Abstract
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.
