摘　　要：通过对吡啶光氯化的反应条件优化和化工控制,有效地控制了反应中的聚合, 焦油化等副反应,实现了反应的高转化率和高选择性.控制反应条件, 可以改变2-氯吡啶和2,6-二氯吡啶 两种产物的比例,使其中某一种产物为主.并用现代物理方法对主要产品之一的2-氯吡啶进行了结构分析,证实了这一合成方法的可靠性.In the reaction process through improving reaction conditions, the high transformation from the reactants into the reaction products and high selectivity of the reaction were achieved, and the polymers and tarry matters in the products were dispeled. The propeortion of 2 - chloropyridine and 2,6- dichloropyridine, the main products can be controled by changing reaction condition . The chemical composition and structure of main products were measured by modern physical method.
