Abstract

"PROCESSO PARA REMOçãO POR DESTILAçãO DE 6-AMINOCAPRONITRILA". Esta invenção é relacionada a um método para separar 6-aminocapronitrila de misturas (I) contendo 6-aminocapronitrila e uma imina (II) por destilação. O referido método é caracterizado em que a destilação ocorre na presença de dióxido de carbono."PROCESS FOR REMOVAL BY DISTILLATION OF 6-AMINOCAPRONITRILLA". This invention relates to a method for separating 6-aminocapronitrile from mixtures (I) containing 6-aminocapronitrile and an imine (II) by distillation. Said method is characterized in that the distillation occurs in the presence of carbon dioxide.
