The nicotinamide thus obtained is free of nicotinic acid and can be further purified by recrystallizing from suitable solvents and/or treatments with activated carbon or activated clays.
A preferred method of obtaining pure nicotinamide is to dissolve crude nicotinamide containing nicotinic acid in hot ethyl acetate and then passing in gaseous ammonia at 60-70 C. to form insoluble ammonium nicotinate followed by removal of the ammonium nicotinate by filtration. The filtrate or liquid portion thus obtained is treated with activated carbon and activated clayat the boiling point to decolorize the solution and to remove trace impurities.
