摘要： 以十二胺和二氯乙酸为原料合成十二胺基氯乙酸钠(DSC)。粗产品十二胺基氯乙酸(DCA)的较佳合成工艺条件为:n(二氯乙酸)∶n(十二胺)=1∶1.5,催化剂用量为1%,于120 ℃下反应18 h,产率为58.91%。对目标产物DSC采用IR进行结构表征,由表面活性分析可知其cmc为3.38×10-3 mol·L-1,γcmc为27.43 mN·m-1,通过吸光度及粒径分析得到对水溶性油墨色浆分散性较好时其用量为1.6%。

Abstract: Dodecylamine sodium chloroacetate (DSC) was synthesized from dodecylamine and dichloroacetic acid as starting materials.The first step product is dodecylamine chloroacetic acid (DCA).Optimum reaction conditions for preparing DCA were determined as:mole ratio of dichloroacetic acid to dodecylamine 1∶1.5;mass fraction of the catalyst 1%;reaction time 18 h at 120 ℃.The DCA yield achieves 58.91%.Structure of the final product DSC was characterized by IR.The measurement results for surface activities of the final product showed that critical micelle concentration (cmc) of DSC achieves 3.38×10-3 mol·L-1 and lowest surface tension (γcmc) of DSC achieves 27.43 mN·m-1.The dispersing property of DSC was identified by UV-vis and ZetaPALS,and the optimum mass fraction of DSC as dispersant in water-based printing ink is 1.6%.

Key words: dodecylamine sodium chloroacetate, synthesis, water-based printing ink, dispersant
