Abstract
For seven binary systems containing isomeric alkynes, the isobaric var iations of the boiling temperature with liquid-phase composition were determined using a semi-micro ebulliometer over the entire composition range. The experimental data were used to fit the adjustable paramete rs in the Redlich-Kister and Wilson equations. The new UNIFAC interact ion parameters were determined separately for the terminal and interna l triple-bond groups.
