CAS: 76-67-5
分子式: C15H20O4
分子量: 264.32
沸点: 169℃(15
熔点: -7 °C
中文名称: 
苯基乙基丙二酸二乙酯

Diethyl ethylphenylmalonate
性质描述: 无色或微黄色透明油状液体。沸点170℃(2.53kPa),相对密度1.071(20/4℃),折射率1.4896(25℃)。溶于乙醇、乙醚,不溶于水。有异臭。
生产方法: 1.由苯基丙二酸二乙酯经乙基化而得。2.氰化苄与乙醇在硫酸存在下反应生成苯乙酸乙酯。所得苯乙酸乙酯经精馏后与草酸二乙酯及乙醇钠进行缩合反应,经盐酸酸析后再用溴乙烷进行乙基化反应,生成苯基乙基丙二酸二乙酯,最后经减压分馏精制得成品。另一种生产方法是由苯乙酸乙酯与碳酸二乙酯、溴乙烷缩合。
用途: 有机合成原料,用作苯巴比妥、扑痫酮等药物的中间体。
