摘要: The apparent molar volumes and adiabatic compressibilities of 18-Crown-6, 15-Crown-5, 12-Crown-4, tetraglyme, triglyme were measured at 25°C in H2O D2O. contribution the -CH2CH2O- group to limiting partial cyclic open-chain ethers both solvents are compared solvent isotope effects calculated. It is concluded, based on compressibility results, that there a subtle difference between hydration ethene oxde this persists These results indicate calculation using additivity schemes will have account for whether or compound.
