Boiling point estimation of 1-butanol and nitromethane by the viscosity- temperature dependence study of corresponding binary fluid systems

Abstract

Calculation of excess quantities in 1-butanol + nitromethane binary mixture (from 303.15 to 323.15) K from experimental shear viscosity and density values were depicted in the previous work. Investigations of these experimental values to test correlation quality of various equations and their corresponding relative functions were also reported. Taking the quasi-equality between the enthalpy of activation of viscous flow ΔH* and the molar activation energy Ea into account, we can define partial activation energy Ea1 and Ea2 for 1-butanol with nitromethane respectively together with their individual contribution separately. Correlation between Arrhenius parameters brings fourth interesting Arrhenius absolute temperature in comparison with the absolute temperature of vaporization in the fluid vapor equilibrium, and the limited corresponding partial molar quantities that can allow us to anticipate the value of the boiling points of the pure constituents. New empirical equations to indicate the boiling absolute temperature are suggested.
