Abstract
Un procedimiento para la separación de nitrosaminas de dinitro anilinas que las contienen, aunque sea en cantidades muy pequeñas, caracterizado por hacer reaccionar la nitrosamina contenida en una dinitroanilina seleccionada enre el grupo que consiste en trifluralina, isopropalina, benefina, etalfluralina, butralina, tendimetalina, flucloralina, profluralina, dinitramina, 4-triflorometil-2,6-dinitro-3-cloro-N,N-dietilanilina, 4-metil-2,6-dinitro-N,N-bis(2-cloroetil)anilina, orizalina, y nitralina, (a) en fase líquida (b) con un reactivo seleccionado entre el grupo que consiste en ácido clorhídrico al 20-38% de HCl gaseoso, hasta que se ha reducido la concentración de la nitrosamina; y (2) recuperar posteriormente la dinitroanilina.
