Abstract

1, 2-Disubstituted imidazolines, such as 1-behenoyl-aminoethyl-2-heneicosylimidazoline(BHI), 1-behenoylbis(aminoethyl)-2-heneicosylimidazoline(BBI), and 1-behenoyltris(aminoethyl)-2-henoicosylimidazoline(BTI) were synthesized by reacting 3 kinds of polyalkylene polyamines with behenic acid to provide the softness to imidazoline ring.1, 2-Disubstituted imidazolinium chlorides, such as 1-behenoyl-aminoethyl-1-glycidyl-2-heneicosylimidazolinium chloride(BHIC), 1-behenoylbis(aminoethyl)-1-glycidyl-2-henoicosylimidazolinium chloride(BBIC), and 1-behenoyltris(aminoethyl)-1-glycidyl-2-henoicosylimidazolinium chloride(BTIC) were prepared by quaternizing 1, 2-disubstituted imidazoline compounds. The optimum condition for the preparation of BHI, BBI, and BTI was 8 hrs at $210^{\circ}C$. In the synthesis of BHIC, the completely quaternized product was obtained by reacting BHI-epichlorohydrin with 1:1.3 mole ratio, and mole ratios higher than 1:1.5 were required in the preparation of BBIC and BTIC, BHICS, BBICS, and BTICS softners form BHIC, BBIC, and BTIC was treated to acrylic fiber. It was found that were good softners as the softening property was measured.
