Processes for producing highly pure nicotinamide |
| abstract |
Described are processes for the large, commercial scale production of USP grade nicotinamide, wherein the USP grade product is isolated using novel strategies which minimize product waste, and avoid the need for crystallizations and/or ameliorate complications arising in crystallization strategies. Preferred processes involve the processing of nicotinamide reaction crudes over both cation exchange and weak base resins and the subsequent recovery of USP grade nicotinamide by simple evaporation. |
