摘 要:普通松香通过丙烯酸改性,与氯化亚砜、甲醛、吡啶合成新型吡啶双季铵盐阳离子表面活性剂。确定了反应的最佳工艺条件:n(丙烯酸改性松香) ∶ n(甲醛) ∶ n(吡啶)=1 ∶ 3 ∶ 4,m(催化剂) ∶ m(反应物料)=0.04 ∶ 1,反应温度75~85℃,反应时间8 h。用红外光谱对目标产物进行了分析,测定了目标产物的表面性质。结果表明,目标产物吡啶双季铵盐阳离子表面活性剂具有良好的表面活性,并与阴离子表面活性剂有很好的相容性。

Abstract:A novel bi-pyridine quaternary ammonium salt cationic surfactants was prepared by acrylic modified rosin. The optimum conditions were determined as follows:n(acrylic modified rosin) ∶ n(formaldehyde) ∶ n(pyridine)was 1∶ 3 ∶ 4,the ratio of Catalysts to total reaction materials was 0.04 ∶ 1,reaction time was 8 h,temperature was 80℃. The product was characterized by IR. The surface properties of the product was determined. The result showed that the product had good surfactant and can compatibility with anionic surfactants.
Key words:modified rosin;acrylic;pyridine quaternary ammonium salt
