摘要
研究了合成4,5-二(氯甲基)-3-羟基-2-甲基吡啶时各种因素对产率的影响,发现氯化反应采用催化剂很关键,并确定了最佳工艺条件。
When studied kinds of factors affect prouuct ratio on the synthesis of 4,5-dichloromethyl-3-hydroxyl-2-methyl pyridine. We found that it is very important to adopt the suit catalyat of the chlorination reaction. And the optimum technological factors are confirmd.
