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

✦ Synopsis
Flow-microcalorimetric measurements of excess molar enthalpies H E m at the temperatures 298.15 K and 308.15 K are reported for 4x(CH3)3CCH2CH(CH3)2, or CH3(CH2)4CH.CH2, or CH3(CH2)3CH.CH2, or C6H5CH3 + (1 -x)CH3OC(CH3)35 and 4xCH3(CH2)4CH.CH2, or CH3(CH2)3CH.CH2, or C6H5CH3 + (1 -x)CH3OC(CH3)2C2H55. The results are discussed in terms of the NRTL, UNIQUAC and Prigogine-Flory-Patterson (PFP) models.
