Glucosamine decanoate(GAD),one kind of aliphatic carboxylate surfactant,was synthesized by decanoic acid reacted with glucosamine(GA) which was prepared by glucosamine hydrochloride(GAH) and triethylamine in ethanol-water condition.The structure of GAD was characterized by infrared spectroscopy(IR) and nitrogen elementary analysis.The surface activities of GAD were measured at 25 ℃,which showed that its critical micelle concentration(CMC) was 8.51×10-4 mol/L,its surface tension(γ CMC) corresponding to CMC was 30.1 mN/m,its saturated adsorption(Γmax) was 4.33×10-10 mol/cm2,and its saturation adsorption molecular area(Amin) was 0.38 nm2;GAD possessed certain foamability,good emulsifying ability for liquid paraffin,and good compatibility with Tween 80,dodecyl dimethyl betaine(BS-12),hexadecyl trimethyl ammonium chloride(1631) and other agents with no demixing phenomenon.
