Volumetric Properties and Viscosities for Aqueous N-Methyl-2-pyrrolidone Solutions from 25 deg C to 70 deg C

摘要

This paper reports the densities and viscosities of aqueous N-methyl-2-pyrrolidone (NMP)solutions at five temperatures in the range 25 deg C to 70 deg C over the whole concentration range.The results are compared with data published in the literature.The derived excess molar volumes,the partial molar volumes,the partial molar volumes at infinite dilution,and the viscosity deviations were correlated as a function of composition.
