A new series of carbosilane quaternary ammonium surfactants with different hydrophobic carbosilane structures (triethylsilyl, triisopropylsilyl, trihexylsilyl, triphenylsilyl) and tail groups (C12, C16, C18) have been synthesized and the structures of the organosilicon carbosilane quaternary ammonium surfactants were determined by means of FTIR, NMR and elemental analysis. The properties of aqueous solutions were determined by electrical conductivity measurements and with the method of maximum bubble formation. Members of this series reduced the surface tension of water to approximately 30.5 mN/m at concentration levels of 0.14 mmol/L.

碳硅烷季铵表面活性剂的制备及表面活性

具有不同疏水碳硅烷结构(三乙基甲硅烷基、三异丙基甲硅烷基、三己基甲硅烷基、三苯基甲硅烷基)和尾基(C12, C16, C18)合成了有机硅碳硅烷季铵盐表面活性剂的结构,通过FTIR、NMR和元素分析确定了有机硅碳硅烷季铵表面活性剂的结构。水溶液的性质通过电导率测量和最大气泡形成方法确定。该系列的成员在 0.14 mmol/L 的浓度水平下将水的表面张力降低到大约 30.5 mN/m。
