【摘要】 采用相转移催化剂,由对氯苄叉二氯水解制备对氯苯甲醛。选择了适宜的相转移催化剂,考察了催化剂用量、用水量和反应温度等因素对水解反应速率的影响,确定了适宜的水解反应工艺条件,对氯苯甲醛的收率达到99%。更多还原

【Abstract】 p - chlorobenzaldehyde was prepared by phase - transfer catalytic hydrolysis of p -chlorodichlorotoluene. The appropriate PTC was chosen and the effect of amount of catalyst, ratio of water to p - chlorodichlorotoluene and temperature on reaction rate were studied. The optimal condition of hydrolysis , reaction was decided. The highest yield of p - chlorobenzaldehydeis 99 % .更多还原
