摘要
利用环氧氯丙烷和三乙胺分别与壬基酚、壬基酚聚氧乙烯醚 (n =4)反应 ,合成了 (2 -羟基 -3 -壬苯基 )丙基三乙基氯化铵 (1)和 (2 -羟基 -3 -壬苯基聚氧乙烯基 )丙基三乙基氯化铵 (2 )新型阳离子表面活性剂。化合物 (1)和 (2 )的γcmc 分别为 3 1 2 0mN/m、 3 3 47mN/m ,cmc分别为3 16× 10 -4mol/dm3 和 2 0 3× 10 -4mol/dm3 ,具有良好的絮凝能力。
The new cationic surfactants (2-hydroxyl-3-nonyl phenyl)propyl triethyl ammonium chloride(1)and (2-hydroxyl-3-nonylphenetyl)propy l triecyl ammonium chloride(2)were synthesized with epichlorohydrin,triethylamin e an d nonylphenol,nonylphenol polyoxyethlene ether in isopropanol,respectively.The r eaction temperature was between 82 ℃ ±2 ℃,the molar ratio of nonylphenol(n onylphenol polyoxyethlene ether),epichlorohydrin,triethylamine was 1∶1 2∶1 2 . The γ cmc of compounds(1)and(2) aq.were 31 20 mN/m?33 47 mN/m,cmc of th em were 3 16×10 -4 mol/dm 3 and 2 03×10 -4 mol/dm 3,respective ly.The decontamination of them were better.
