Observation of the dynamic and collective behavior of surfactant molecules at a water/nitrobenzene interface by a time-resolved quasi-elastic laser-scattering method
Article Abstract:
A study was conducted to analyze the dynamic and collective properties of anionic surfactant sodium dodecyl sulfate and neutral surfactant. A spectroscopic method of time-resolved quasi-elastic laser-scattering measurement was utilized to carry out the analysis. Experimental results indicated that the dynamic and collective properties of the surfactant molecules at the interface differed from that of the cationic surfactant cetyltrimethylammonium bromide.

Observation of one process in a phase transfer catalytic reaction at a liquid/liquid interface by using the quasi-elastic laser scattering method
Article Abstract:
A study was conducted to analyze the interfacial characteristics of a phase transfer catalyst called tetrabutylammonium bromide. The quasi-elastic laser scattering technique was utilized to carry out the analysis. A beam from a YAG laser passed through a transmitting diffracting grating in front of a cell. Results indicated that the reaction place between the catalyst and C6H5ONa changed with catalyst concentrations.

Observation of dynamic molecular behavior in a phase transfer catalytic reaction at a liquid/liquid interface by using the time-resolved quasi-elastic laser scattering method
Article Abstract:
Research into the dynamic behaviour of the phase transfer catalyst, quaternary ammonium bromide R4N+Br- (R: n-C4H9, N-C3H7,C2H5), at a water/nitrobenzene interface is presented. The results reflected an interfacial specificity for a chemical reaction and mass transfer.
