THE STUDY OF ENTALPHY OF FORMATION FOR DIRHENIUM(III) TRANS-TET RACHLORO-DI-μ-CARBOXYLATE S

Abstract

Exothermic reactions for dirhenium(III) trans-tetrachloro-di-μ-carboxylates (trans- [Re2Cl4(RCOO)2], were R = C2H5; C3H7; (CH3)2CH; (CH3)3C) of burning in air were investigated. The products of burning by methods of chemical analysis were studied. The experimental enthalpy changes of reactions of complexes burning were obtained by the DTA curves. Standard enthalpies of formation for trans-[Re2Cl4(RCOO)2] (where R= C2H5; C3H7; (CH3)2CH; (CH3)3C) are 36966; 63531, 35541, 66350 kJ/mol; they the were obtained by second law of thermochemistry (Hess law). Theoretical enthalpies of formation for trans-carboxylates of dirhenium(III) were calculated by Linus Pauling semiempirical method. The thermodynamic possibilities of reactions with deposition of pure metal rhenium were measured. This investigation can be used in chemical vapor deposition (CVD) of metal rhenium.
