Manufacturing method of the 2,6- divinyl pyridine and 2- methyl -6- vinyl pyridine from the 2,6- lutidine by the denaturation zeolite

摘要

This invention 2,6 by the denaturation zeolite catalyst - divinyl pyridine and 2 - methyl - 6 - regards the manufacturing method of vinyl pyridine. Especially this invention, in the environment which possesses high yield and selectivity with kind method, 2,6 - from the lutidine and formaldehyde, 2,6 - divinyl pyridine and 2 - methyl - 6 - regards the method of synthesizing vinyl pyridine in the vapor phase. This invention with non corrosiveness offers kind method in environment, the aforementioned catalyst is reuse possible with anything time. 2,6 - as for divinyl pyridine, it is the useful start material in polymer industry.
