补充资料:苯乙基酯
分子式:C15H20O4
分子量:264.32
CAS号:76-67-5

性质: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。

制备方法: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。
