can be considered as an efficient catalyst for the substitute of concentrate H2SO4 or oleum catalyst for the dehydration of BE acid to 2-ethylanthraquinone.
