摘要
Experimental data on density of (dimethyl sulfoxide + benzene, or toluene, or ethylbenzene, or styrene) were obtained at temperatures (293.15, 303.15, 313.15, 323.15, 333.15, 343.15, 353.15) K and atmospheric pressure by means of a vibrating-tube densimeter. From these data, excess molar volume has been calculated. The computed quantities have been fitted to the fourth-order Redlich-Kister equation to derive the coefficients and estimate the standard error values. It was found that the V,E in the systems studied increases with rising temperature. (C) 2004 Elsevier Ltd. All rights reserved.
