Volumetric properties of cyclic hydrocarbons in tetrachloromethane at 25{degrees}C
By means of a vibrating-tube densimeter, the densities at 25{degrees}C have been determined for binary mixtures of tetrachloromethane with a liquid (cyclodecane, cis-decahydronaphthalene, trans-decahydronaphthalene, bicyclohexyl, pentane) or a solid hydrocarbon (cyclododecane, cyclopentadecane, norbornane, adamantane, octahydro-4,7-methano-1H-indene). Excess molar volumes have been obtained in the whole mole fraction range for mixtures containing a liquid hydrocarbon. For solid cycloalkanes, apparent molar volumes have been evaluated in the whole range of miscibility. The partial molar volumes at infinite dilution {bar V} have been calculated for all examined cycloalkanes and compared with those of n-alkanes. The dependence of {bar V} upon the size and shape of the ring or cage structure of the solute is discussed. The capability of the Flory theory to reproduce V{sup E} for these mixtures is also tested.
