Excess volumes and relative permittivity increments of {xH(2)C=CHCO2CH3+(1-x)CnH2n+2 (n = 5, 6, 7, 10, and 12)}
The excess molar volumes V-m(E), increments in the relative permittivity delta epsilon(r), and molar electrical susceptibility delta chi(c) of {xH(2)C=CHCO2CH3 + (1 - x)CnH2n+2} have been determined from the experimentally measured densities and relative permittivities at the temperatures 298.15K and 308.15 K. The V-m(E) values are positive in all the mixtures and increase quasi-regularly as the alkane chain length increases. The delta epsilon(r) and delta chi(e) values were, in general, predominantly negative with few positive points at the ester-rich regions in tester + n-pentane) at T = 298.15 K, and tester + n-alkanes) at T = 308.15 K.
