“…In order to define better the thermophysical properties of 2,5,8,11,14-pentaoxapentadecane or tetraglyme with other components and within the framework of the investigation on the determination of thermophysical properties of binary liquid mixtures containing (glymes + n-alkanes or organic carbonates) [25][26][27][28][29], we report in this paper experimental relative permittivity, e, at frequency 1 MHz, and density on mixing, q, over the whole composition range at T = (288. 15, 298.15, 308.15, 318.15, and 328.15) K for the binary mixtures 2,5,8,11,14-pentaoxapentadecane or {tetraglyme + dimethyl (DMC) or diethyl carbonate (DEC)} at atmospheric pressure.…”
