Abstract

The synthesis of sodium 2-chlorobenzylidenepyruvate and its corresponding acid as well as
binary, 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 powder
diffractometry 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 thermal
decomposition.
