Determination of
Dimethylaminopropylamine in Alkylaminoamides by High-Performance
Liquid Chromatography
M.C. Prieto-Blanco, P.
López-Mahía, and D. Prada Rodríguez
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.
