Paragraph 0068; 0069; 0080, (2018/03/01)
The invention discloses a glucosyl-gemini nonionic surfactant and a synthesis method thereof. The glucosyl-gemini nonionic surfactant is obtained by performing a reaction on bis(C8-C18 long-chain alkyl glyceryl ether) diamine and glucolactone; the glucosyl-gemini nonionic surfactant combines the advantages of mild and no-irritating texture, high possibility of biodegradation and environmental friendliness of a sugar-based surfactant and also has excellent performances of a gemini surfactant for further improving the surface activity, lowering the critical micelle concentration and the like, and therefore, the glucosyl-gemini nonionic surfactant is a multi-functional surfactant; the glucosyl-gemini nonionic surfactant can be widely applied in the industries of chemicals for daily use, petroleum, pesticides, spinning, paper making, mining and the like, and therefore, the glucosyl-gemini nonionic surfactant has a broad application prospect.

New imidazolium gemini surfactants were synthesized by reaction of epichlorohydrin with long chain fatty alcohols furnishing products 2-(alkoxymethyl)oxirane followed by their subsequent treatment with imidazole resulting in the formation of 1-(1H-imidazol-1-yl-3 alkoxy)propane-2-ol which on subsequent treatment with 1,2-dibromoethane and 1,3-dibromopropane resulted in the formation of title gemini surfactants:1,2-bis(1(3-alkoxy-2-hydroxypropyl)- 1H-imidazol-3-ium)ethane bromide (7), 1,3-bis(1(3-alkoxy-2-hydroxypropyl)-1H- imidazol-3-ium)propane bromide (8), 1,2-bis(1(3-alkoxy-2-hydroxypropyl)-1H- imidazol-3-ium)ethane bromide (9), 1,3-bis(1(3-alkoxy-2-hydroxypropyl)-1H- imidazol-3-ium)propane bromide (10), 1,2-bis (1(3-alkoxy-2-hydroxypropyl)-1H- imidazol-3-ium)ethane bromide (11) and 1,3-bis (1(3-alkoxy-2-hydroxypropyl)-1H- imidazol-3-ium)propane bromide (12). Their identification was based on IR, 1H-, 13C-NMR, DEPT, COSY and mass spectral studies. Their surface active properties were also evaluated on the basis of surface tension and conductivity measurements.
Physicochemical properties of novel phosphobetaine zwitterionic surfactants and mixed systems with an anionic surfactant

experimental part, p. 433 - 438 (2012/07/14)
A series of novel zwitterionic phosphobetaine (PPBT) surfactants were synthesized using long chain fatty alcohol, epichlorohydrin, dimethylamine and sodium dihydrogen phosphate as raw materials. The physicochemical properties of the phosphobetaine surfactants such as isoelectric point, foaming, surface tension, critical micelle concentration (CMC) and Krafft point were measured. Low CMC and surface tension values indicated the surface activities of the phosphobetaine surfactants were quite excellent. The CMC and surface tension values of PPBT/SDS mixed systems were determined. It was found both of CMC and surface tension values decreased compared with single surfactant system because of the association between dodecyl sulfate anions and cationic groups in phosphobetaine by electrostatic attraction.
