化合物描述
Phenyl acetate is the ester of phenol and acetic acid. One way that it can be produced by decarboxylation of aspirin. Another way that it can be produced is by reacting phenol with acetic anhydride.
Phenyl acetate can be separated into phenol and an acetate salt, via saponification: heating the phenyl acetate with a strong base, such as sodium hydroxide, will produce phenol and sodium acetate. The two chemicals can then be separated by heat and decantation or heat and filtration.

生产方法及用途
122-79-2乙酸苯酯, 99%
生产方法
由苯酚钠与乙酐反应而得。将苯酚加入15%的氢氧化钠溶液中,搅拌溶解配制成酚钠溶液,加入乙酐,于30-40℃反应。所得的反应产物依次用水、5%氢氧化钠溶液、水洗涤,经氯化钙干燥后,蒸馏而得成品。此法所需的反应时间很短,收率约77%。另一种操作方法是将苯酚和乙酐一起加热至沸,回流3h,冷却后依次进行水洗、碱洗、水洗,经无水硫酸钠干燥后,蒸馏收集190-195℃馏分,好为乙酸苯酯。收率约83%。
用途
用作溶剂和有机合成的中间体,乙酸苯酯经转位反应得到羟苯乙酮,用于治疗急慢性黄疸型肝炎、胆囊炎
