| 主权项 | 1. 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, wherein the reaction is free of solvent, and said process does not involve the preparation or isolation of 2-MEPy in a solid form. | ||
