摘要： A novel process for the preparation of benzyl alcohol by the hydrolysis of benzyl chloride, which operates with from 10 to 70 times the molar quantity of water at temperatures of from 80.degree. to 180.degree. C. and stops the reaction before complete conversion is reached, avoids both the addition of bases and water-soluble organic solvents and also the formation of sodium chloride.
摘要翻译： 通过苄基氯的水解制备苄醇的新方法，其在80至180℃的温度下以10至70倍摩尔量的水进行操作，并在完全转化之前停止反应， 避免了碱和水溶性有机溶剂的添加和氯化钠的形成。

摘要： A process for the separation of a mixture which contains benzyl chloride, benzyl alcohol, dibenzyl ether and aqueous hydrochloric acid, wherein said mixture is continuously introduced via a side-feed into a distillation column from which aqueous hydrochloric acid and benzyl chloride are continuously taken off as overhead product, benzyl alcohol and dibenzyl ether are continuously taken off as bottom product, thereby the formation of dibenzyl ether is reduced or virtually prevented.
摘要翻译： 分离含有苄基氯，苄醇，二苄醚和盐酸水溶液的混合物的方法，其中所述混合物通过副进料连续引入蒸馏塔，从其中连续除去盐酸和苄基氯水溶液 作为塔顶产物，苄醇和二苄基醚作为底部产物连续取出，从而减少或实际上防止了二苄基醚的形成。
