CAS: 498-21-5
分子式: C5H8O4
分子量: 132.12
熔点: 110-115℃
中文名称: 
焦酒石酸
甲基丁二酸
甲基琥珀酸
英文名称: 
methyl succinic acid
methyl-Butanedioic acid
Methylsuccinic acid
Pyrotartaric acid
methyl-butanedioic aci

2-Methylbutanedioic acid
Propane-1,2-dicarboxylic acid
methyl-Butanedioic acid
性质描述: 白色结晶或粉末。熔点111-112℃,相对密度1.4105。加热至200℃生成酐。溶于水,醇和醚。
生产方法: 以丁烯酸为原料,经以下步骤制得。将丁烯酸和乙醇与四氯化碳混合,添加硫酸,回流反应12h,回收乙醇和四氯化碳,并盐析得到巴豆酸乙酯。将巴豆酸乙酯、乙醇与氰化钠水溶液回流反应5h。再加入氢氧化钡溶液,经减压浓缩至粥状,冷却。加入硝酸,剧烈反应放出氰化氢气体。减压浓缩至干,用苯、乙醚提取后得粗品,最后用苯、水重结晶各一次,即得成品。
用途: 用于有机合成。
