CAS: 818-38-2
分子式: C9H16O4
分子量: 188.22
沸点: 237℃
中文名称: 
胶酸二乙酯
戊二酸二乙酯
英文名称: 
pentanedioic acid diethyl ester
Pentanedioic acid,diethyl ester
Glutaric acid diethyl ester
Pentanedioic acid, diethyl ester
Diethyl glutarate
Diethyl pentanedioate
Ethyl glutarate
性质描述: 糖浆状液体。熔点-24.1℃,沸点236.5-237℃,相对密度(20/4℃)1.0220,折光率 1.4241。溶于醇和醚,微溶于水。
生产方法: 将无水乙醇、浓硫酸、戊二腈一起回流16h,回收乙醇,剩余液放入冰水中,分出上层油状物,用10%碳酸钠溶液洗涤,再用水洗至中性。分出油层减压蒸馏,收集122-128℃(2.67kPa)馏分,得戊二酸二乙酯。收率约55%。
用途: 有机合成中间体。
