摘 要: 5-氯甲基水杨醛是一种重要的取代型水杨醛,本文直接利用水杨醛与甲醛和浓盐酸反应得到5-氯甲基水杨醛,对合成条件和粗产品的纯化方法进行了改进,提高了产率、大大减少了溶剂的使用、缩短了操作时间,提出了一种高效的纯化方法。 5 -chloromethyl salicylic aldehyde is an important substituted salicylic aldehyde. It was synthesized rectedly by salicylic aldehyde and formaldehyde and concentrated hydrochloric acid. The synthesis condition and process for the purification were improved. The yield was increased and the solvent amount was decreased largely and operation time was shorten obviously in the new synthesis method.
