  • 用途四:GB 2760一96规定为允许使用的食用香料。作为香料,大量用于配制香蕉、梨、菠萝、杏、桃及草莓、浆果等型香精。亦可用作天然胶和合成树脂等的溶剂。
  • 乙酸丁酯的提纯:分析上常用作溶剂、萃取剂。乙酸丁酯一般含有乙醇、乙酸和水。 乙酸丁酯的提纯方法 (1) 减压蒸馏法 乙酸丁酯用等体积碳酸钠溶液 (5%)洗涤,加入无水氯化钙干燥后蒸馏,当干燥要求严格时,可加入五氧化二磷干燥、过滤,在隔绝湿气的条件下蒸馏。也可用饱和碳酸氢钠溶液萃取洗涤两次,再用无水硫酸镁干燥后蒸馏。蒸馏装置如图1所示。 图1 乙酸丁酯减压蒸馏装置 1—水浴;2—1000 ml克莱森烧瓶; 3—毛细管; 4—温度计;0~ 100℃;5—球形冷凝管; 6—接受器; 7—加热圈; 8—接调压变压器; 9—接真空泵; a、b—两通活塞; c—三通活塞 将500ml洗涤干燥过的乙酸丁酯置于烧瓶中,联结蒸馏装置,打开活塞a、b、c,启动真空泵抽出系统内的空气,当系统内压力达到7998Pa时,接通恒温水浴电源,温度控制在60~70℃,蒸馏速度,1~2滴/s,待蒸出50~60ml后,关闭活塞a,使活塞 c接通大气,卸下接受瓶,弃去首段馏出液,装好并接通c,使接受瓶与泵接通,蒸馏继续进行,当蒸出300~350ml馏出液时停止蒸馏,此中段馏分即为提纯品。注意水浴温度应随真空度的大小而定,应以蒸馏速度为准。 (2) 乙酸丁酯的回收 将使用过乙酸丁酯废液,在分液漏斗中水洗几次,然后用硫代硫酸钠稀溶液洗涤几次使之褪色,再用水洗几次,再按(1)蒸馏提纯。
