Infinite-Dilution Activity-Coefficients by Comparative Ebulliometry - Measurements and Group-Contribution Calculations for Some Binary-Mixtures Ether Plus N-Alkane and Ether Plus Alcohol

Delcros S, Grolier JP, Dohnal V, Fenclova D

Infinite-dilution activity coefficients gamma(i)(infinity) were measured for 33 solute-solvent pairs of the type ether + n-alkane and ether + alcohol using the comparative ebulliometry technique. The experimental results were compared with the values obtained by two group contribution models, DISQUAC and modified UNIFAC (Dortmund).
