Abstract: A process for selectively converting n-paraffins to secondary alkyl primary amines where byproduct formation is substantially reduced which comprises contacting the n-paraffin in a plurality of reaction zones with a nitrating agent, removing gaseous reaction products and water from the liquid products of each of the reaction zones and introducing nitrating agent along with liquid product from the preceding zone into each succeeding reaction zone, thereby effecting an overall conversion to nitroparaffin not exceeding 25 weight percent of the n-paraffin, and thereafter hydrogenating the nitroparaffin to the amine.

Abstract: This invention concerns the separation and purification of secondary alkyl primary amines from mixtures comprising major amounts of contaminants, through the formation of secondary alkyl primary amine-carbon dioxide complexes which are preferentially extracted by inert solvents which are immiscible or partially immiscible with said mixtures and have poor solubility for the contaminants contained therein.
