The microemulsion of the H/sub 2/O/Tween 80/benzene derivative (C/sub 6/H/sub 6/, CH/sub 3/C/sub 6/H/sub 5/, NO/sub 2/C/sub 6/H/sub 5/ and NH/sub 2/C/sub 6/H/sub 5/) was investigated by the technique of Photon correlation spectroscopy. Autocorrelation data were measured at 90 scattering angle and were analyzed by using a quadratic fit and linear fit. The quadratic fit was found to describe all properties better than the linear fit, and thus the linear fit was limited to the region of very short sampling time. When the amount of benzene derivative added to the sample solution was lower than V/sub max/, the Z-average mean radius,
/sub z/, and the polydispersit Y,(.mu./sub 2/).div.(.GAMMAbar./sup 2/), increased as the amount of benzene derivative was increased. When the amount of benzene derivative was larger than V/sub max/, the aqueous and organic phases separated and the /sub z/, and(.mu./sub 2/).div.(.GAMMAbar./sup 2/) of all phases remained constant. Emulsification did not occur in the organic phase of the H/sub 2/O/Tween 80/aniline system. When we adjusted the Tween 80 concentration, it was found that /sub z/ and(.mu./sub 2/).div.(.GAMMAbar./sup 2/) decreased as the Tween 80 concentration increased. - 英文摘要: --
