以漆脂、环氧氯丙烷、二乙醇铵、1,4-二溴丁烷为原料,合成了一种漆脂基季铵盐双子表面活性剂。采用红外光谱、核磁共振碳氢谱对其结构进行分析,并对产物的表面性能进行分析。结果表明：合成产物临界胶束浓度(CMC)为5×10-4 mol/L,表面张力(δ)可达33.6 mN/m；当质量分数为0.1%时,分出5 mL水的时间为10 min；表面张力和乳化性能与传统的十六烷基三甲基溴化铵( CTAB)相当。

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 con-firmed by IR,1 HNMR and 13 CNMR,and the surface properties of the surfactant were investigated. The re-sults showed that the critical micelle concentration ( CMC) of the surfactant was 5í10 -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) .
