| Abstract | TITLE: A COMMERCIAL PROCESS FOR PRODUCING HIGHLY PURE NICOTINAMIDE. The invention relates to a commercial process for producing highly pure nicotinamide, comprising reacting 3 – cyanopyridine with water in the presence of a base at a 3 – cyanopyridine concentration of about 20 to about 85 weight percent to form a reacted medium containing about 20 to about 85 weight percent nicotinamide, and a nicotinic acid salt; the steps of treating the reacted medium with a cation exchange resin to remove cations land thereby convert said nicotinic acid salt to nicotinic acid, resulting in a cation – depleted aqueous medium containing about 20 to about 85 weight percent nicotinamide, and nicotinic acid; treating the cation-depleted medium with a weak base resin to remove nicotinic acid, resulting in a nicotinic acid – depleted aqueous medium containing about 20 to about 85 weight percent nicotinamide; and isolating said nicotinamide in USP grade by evaporation.
