Abstract:
      Lacquer wax-based quarternary ammonium gemini surfactant was synthesized by lacquer wax，epichlorohydrin，diethanol amine and 1，4 - dibromobutane. The structure of the surfactant was confirmed by IR，1HNMR and 13CNMR，and the surface properties of the surfactant were investigated. The results showed that the critical micelle concentration (CMC) of the surfactant was 5×10-4 mol/L and the surface tension(δ) reached 33.6 mN/m. When the mass fraction of the surfactant was 0.1%，5 mL of water was separated in 10 min. The surface tension and emulsification properties of the surfactant were comparable to the traditional cetyl trimethyl ammonium bromide(CTAB).
