Palm fatty acids and deta(diethylene triamine)based imidazolinium softners and their characterization

摘要

Imidazolinium surfactants are the cationic surfactants,having softening and antistatic properties and are characterized by two long hydrophobic alkyl chain in the molecules.In the present study,diethylene triamine(DETA)was added to palm fatty acids in 1:2 molar ratio and the resultant mixture was heated at 150 deg C for 6 h to obtain diamidoamine.The resulting diamidoamine was subjected to dehydration under vaccum to obtain imidazoline.The recovered imidazoline was then alkylated with dimethyl sulfate(DMS)in 1:2 molar ratio to recover quaternized imidazolinium salt.Imidazoline and quaternized imidazoline were characterized using modern instrumental techniques such as FT-IR,~(13)C-NMR,~1H-NMR.
