NOVELTY - Producing mexiletine hydrochloride comprises e.g. adding 2,6-xylenol, dimethylformamide, potassium carbonate and sodium bromide into a reaction vessel, heating, adding chloroacetone dropwise and carrying out the reaction; (ii) carrying out hydrogenation process by adding ether ketone, raney nickel, in a hydrogenation kettle containing methanol, adding liquid ammonia and sealing the hydrogenation kettle; and (iii) refining and salt-forming by adding ether amine, ethyl acetate and activated carbon into the reaction vessel, decolorizing and filtering.    USE - The method is useful for producing mexiletine hydrochloride (claimed).    ADVANTAGE - The method has less reaction steps and good economic and social benefits; does not use highly toxic carcinogens; and is environmental friendly.    DETAILED DESCRIPTION - Producing mexiletine hydrochloride comprises adding 2,6-xylenol, dimethylformamide, potassium carbonate and sodium bromide into a reaction vessel, heating to 50-55 degrees C, adding chloroacetone dropwise, carrying out the reaction for 1 hour at 63-68 degrees C, then incubating for 10 hours, filtering, collecting the filtrate into a rectifying kettle, removing atmospheric fraction at 100 degrees C, controlling the vacuum less than 0.09 MPa and collecting the fraction at 100-110 degrees C, to obtain ether ketone, where the amount of raw materials used includes 75 pts. wt. 2,6-xylenol, 600 pts. wt. dimethylformamide, 4.5 pts. wt. sodium bromide, 150 pts. wt. potassium carbonate and 100 pts. wt. chloroacetone; (ii) carrying out hydrogenation process by adding ether ketone, raney nickel, in a hydrogenation kettle containing methanol, adding liquid ammonia and sealing the hydrogenation kettle, feeding 1.2 Mpa hydrogen into the kettle, carrying out the reaction at 50-55 degrees C, until the kettle is free of hydrogen to absorb, adding the reaction liquid into the concentration kettle, controlling the temperature at 80 degrees C, recycling methanol, collecting the fraction at 100-110 degrees C, to obtain ether amine, where the amount of raw materials used includes 100 pts. wt. ether ketone, 17 pts. wt. raney nickel, 350 pts. wt. methanol, 150 pts. wt. potassium carbonate and 70 pts. wt. liquid amminia; and (iii) refining and salt-forming by adding ether amine, ethyl acetate and activated carbon into the reaction vessel, decolorizing for 30 minutes, filtering and transferring the filtrate to another reactor, adding hydrochloric acid dropwise until the pH is 5.5, freezing to temperature below 5 degrees C and filtering, to obtain the final product, where the amount of raw materials used includes 80 pts. wt. ether amine, 5 pts. wt. activated carbon and 350 pts. wt. ethyl acetate.
