✦ Synopsis

Excess molar volumes of ternary-pseudobinary liquid mixtures {benzene + (N ,Ndimethylformamide or N ,N -dimethylacetamide + CCl 4 )} and the apparent molar volumes of benzene in the binary mixtures of {N ,N -dimethylformamide, or N ,Ndimethylacetamide + CCl 4 } have been obtained by measuring density using an Anton Paar Model DMA 60/602 vibrating-tube densimeter, in the range of dilute concentration. The infinite dilution partial molar volumes of benzene were obtained by extrapolating the mole fraction of benzene to y = 0. The experimental results show that the partial molar volumes at infinite dilution for benzene decrease as the mole fraction x of N ,Ndimethylformamide or N ,N -dimethylacetamide in pseudo-pure component increases.
