“…The surface tension of CTAB/RCOONa (RCOOK) mixed system and single component were measured by the drop volume method at 25°C under atmospheric pressure, and the surface tension‐concentration logarithm ( γ ~ lg c ) curve was plotted (Li et al, 2017; Zheng et al, 2016). The values of cmc were determined from the γ ~ lg c turning point, the surface chemical parameters and interaction parameters were calculated.…”

The interaction between novel saponification products (RCOONa or RCOOK) of Robinia pseudoacacia seed oil and cetyltrimethyl ammonium bromide (CTAB) in aqueous solution have been investigated by surface tension method at 25°C. The critical micelle concentration (cmc) of RCOONa/CTAB and RCOOK/CTAB mixture were measured. The surface properties of saponification products, CTAB as well as the mixed system were explored and compared. The composition, activity coefficient of mixed micelle, and the interaction parameters (βσ, βM) between surfactants were estimated according to the Regular Solution Theory, the Clint's model and the Rubingh's model in the framework of pseudophase separation model. The experimental results suggested that both RCOONa and RCOOK have synergism with CTAB in mixed micelle formation and surface tension reduction through calculating of βσ and βM in the mixed system. This could be attributed to the strong interaction between the head groups with opposite charges in the surfactant molecules.

Oil is a non-renewable resource, and it is essential to improve oil recovery. Surfactant flooding is a key technology in enhancing oil recovery. The present work aims to develop a new surfactant to the combination flooding system in oil displacement. The Aminosulfonic Acid Gemini Surfactant was prepared by using Hexadecylamine, 1-Butanaminium,N,N,N-tributyl-,bromide (1:1) and Sodium 2-chloroethyl sulfonate. The AminoSulfonic Acid Gemini Surfactant Sodium N,N'-Dihexadecyl-2-propanol-1,3-ethylsulfonate SNNDPE) has better reaction temperature at 80℃. The best reaction time of SNNDPE is 12 h. Next, We made a characterization of SNNDPE. A new gemini surfactant was developed, which is beneficial to the research of material science. Then the performance of the new Gemini surfactant was tested. The surface tension tests suggested that the newly synthesized Aminosulfonic Acid Gemini Surfactant has higher surface activity. The resistance temperature of the Aminosulfonic Acid Gemini Surfactant solution is 80℃. Moreover, the oil-water interfacial tension experiment suggested that the minimum aqueous solution of the combination flooding system reaches an ultra-low level of 9.4 × 10 -4 mN/m. The combination flooding system experiment results can be considered as a guidance in the design and studies of the combination flooding system for a selective.

“…Double quaternary ammonium surfactant is the most important cationic gemini surfactant, which has a simple molecular structure, low critical micelle concentration, good emulsifying property and solubilizing performance, etc. , Nonionic gemini surfactants mainly include two types: polyoxyethylene ether type or polypropylene ether type, which have the advantages of strong salt resistance, low critical micelle concentration, and good resistance to multivalent cations. In addition, related research of amphiphilic gemini surfactants has been mainly focused on the study of anionic–cationic and anionic–nonionic gemini surfactants in the past few years. − There are few reports on the study of cationic gemini surfactants. Therefore, a nonionic group (polyoxyethylene ether) and a quaternary ammonium salt molecule structure were combined to synthesize a novel surfactant in this paper, which can simultaneously have the advantages of both cationic and nonionic surfactants.…”

A novel cationic gemini surfactant was prepared by chlorination and quaternization in this paper. The target product was successfully synthesized, which was confirmed by infrared (IR) spectrometer and NMR analysis. Different methods including zeta potential determination, scanning electron microscope, IR, sessile drop method and spontaneous imbibition were used to investigate the mechanism of the wettability alteration of the oil-wet surface by the synthesized gemini surfactant (GABEO) in this work. Results show that the gemini surfactant has excellent surface activity (32.5 mN/m). Ion pair formation is responsible for the mechanisms of wettability alteration of the oil-wet sandstone surface by GABEO, dodecyltrimethylammonium bromide (DTAB), and didodecyltrimethylammonium bromide (GDTAB). Owing to better wettability alteration ability of the synthesized gemini surfactant, there are fewer asphaltene particles on the solid surface treated with GABEO. Compared with DTAB and the traditional gemini surfactant GDTAB, a lower balanced contact angle was obtained for GABEO due to the stronger ion pair desorption capacity; that is, GABEO has a stronger ability to change the wettability of the oil-wet sandstone surface. In addition, owing to the strongest ability to change the surface wettability, the core has the largest ultimate imbibition recovery among the three systems when GABEO is used.
