Abstract
The densities and viscosities for ternary mixtures of menadione sodium bisulfite + water +(45%C2H5OH,60%C2H5OH and 75%C2H5OH,respectively) have been determined experimentally at 303.15~333.15 K.The dependence of density and viscosity on temperature and concentration has been correlated by means of the Vogel-Tamma-Fulcher(VTF) equation.The standard deviation between equation calculated and experimental values was less than 1.0%.The apparent molar volumes and limiting partial molar volume from the experiment measurements were calculated.The results have a great significance in application.
