✦ Synopsis

The results were compared with the values of H E m for the related mixtures, and the possible hydrogen bonding between the alkyne and the ether noted. Various theories of liquid mixtures were fitted with the results. The H E m results were discussed in terms of the NRTL and UNIQUAC models, and were calculated by using the values of V E m (x = 0.5) by the Prigogine-Flory-Patterson (PFP) theory using Flory's equation of state and a free volume contribution.
