CAS: 1190-39-2
分子式: C11H20O4
分子量: 216.27
沸点: 251°C
中文名称: 
丙二酸二丁酯
丙二酸丁酯
英文名称: 
Dibutyl malonate
propanedioic acid dibutyl ester
malonic acid dibutyl ester
性质描述: 无色液体。熔点-83℃,沸点251-252℃,137℃(1.86kPa),相对密度0.9824(20/4℃),折射率1.4162,闪点88℃。溶于乙醇、乙醚、丙酮、苯、醋酸等有机溶剂,不溶于水。
生产方法: 丙二酸钠与丁醇在硫酸存在下经酯化反应生成丙二酸二丁酯,再经中和、水洗、蒸馏等精制过程成为成品。丙二酸钠则由氯乙酸氰化后水解制得,工艺与丙二酸二甲酯同。原料消耗定额:氯乙酸(>95%)500kg/t、氰化钠270kg/t、丁醇860kg/t。
用途: 有机合成原料,在医药工业中用于合成磺胺-6-甲氧基嘧啶等药物。
