Process for the preparation of nicotinic acid |
| abstract |
A method for the production of nicotinic acid (I) involves spray-drying an aqueous solution of ammonium nicotinate to form (I) followed by thermal treatment in a fluidized bed at 100-200 (preferably 130-170) degrees C or under reduced pressure (preferably at below 50 mbar) at 70-150 (preferably 80-120) degrees C. |
