Abstract

Abstract: The densities of binary solution C₆H₆-DMF(benzene-N,N-dimethylformamide) at 293.15 K were measured by use of the Anton Paar vibrating-tube densimeter, the molar fractions of benzene for the binary solution is from 0 to 1. The apparent molar volumes of C₆H₆ and DMF in the binary system C₆H₆-DMF were separately calculated from the density data, and the optimized dependences between apparent molar volumes and molar fractions and mass fractions were also determined, respectively, by the nonlinear least-square Regression, and further more, the standard partial molar volumes and the molar volumes of C6H6 and DMF were also obtained from the functions limits. At the same time, the excess molar volumes for the binary solution were calculated and were fitted by the fourth-order Redlich-Kister equation well, so the Redlich-Kister coefficients and the excess molar volume extremum were obtained.

Key words: Benzene-N,N-dimethylformamide, Density, Apparent molar volume, Excess molar volume
