CAS: 2613-89-0
分子式: C9H8O4
分子量: 180.16
熔点: 149-152 °C (dec.)(lit.)
中文名称: 
苯丙二酸
苯吗啉酸
英文名称: 
phenyl-propanedioic aci
Phenylmalonic acid
性质描述: 棱状结晶。熔点153-155℃(分解)。溶于水、乙醇、乙醚,微溶于氯仿、二硫化碳、苯。
生产方法: 由苯丙二酸二乙酯水解而得。水解:先将无水乙醇加入反应锅中,搅拌加粒碱至全溶,冷却至45-50℃,滴加苯丙二酸二乙酯,约2-3h加完,保温2h,再冷却至10-15℃,过滤,60℃烘干,粉碎得苯丙二酸钠,收率90%。酸化:将丙酮置于反应锅内,加入苯丙二酸钠,冷却至10℃,滴加硫酸pH=1.0-0.5。过滤,滤饼用丙酮洗四次后弃去,滤液和洗液合并,用薄膜蒸发器浓缩回收丙酮至浓稠状,加甲苯于15℃结晶过滤,滤饼用甲苯洗涤,滤干,烘干,得苯丙二酸,收率76%。
用途: 该品是抗菌素类药物羧苄青霉素钠的中间体。
