摘要
以2,4-二羟基二苯甲酮为原料,经醚化、酯化反应合成有机中间体2-(4-苯甲酰基-3-羟基苯氧基)丙烯酸乙酯;并对其反应的工艺条件进行研究。研究结果表明:反应温度、催化剂的用量和聚合物抑制剂对收率有明显的影响。由此得出反应的适宜条件是:反应温度为150℃;催化剂用量为1.2 g;使用聚合物抑制剂收率可达80.5%。
2-（4-Benzoyl-3-hydroxyphenoxy） ethyl acrylate was synthesized from 2,-4 dihydroxybenzophenone, ethylene carbonate and acrylate acid by etherification and esterification. The factors influencing the synthesis were discussed and the best reaction conditions were found. The optimum conditions were as follow： the reaction temperature was 150℃, catalyst loading was 1.2 g and polymerization was used as inhibitor. The total yield reaches 58.76 %.
