摘要
为了实现蒸煮助剂2-乙基蒽醌(2-EAQ)的合成绿色化,首次在缩合反应中,以水为溶剂,热处理过的明矾为催化剂,乙苯和苯酐为原料,制得2-(4′-乙基苯甲酰基)苯甲酸(BEA);BEA经过脱水闭环反应得到2-乙基蒽醌(2-EAQ);对BEA和2-EAQ进行定性分析.试验结果表明,合成BEA的最优反应条件是:苯酐加料速率0.12 g/min,反应温度40℃,搅拌速度520 r/min.
Green synthesis of 2-（4＇-ethylbenzoyl）-benzoic acid （BEA） was realized by the condensation reaction for the first time, with water as solvent, heat treated alum as a catalyst, ethylbenzene and phthalic an- hydride as materials. 2-ethylanthraquinone （2-EAQ） was synthesized through dehydration closed loop reac- tion. BEA and 2-EAQ were analyzed through the qualitative analysis. The optimal BEA synthesis conditions were： the feeding rate of phthalic anhydride was 0.12 g/min, reaction temperature was 40 ℃, and the stirring speed was 520 r/min.
