新方法合成2—氯—5—三氯甲基吡啶

Synthesis of 2-chloro-5-Trichloromethylpyridine with New Method

改进了传统的气相法生产2-氯-5-三氯甲基吡啶,以较新颖的液相合成方法成功地合成出2-氯-5-三氯甲基吡啶。提高了产率,减少了反应时间,且条件较为温和,在化工生产中具有一定的指导意义,对于其他吡啶类化合物的氯化亦有一定的参考价值。

A new method was described for liquid phase synthesis of 2-chloro-5-trichloropyridine which improved the traditional method of gas phase. This method increased the yield rate and reduced the reaction time. It had significance both in the chemical production and chlorination of other pyridine compounds.
