H. Kirss et al., EXCESS-ENTHALPIES OF 3-METHYLPHENOL-N-HEPTANE, 3-METHYLPHENOL-PHENOL-N-HEPTANE AND 3-METHYLPHENOL-1-HEXANOL-N-HEPTANE AT 318.15 K, Chemical engineering communications, 162, 1997, pp. 15-22
Excess molar enthalpies HE for two ternary systems, 3-methylphenol-phe
nol-n-heptane and 3-methylphenol-l-hexanol-n-heptane and a constituent
binary 3-methylphenol-n-heptane have been measured with Calvet-type m
icrocalorimeter at 318.15 K. For predicting ternary excess enthalpies,
the modified Redlich-Kister equation was used. It has been shown that
the second ternary system exhibits regions of both exothermic and end
othermic mixing, and due to the intricated interaction between phenols
and alcohols predicting of ternary excess enthalpies with the Redlich
-Kister equation is unsuccessful.
