| titleOfInvention | Process for the catalyst-free production of alkoxybenzonitriles |
| abstract | A process is claimed for the catalyst-free preparation of alkoxybenzonitriles by substitution of monohalogenated starting compounds of the general formula I DOLLAR F1 in which X is Cl or Br and Y = alkyl or aryl, and is characterized in that the starting compound and an alcoholate of the general formula Z-OAlk , in which Z = Na · + · or K · + · and Alk = C¶1¶- to C¶4¶-alkyl, are kept at the final temperature for 2 to 10 hours after heating to 90 to 250 ° C., then the reaction mixture is cooled to room temperature, stirred after adding water and finally the end product is separated off. With this process, for which chlorinated and / or brominated benzonitriles are preferably used as the starting compound in the 2- or 4-position and sodium methylate or sodium ethylate as the alcoholates, the respective end products can be produced economically and at the same time in an environmentally friendly manner in very good yields and at very low cost high purity. |
