Inclusion compounds (intercalates) of fluorinated graphite matrix with 1,2-dichloroethane (C2FxBrz·yC2H4Cl2, x=0.49, 0.69, 0.87, 0.92, z≈0.01) were synthesized by guest substitution from acetonitrile to dichloroethane. The kinetics of the thermal decomposition (the 1st stage of filling→the 2nd stage of filling) was studied under isothermal conditions at 289–313 K. The relationship between the structure of host matrices with thermal properties and kinetic parameters of inclusion compounds is discussed.
