CAS: 40248-63-3
分子式: C12H22O3
分子量: 214.31
沸点: 113℃(0.1
熔点: 52-55℃
中文名称: 
氧基乙酸
英文名称: 
(-)-menthoxyacetic acid
Menthoxyacetic acid
性质描述: 熔点52-55℃,沸点163-164℃(1.33kPa),折光率(nD20)1.4672,相对密度1.020。
生产方法: 将400g(2.56mol)薄荷醇溶于1L甲苯,加入70g(3.04mol)金属钠,加热回流15h,除去过量的钠,滴加95g(1.01mol)氯乙酸溶于800ml甲苯的溶液,加毕,搅拌回流48h。用水提取反应混合物,提取液用20%盐酸酸化,粗品氧基乙酸即成褐色油状物积聚于上部。粗品可用减压蒸馏提纯,得产品166-180g,收率78%-84%。
用途: 用于有机合成中间体。
