| titleOfInvention | METHOD FOR PRODUCING 2,3-DIFLUOR-6-NITROPHENOL. |
| abstract | According to a process for the production of 2,3-difluor-6-nitrophenol free of isomers, 2,3,4-trifluornitrobenzol is reacted with an aqueous solution of a metal hydroxide of an alkali or alkaline earth metal, in the absence of organic solvent, at temperatures between 20 ° C and 100 ° C approximately, the pH of the reaction mixture is adjusted to a value between 1 and 6 approximately by adding an acid, the product is distilled as well obtained by steam entrainment and 2,3-difluor-6-nitrophenol is isolated, after cooling. Organic solvents are not used during any stage of the process. |
