ABSTRACT

Densities and viscosities for formic acid and acetic acid with dimethylformamide (DMF) were determined at atmospheric pressure from (303.15 to 353.15) K. The measurements were carried out over the whole range of compositions, using a vibrating-tube density meter and an Ubbelohde viscometer. The density and viscosity measurements were used to compute the excess molar volumes, VE, and viscosity deviations, Ac. The excess molar volumes and viscosity deviations have been fit to the Redlich-Kister equation.
