| 英文摘要 | Dodecyl polyoxyethylene( 4) polyoxypropylene( 5) ether (LS45) is an outstanding microemulsifier in supercritical CO2. The dynamic surface tension (DST) of this nonionic surfactant was investigated by using the maximum bubble pressure instrument. The effects of concentration and temperature on DST parameters (n, t(i), t*, t(m), and R-1/2) and its adsorption mechanism were discussed by Rosen's empirical equation and the asymptotic Ward and Tordai equation for the LS45 solution system. Finally, the parameters at 1 s related to Draves's wetting performance, pC(20(1s)), C-1s (i)*, and C-1s*, analyzed. The results showed that were with increase of bulk concentration and temperature, dynamic surface activity increased. Parameters at 1 s indicated that LS45 is of high surface activity and a very good wetting agent. One-second related parameters, C-1s (i)* and C-1s*, are valuable in the treatment of practical applications of surfactants. Optimum wetting can be expected at the concentration of 4.8 x 10(-4) mol/dm(3) for LS45 solution. |
