Experimental and Theoretical Research on Mixtures of 2-Methyl-2-butanol and 1-Alkanol (1-Hexanol to 1-Nonanol)

Liquid densities and dynamic viscosities of 2-methyl-2-butanol + 1-alkanol (hexanol to nonanol) were measured at temperatures in the range of 293.15 K to 323.15 K and at pressure of 1 bar. PC-SAFT EoS was used to model the liquid density for pure fluids and binary mixtures composed of 1-alkanol. The advantage of using PC-SAFT EoS is the ability to consider hydrogen bonds between 1-alkanol molecules and between 1-alkanol molecules and 2-methyl-2-butanol molecules. On the other hand, Kendall–Munroe correlation (KMC) and the Nguyenhuynh et al. correlation (NC) were successfully applied to represent the experimental data of dynamic viscosity. Finally, the Redlich–Kister equation correctly correlated the properties of excess molar volume and deviation in dynamic viscosity.
