Description
Summary:Crystallographic characteristics of congruent melting 18-crown-6 crystalline hydrates were specified using X-ray structure analysis. Melting enthalpies of 18-crown-6 tetra- and hexahydrates have been determined; melting points of these compounds have been specified. Liquidus of 18-crown-6–water system has been calculated in the concentration range x H 2 O = 0.750 – 0.935 by using the received data and known thermodynamic properties of the solution.
