CAS: 7322-88-5
分子式: C8H10O4
分子量: 194.190
熔点: 98-101℃
中文名称: 
乙酰基扁桃酸
α-乙酰氧基苯乙酸
英文名称: 
(S)-(+)-α-Acetoxyphenylacetic acid
(+)-O-Acetyl-L-mandelic acid
(S)-(+)-alpha-Acetoxyphenylacetic Acid
O-Acetylmandelic acid
Acetyl-hydroxyphenylacetic acid
(S)-(+)-o-acetylmandelic acid
性质描述: 熔点94-96℃。
生产方法: 扁桃酸乙酰化取新干燥好的扁桃酸1份,在干燥回流装置中加乙酰氯1.4份,在室温反应30min,再升温至55-60℃反应30min,反应时放出产生的氯化氢气体。反应结束,升温至60-65℃减压蒸馏回收过量的乙酰氯,约可得到相当于1.29倍量扁桃酸的乙酰基扁桃酸。
用途: 医药中间体。
