This study is devoted to the investigation of physical and chemical properties of MoO2(C6H5CONHO)2 complex and its crystallosolvates. The quantitativ estimation of the energy of solvent molecules tearing off complex molecule depending on structure of crystallosolvate and solvent nature is given. Dominant mechanism of crystallosolvates thermodissociation kinetics in a=0,5-50% range of conversion amount has been determined. lg A=aE+b compensation effect relationship is established to be specific to the isostructural or similarly constructed coordinativ compounds.
In 270-320K temperature range with constant pressure in adiabatic regime the heat capacity of MoO2(C6H5CONHO)2 complex and its crystallosolvates have been measured. The polynominals of the heat capacity equations have been calculated for the substances under study. The crystallosolvates thermodinamic parameters calculated have been compared with the kinetic ones of their topochemical dissociation and correlated with their packing types. On adsorption parameters of polar solvent (n-buthanol and aceton) from unpolar medium (benzene) the comparative adsorptiv characteristics of the MoO2(C6H5CONHO)2 and WO2(C6H5CONHO)2 complexes are given. These substances are recommend as synthetic sorbents for unpolar solvents cleaning from minute quantities of polar ones.
