Abstract

Inventia se refera la un procedeu pentru prepararea a 2-metil-6-trifluormetilanilinei prin tratarea 2-amino-3-trifluormetilbenzilsulfoxidului de alchil inferior cu acid halogenhidric, în mediu de solvent inert ales dintre etilendiclorura, metilenclorura, tetraclorura de carbon, toluen, xilen, clorbenzen, cloroform, tricloretilena, la temperaturi cuprinse între 60...65 degree C, obtinîndu-se 2-amino-3-trifluormetil-benzilhalogenura care reactioneaza cu o trialchilamina, în mediu de alcanol inferior, latemperatura de fierbere, pentru a forma sarea cuaternara de amoniu care se supune hidrogenarii catalitice.
