Measurement and Correlation of Infinite Dilution Activity Coefficients of Alcohols in Hexadecane and Tetradecane

Abstract

The infinite dilution activity coefficients of alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, and 2-butanol) in heavy paraffinic hydrocarbons (hexadecane and tetradecane) were measured in the region 20-80°C by a gas stripping method. The ASOG model was applied to calculate the infinite dilution activity coefficients. The infinite dilution activity coefficients can be correlated by adjusting the group interaction parameters between hydroxy and methyl groups.
