Abstract:
An effective improvement was studied to increase the reaction conversion to 74% by crystallization at low temperature due to the fact that there existed the main problems in twice distillation refining technique of 2-chlor-5- Chlormethylpyridine. The results indicated that the reaction conversion increased by 7% compared with the original technology, and meanwhile reduced the production cost ：The new method had an obvious economic and social benefits, and was worthy of extensions and applications.[著者文摘]
