Determination of Dimethylaminopropylamine in Alkylaminoamides by High-Performance Liquid Chromatography

Abstract

Dimethylaminopropylamine (DMPA), a diamine which, together with salicylaldehyde, forms a Schiff base, is used as a raw material in the synthesis of aminoamides of the fat chain. These aminoamides can in turn be the basis of some compounds from the tensioactive industrial area: betaines, aminic oxides, and quaternary ammonium salts. The derivatization reaction of DMPA is optimized using reversed-phase high-performance liquid chromatography with ultraviolet detection for its determination in samples of aminoamides.
