Abstract
The present invention relates to a process for the preparation of 2,6-divinylpyridine and 2-methyl-6-vinylpyridine over modified zeolite catalysts. In particular, it relates to the method for the synthesis of 2,6-divinylpyridine and 2-methyl-6-vinylpyridine from 2,6-lutidine and formaldehyde in vapour phase in an eco-friendly method with high yield and selectivity. This invention provides a non-corrosive, eco-friendly process, where the catalyst can be reused for many times. 2,6-Divinylpyridine is useful stating material in polymer industry.
