EXCESS-ENTHALPIES OF (METHYL 1,1-DIMETHYLPROPYL ETHER PLUS 2,3-DIMETHYLBUTANE OR CYCLOHEXANE PLUS DECANE) AT THE TEMPERATURE 298.15 K

Microcalorimetric measurements of excess enthalpies at the temperature 298.15 K are reported for the two ternary mixtures (methyl 1,1-dimeth ylpropyl ether + 2,3-dimethylbutane + decane) and (methyl 1,1-dimethyl propyl ether + cyclohexane + decane). Smooth representations of the re sults are presented and used to construct constant-enthalpy contours o n Roozeboom diagrams. Comparisons of the experimental results with est imates based on the Flory theory of mixtures are also described.
