二苯甲醇制备
1.制法:
于装有搅拌器、温度计、回流冷凝器的1L反应瓶中,加入二苯酮(2)50g(0.275moPl),500mL(95%)的乙醇,氢氧化钠50g和锌粉50g(0.76mol),剧烈搅拌,慢慢升温至约70℃。3h后,温度降低,过滤,滤渣用热的95%的乙醇洗涤两次(剩余的锌粉不能变得干燥,以免着火)。将滤液倒入2L冰水中,用100mL浓盐酸酸化,析出白色固体。抽滤,空气中干燥,得粗产品二苯甲醇49g,mp65℃。用50mL热乙醇重结晶,并且于冰盐浴中冷却,过滤析出的无色固体,干燥,得纯品二苯甲醇①(1)36g,mp68℃。母液可回收部分产品。注:①也可用硼氢化钠于95%的乙醇中还原二苯酮来制备二苯甲醇,收率90%左右。
