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 |
