Thermal dissociation processes for clathrates [CuPy4(No3)2]·2g (G=tetrahydrofurane, chloroform)
摘要:
The thermal dissociation processes of clathrates [CuPy4(NO3)(2)].2G (G=tetrahydrofuran, chloroform) were studied. Thermodynamic parameters (DeltaH(av)(0), DeltaS(298)(0) and DeltaG(298)(0)) of the processes, producing solid host complex [CuPy4(NO3)(2)] and gaseous guest (G), were determined from the strain measurements. These data are compared with previous data for clathrates of the host complex with benzene and pyridine. Quasi-equilibrium thermogravimetry was used to investigate the step-by-step character of the dissociation processes. Kinetic studies were carried out for clathrate [CuPy4(NO3)(2)].2THF.
