High water solubility cationic gemini surfactant, and preparation method thereof
2015
The invention discloses a high water solubility cationic gemini surfactant, and a preparation method thereof. The chemical formula of the high water solubility cationic gemini surfactant is N,N,N',N'-tetra-hydroxyethyl-N,N'-dialkyl-2-hydroxyl propane diamine. The high water solubility cationic gemini surfactant is capable of realizing mutual dissolution with water, possesses relatively high surface activity and relatively low critical micelle concentration (CMC), CMC is 7.4*10 mol/L, gamma(CMC) is 29mN/m , the high water solubility cationic gemini surfactant is capable of reducing surface resistance of fabric effectively, and possesses excellent antistatic properties. Raw materials needed by the preparation method are cheap and easily available; reaction conditions are mild; reaction is safe; and the preparation method is suitable for industrialized production.
