PARTIAL MOLAR VOLUMES OF CRYPTAND-222 IN ORGANIC-SOLVENTS AT 25-DEGREES-C

The partial molar volumes at infinite dilution of cryptand-222 (C-222) in water, methanol, acetonitrile, ethanol, dimethylsulfoxide, propanol, 2 propanol, chloroform, benzene, 1-butanol, cyclohexane, butyl-methylketone, hexane, tetrahydronaphthalene, heptane, octane, cyclohexyl-benzene and decane were measured at concentrations ranging from 0.01 to 0.1 mol-L-1 at 25-degrees-C. The partial molar volumes at infinite dilution showed remarkable dependency on the molar volume of the solvent. The partial molar volumes at infinite dilution for C-222 increase as the solvent molar volume increases.
