Determination And Algebraic Representation Of Volumes Of Mixing At 298.15-K Of Methyl N-Alkanoates (From Ethanoate To N-Pentadecanoate) With N-Pentadecane

Abstract

The present paper sets out the excess volumes, upsilon(E), for binary mixtures composed of one of fourteen methyl esters, from ethanoate to n-pentadecanoate, and n-pentadecane calculated indirectly from density value measurements carried out at 298.15 K and normal atmospheric pressure. All the mixtures presented upsilon(E) > 0 which decreased in a quasi-regular manner as the chain length of the methyl ester increased. The correlation of the experimental upsilon(E) values with concentration was calculated using an appropriate polynomial equation which yielded excellent results. Development of the equation is also discussed.
