摘要: Densities and viscosities of the binary mixtures N,N-dimethylformamide + N-methyl-2-pyrrolidinone dimethyl sulfoxide have been measured at different temperatures atmospheric pressure, over entire composition range. From these data, excess molar volumes (VE) were calculated for each systems. The densities pure components compared with those reported by other authors available in literature. ρ η fitted to a Redlich−Kister equation, coefficients equation estimate standard deviation are also presented.
