ABSTRACT

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