Abstract

L'invention concerne un procédé de production de N,N-di (éthyl)-méta-toluamide à partir d'acide méta-toluique par réaction catalytique en phase liquide avec la diéthylamide. L'acide méta-toluique réagit avec la diéthyhmine en phase liquide à des températures élevées en présence d'un catalyseur choisi entre le tétrachlorure de titane et certains titanates organiques pour former le N,N-diéthyl-métatoluamide. Le N,N-diéthyl-méta-toluamide est très utilisé comme ingrédient actif dans des formulations exerçant un effet de répulsion sur les insectes.
