Dk. Liao et al., EXCESS-ENTHALPIES OF (N-HEPTANE OR N-DECANE) PLUS METHYL TERT-BUTYL ETHER PLUS DI-N-PROPYL ETHER TERNARY MIXTURES AT 298.15 K, Fluid phase equilibria, 131(1-2), 1997, pp. 133-143
Excess molar enthalpies, measured at 298.15 K in a flow microcalorimet
er, are reported for the ternary mixtures (n-heptane + methyl tert-but
yl ether + di-n-propyl ether) and (n-decane + methyl tert-butyl ether
+ di-n-propyl ether). Smooth representations of the results are descri
bed and used to construct constant excess molar enthalpy contours on R
oozeboom diagrams. It is shown that good estimates of the excess entha
lpies of the ternary mixtures can be obtained from the Flory theory, u
sing only the physical properties of the components and their binary m
ixtures. (C) 1997 Elsevier Science B.V.
