IMPROVED PROCESS FOR THE PRODUCTION OF 2-VINYL PYRIDINE AND 4-VINYL PYRIDINE

摘要

The present invention provides an improved process for the production of 2-vinyl pyridine and 4-vinyl pyridine by reacting 2-methyl pyridine and 4-methyl pyridine respectively with formaldehyde, to form corresponding 2-pyridyl ethanol and 4- pyridyl ethanol followed by subsequent dehydration to give the title product.
