| Abstract: | 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. |
