✦ Synopsis

The excess molar volumes V E , increments in the relative permittivity ␦ , and molar m r

determined from the experimentally measured densities and relative permittivities at the temperatures 298.15 K and 308.15 K. The V E values are positive in all the mixtures and m increase quasi-regularly as the alkane chain length increases. The ␦ and ␦ values were, r e in general, predominantly negative with few positive points at the ester-rich regions in Ž . Ž . ester q n-pentane at T s 298.15 K, and ester q n-alkanes at T s 308.15 K.
