| Abstract: | dichloropyridine was selectively synthesized with pyridine by UV light chloronation reaction. The conditions of the reaction were optimized: the ratio of pyridine to chlorine is 1:2.3,the reaction temperature is 200℃ while the reaction time is five hours and the conversion is 95.7% at this conditions. The obtained products were characterized by IR,GC-MS and EA. |
