| 摘要: |
| 在三氟化硼乙醚溶液催化下，正辛醛与环氧溴丙烷首先反应生成2-庚基- 4-溴甲基-1,3- 二氧杂环戊烷，然后再与吡啶反应，研究合成了一种新型的含吡啶环的单阳离子表面活性剂（2-庚基-1,3- 二氧杂环- 4）甲烷-1-吡啶盐。产物结构经红外光谱和1HNMR分析表征并测定其电导率，该表面活性剂的临界胶束浓度为4.0×10- 3 mol/L，表面活性强于传统表面活性剂。 |

| Abstract: |
| Catalyzed by the ether solution of boron trifluoride, n-octyl aldehyde reacted with epibromohydrin to produce 2-heptyl-4-
bromomethyl-1,3-dioxolane. Then it was reacted with pyridine, thus a new type of single cationic surfactant containing pyridine ring,
(2-heptyl-1,3-dioxane-4)-1-methane pyridine salt, was synthesized. The structure of resulting product was characterized by IR and
1HNMR. By the measurement of conductivity, the critical micelle concentration of this surfactant was 4.0×10-3 mol/L, which showed that its surface activity was stronger than that of traditional surfactants. |
