ABSTRACT

3C E h /J mol OC O CH H The molar excess volumes of the three binary mixtures methyl decanoate + n-alkane (n-dodecane, n-tetradecane, n-hexadecane) were measured at temperature = 298.15 K and atmos200 pheric pressure using a vibrating-tube densitometer. Furthermore, the molar x excess enthalpies of the six binary mixtures methyl decanoate + n-alkane (n-hexane, n-octane, n-decane, n-dodecane, n-tetradecane, n-hexadecane) were measured at the same ambient conditions applying a Calvet microcalorimeter. Both excess properties showed an increase with increasing chain length of the n-alkane. Two equations of state, namely a heterosegmental approach of PC-SAFT and SAFT- Mie, were applied in order to predict the excess properties of the respective binary mixtures. Very satisfying agreement between experimental data and modeling results was obtained for both equations of state.
