Processes for Preparing N-Ethyl-2-Methylpyridinium Bromide and N-Ethyl-3-Methyl-Pyridinium Bromide

摘要

Abstract: A process for preparing an aqueous solution of N-ethyl-2 methylpyridinium bromide (2-MEPy), comprising reacting 2 picoline and ethyl bromide in a pressure reactor at a temperature above the melting point of the reaction mixture, combining the reaction product with water, wherein said reaction product consists essentially of 2-MEPy in a liquid form, and recovering an aqueous solution of 2-MEPy.
