Abstract  

Inclusion compounds: intercalates of fluorinated graphite matrix with acetonitrile (C2FxBrz yCH3CN, x=0.92, 0.87, 0.69 and 0.49, z≈0.01) were synthesized. The kinetics of the thermal decomposition (the 1st stage of filling→the 2nd stage of filling) was studied under isothermal conditions. The relationship between intercalates properties and composition and structure of the matrix is discussed.

Abstract  

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.

Abstract  

Thermodynamic and kinetic stability of inclusion compounds (so called supermolecular compounds) is discussed. Compounds under study and discussion are clathrates (with coordination compounds matrices) and intercalates (with fluorinated graphite matrices).

Abstract  

Inclusion compounds (intercalates) of fluorinated graphite matrix with chloroform (C2FxBrz·yCHCl3, x=0.49, 0.69, 0.87, 0.92, z=0.01) were synthesized by guest substitution from acetonitrile to chloroform. The kinetics of the thermal decomposition (the 1st stage of filling → the 2nd stage of filling) was studied under isothermal conditions at 286–311 K. The relationship between the structure of matrices intercalates with thermal properties and kinetic parameters of inclusion compounds is discussed.

Abstract  

Inclusion compounds (intercalates) of fluorinated graphite matrix with methylene dichloride (C2F x Br z ·yCH2Cl2, x = 0.49, 0.69, 0.87, 0.92, z ≈ 0.01) were synthesized by guest substitution from acetonitrile to methylene dichloride. The kinetics of the thermal decomposition (the first stage of filling → the second stage of filling) was studied under isothermal conditions at 291–303 K. The relationship between the structure of host matrices with thermal properties and kinetic parameters of inclusion compounds is discussed.

Abstract

Thermal dissociation processes for acetonitrile inclusion compounds based on the polymer fluorographite host matrix C2F x Br0.01·yCH3CN, where x = 0.49–0.92, y = 0.174–0.285, are investigated. Thermodynamic parameters (ΔH°av, ΔS°av, ΔG°298) for deintercalation of the compounds of the first filling step into the compounds of the second step and gaseous guest within temperature range 294–352 K were determined. The effect of the host matrix fluorination degree on the thermodynamic characteristics of the studied processes is demonstrated.

Abstract

Inclusion compounds (intercalates) of fluorinated graphite matrix with acetone (C2F x Br z ·y(CH3)2CO, x = 0.49, 0.69, 0.87, 0.92, z ≈ 0.01) were prepared by guest substitution from acetonitrile to acetone. The kinetics of the thermal decomposition (the first stage of filling → the second stage of filling) was studied under isothermal conditions at 292–313 K. The relationship of the host matrices structure with inclusion compounds thermal properties and kinetic parameters is discussed.
