补充资料:乙酸苯酯
分子式:C8H8O2
分子量:136.15
CAS号:122-79-2

性质:无色液体。沸点195.7℃,相对密度1.0780(20/4℃),折光率1.5033,闪点76℃。能与乙醇、乙醚、氯仿和乙酸混溶,微溶于水。有强折光性(与玻璃相同),有苯酚气味。

制备方法: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。
