摘要
Abstract
Cationic Gemini surfactants N,N′ - p - xylylene - bis - (dodecyldimethylammonium chloride) (XBDDMA)were synthesized by 1,4 - bis -(chloromethyl)- benzene (XDC)and dimethyldodecylamine. The chemical structure of the purified product was confirmed by FT - IR,1 H NMR and 13 C NMR. The XBDDMA and AEO9 were blended with different molar ratio,as well as the critical micellar concentration (cmc),equilibrium surface tension (γcmc )and dynamic surface tension of the blend system were studied. The results showed that as n(XBDDMA)∶ n(AEO 9 )is at the range of 1∶ 9 - 9∶ 1,following the increase of content of XBDDMA,the cmc of the blend system decreases firstly and then increases,while the area occupied by the surfactant (A min )decreases continuously. When n(XBDDMA)∶ n(AEO 9 )= 1∶ 1,the cmc of the blend system is the smallest,which is 2. 27 × 10 - 6 mol/ L,and the γcmc is 33. 06 mN/ m,which is also the smallest. The addition of XBDDMA reduces the initial diffusion energy,which reduces the dynamic surface activity of AEO 9 , and there is no synergism effect on the dynamic surface activity between XBDDMA and AEO9 .关键词
