CAS: 80-69-3
分子式: C3H4O5
分子量: 120.06
沸点: 471.4ºC at 760 mmHg
熔点: 158℃
中文名称: 
羟基丙二酸
丙醇二酸
亚酒石酸
酒石裔酸
英文名称: 
Hydroxypropanedioic acid
tartronic acid
Hydroxymalonic acid
性质描述: 无色棱状结晶。一般含1分子结晶水,在60℃时失去结晶水,110℃时升华。熔点141-142℃,156-158℃(快速加热)。易溶于水、醇,无水物能溶于醚,含结晶水的难溶于醚。
生产方法: 以丙二酸二乙酯为原料,先在光照下加溴,减压蒸馏得到溴化丙二酯二乙酯。然后加氢氧化钾溶液,加热回流4h水解,用乙酸中和至pH为5。加氯化钡溶液,生成羟基丙二酸钡盐。酸化后减压蒸馏,用乙醚提取,最后用乙酸精制而得成品。
用途: 用于有机合成。
