CAS: 607-81-8
分子式: C14H18O4
分子量: 250.29
沸点: 162-163 °C10 mm Hg(lit.)
中文名称: 
二乙基苄基马来酸酯
苄基丙二酸二乙酯
英文名称: 
(phenylmethyl)-propanedioic aci diethyl ester
Diethyl benzylmalonate
benzyl-propanedioic acid diethyl ester
Benzylmalonic acid diethyl ester
性质描述: 无色液体。沸点162-163℃(1.33kPa),相对密度1.064,折光率(nD20)1.4860。
生产方法: 将氯苄、丙二酸二乙互、K3PO4·7H2O、三丁基苄基溴化铵按配料比投入反应器,于65℃搅拌反应5h。冷却,加入蒸馏水溶解无机盐,分出有机相,以无水碳酸钾干燥。减压蒸馏,收集142-145℃(1.2kPa)馏分,得苄基丙二酸二乙酯。收率82%。
用途: 局部麻醉药普罗帕酮(Propafenone)的中间体。
