Synthesis, characterization and thermal studies of solid state 4-methylbenzylidenepyruvate of some trivalent metal ions
Main Article Content
Abstract
have been synthesized. Complexometry, X-ray powder diffractometry, infrared spectroscopy and
simultaneous thermogravimetry-differential thermal analysis (TG-DTA) have been used to characterize
and to study the thermal behavior of these compounds. The results provided information concerning the
stoichiometry, crystallinity, thermal stability and thermal decomposition of these compounds.
