UTILISATION D'ANILINE APPAUVRIE EN ELECTRON POUR LIBERER DE L'ACIDE CHLORHYDRIQUE PRESENT DANS UN MELANGE REACTIONNEL ET PROCEDE POUR DEPLACER, AU MOINS PARTIELLEMENT, UNE ANILINE DE SON CHLORHYDRATE

摘要

The invention concerns a method for displacing, at least partially, an aniline from its chlorhydrate, characterized in that said aniline is selected among anilines whereof the conjugate acid has a pKa not more than 6 and in that it consists in a step wherein it is subjected at a temperature not less than 50° C., advantageously about 70° C. to a reaction medium containing said chlorhydrate at least partially dissolved in a weakly polar solvent. The invention is applicable to organic synthesis.
