Synthesis and thermal studies of solid state 2-chloro- benzylidenepyruvic acid and its compounds with sodium, aluminium (III), gallium (III) and indium (III) cations

The synthesis of sodium 2-chlorobenzylidenepyruvate and its corresponding acid as well asbinary, binary together with it’s acid or hydroxo-2-chorobenzylidenepyruvate of aluminium (III), gallium(III) and indium (III), were isolated. Chemical analysis, thermogravimetry, derivative thermogravimetry(TG/DTG), simultaneous thermogravimetry-differential thermal analysis (TG-DTA) and X-ray powderdiffractometry have been employed to characterize and to study the thermal behaviour of these compounds.The results provided information concerning the stoichiometry, crystallinity, thermal stability and thermaldecomposition.
