摘要: Enthalpies of solution 15-crown-5 (15C5) in the mixtures water with acetonitrile (AN) or propan-1-ol (PrOH) and benzo-15-crown-5 ether (B15C5) PrOH-water have been measured at 298.15 K. The values standard enthalpies 15C5 are negative AN within whole range mixture composition water-PrOH for content xw>0.1 those B15C5 positive (except enthalpy pure water) system water-PrOH. results calorimetric measurements together earlier data water-acetonitrile discussed regard to intermolecular interactions that occur these systems.
