Chu, Zonglin,Feng, Yujun
, p. 2655 - 2658 (2009)
A series of novel, ultra-long-chain amidosulfobetaine surfactants were prepared by amidation of ultra-long-chain fatty acids directly with N,N-dimethyl-1,3-propanediamine in the absence of solvents, followed by quaternization of the intermediates with 1,3-propanesultone in ethyl acetate.

Unusual pH-responsive fluid based on a simple tertiary amine surfactant: The formation of vesicles and wormlike micelles

, p. 51519 - 51527 (2014)
A novel pH-responsive viscoelastic micellar system was prepared by N,N-dimethyl oleoaminde-propylamine without the addition of hydrotropes. The micellar system undergoes a gradual transition from vesicles to spherical micelles to wormlike micelles by adding an HCl solution. Rheology, Cryo-TEM and dynamic light scattering (DLS) results revealed that the pH-responsive flow behavior is attributed to the microstructural transition among the spherical micelles, vesicles and worm-like micelles. In this paper, we found out that a vesicle is extremely pH sensitive because the degree of protonation and the concentration of Cl- strongly affect the pH areas which could form worm-like micelles. The notable advantages of vesicles and worm-like micelles can be utilized to prepare pH-responsive viscoelastic fluids in the desired pH areas. This journal is

Effect of large spacer on surface activity, thermal, and rheological properties of novel amido-amine cationic gemini surfactants
Shakil Hussain,Kamal, Muhammad Shahzad
, p. 1131 - 1137 (2017/08/08)
Three new amido-amine cationic gemini surfactants comprising large spacer groups were synthesized by amidation of carboxylic acids with 3-(dimethylamino)-1-propylamine and subsequent reaction with dibromoalkane. The structures of gemini surfactants were elucidated by NMR, IR, and elemental techniques. Thermogravimetric analysis results showed impressive short-range thermal stability with no structure decomposition up to 260?°C. The structural characterization technique exhibited excellent long-range thermal stability with the survival of original structure of the gemini surfactants after aging them up to 90?°C for ten days. The critical micelle concentration readings were ranged from 0.094?mmol/L to 0.15?mmol/L and the analogous surface tension (γcmc) values were ranged from 34.12?mN/m to 36.47?mN/m. The rheological investigation was done to examine the interactions between cationic polyacrylamide and cationic gemini surfactants. The polymer viscosity and storage modulus were reduced upon addition of gemini surfactants at low shear rate because of charge screening and polymer-surfactant interactions. The gemini surfactants revealed excellent thermal and surface properties and the investigated surfactant-polymer hybrid material found to be an excellent candidate of high-temperature carbonate reservoir in which anionic surfactants are avoided because of high adsorption.
