The dynamic surface tensions(DST) of tetradecyltrimethylammonium bromide(TTAB) solutions at various concentrations are measured by the drop volume method at 30℃.

Based on the characteristic of negative charges exchange of montmorillonite(MMT),making the dodecyl trimethyl ammonium chloride(BS-12) imbedded in the layer of MMT,we pretreated MMT and enhanced the dispersion of MMT in MMA.

The mixed micellar size, relative arrangement and interaction sites of the nonionic sugar-based surfactant n-dodecyl-β-D-maltoside (DM) and dodecyl trimethyl ammonium chloride were studied using NMR by self-diffusion coefficient, spin-spin and spin-lattice relaxation time, and two-dimensional nuclear Overhauser enhancement (2D NOESY).

Study on the conditions of preparing organic montmorillonite under the synergic effect of tetraethyl ammonium bromide and octadecyltrimethyl ammonium chloride;

The attapulgite was organically modified using octadecyltrimethyl ammonium chloride after ion exchange with saturated sodium chloride.

Study on floatation separation of mercury in ammonium thiocyanate-cetyltrimethylammonium chloride system;

The dissociated tetrachloroaurate(Ⅲ) was produced by the ion-pair complex of tetrachloroaurate(Ⅲ) with timolol maleate when it entered into the reversed micellar water pool formed by the cation surfactant cetyltrimethylammonium chloride(CTAC) in a chloroform-cyclohexane(3∶7 by volume)-water(0.
