一种新型吡啶Gemini表面活性剂的合成及表面活性
Synthesis and surface activity of a novel Gemini pyridinium surfactant
摘要
Abstract
The intermediate 1 ,3-di (3 -pyridyl )urea was synthesized by the reaction of 3 -aminopyridine and triphosgene. The optimized conditions for the reaction were found as follows:reaction solvent,methylene chloride;reaction time,5 h;mole ratio of 3-aminopyridine and triphosgene,5∶1. The yield is 78%. Then the intermediate reacted with bromododecane to produce a new type of Gemini pyridinium surfactant. The optimized conditions were identified as follows:reaction time,5 h;reaction temperature,110 ℃;mole ratio of the intermediate and bromododecane,1∶ 10. The yield is 90 %. The structure of the target product was characterized by FT-IR,1 H NMR,13 C NMR and ESI-MS. The surface tension of the product was measured as cmc value of 1.67 × 10 -4 mol/L and γcmc of 30.7 mN/m.关键词
