摘要: 分别测定了亚硫酸氢钠甲萘醌(MSB)+水+(45%C2H5OH,60%C2H5OH和75%C2H5OH)三元体系在303.15~333.15 K内7个温度下的密度与黏度.对密度、黏度与溶液组成和温度间的关系通过Vogel-Tamman-Fulcher(VTF)方程进行关联,方程的计算值与实验值比较,其标准偏差<1.0%,计算所得表观摩尔体积、极限偏摩尔体积等体积性质数据具有重要的工程应用价值.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.
