12-3(OH)-12型表面活性剂 ADAC 的合成及性能研究
Synthesis and performance of 12 - 3(OH)- 12 type surfactant ADAC
摘要
Abstract
A kind of hydroxyl propyl Gemini ammonium chloride cationic surfactant,1,3 - bis (alkyldimethylammonium chloride) isopropanol (ADAC) was synthesized with dodecyl dimethyl amine (12DMA)as main starting material under acidic condition. The purity of ADAC in the product reaches 98. 63%,which was determinated by methylene blue back titration method,and its melting point is 70. 7 ~71. 2 ℃. The chemical structure of the product was characterized by means of FT - IR and 1 H NMR. Based on single factor experiments,the optimum conditions were obtained using response surface methodology as:reaction temperature,91 ℃;reaction time,11 h;solvent,isopropanol;n(12DMA)∶ n(hydrochloric acid)=2. 03∶ 1;stirrer rotation speed,250 r/ min. Under the aforesaid conditions,the reaction yield of ADAC achieves 93. 37% . Surface performance of the target product at 15 ℃ was measured as:cmc,4. 5 × 10 - 5 mol/ L;γcmc , 27. 07 mN/ m;effectiveness (πcmc ),45. 99 mN/ m;efficiency (pc 20 ),5. 301.关键词
