Process for the preparation of 5-fluoro-2-nitrobenzoic acid |
| abstract |
5-Fluoro-2-nitrobenzoic acid having low contents of 3-fluoro-2-nitro-benzoic acid is prepared in a simple manner by nitrating 3-fluorobenzoic acid in an anhydrous medium using an anhydrous nitrating acid and isolating and purifying 5-fluoro-2nitro-benzoic acid, by taking 7.5 to 15 parts by weight of water, based on 1 part by weight of 3-fluorobenzoic acid used, introducing the reaction mixture reacted to exhaustion into this volume of water taken, filtering off the precipitate formed and washing it with water. |
