THERMODYNAMIC PROPERTIES OF (A METHYL-ESTER PLUS AN N-ALKANE) .7. H-M(E)-AB-D-V-M(E) FOR (XCH(3)(CH2)(2U-1)CO2CH3 PLUS (1-X)CH3(CH2)(2V)CH3) FOR U=4 TO 7 AND V=2 TO 7

The excess molar enthalpies and volumes H-m(E) and V-m(E) of {xCH(3)(C H2)(2u+1)CO2CH3 (u = 4 to 7) + (1 - x)CH3(CH2)(2v)CH3 (v = 2 to 7)} at the temperature 298.15 K and at atmospheric pressure are reported. Th e excess molar enthalpies of all the mixtures were positive over the e ntire composition range decreasing with the length of the ester and in creasing quasi-linearly with the length of the hydrocarbon. Since the evolution of the excess molar volumes is analogous, this presents nega tive values. A comparative analysis of the theoretical results using s everal models to estimate X(m)(E) and V-m(E) is also included.
