Synthesis and thermal studies of Cu(II), Ag(I) AND Pb(II) salts of 2,4,6-trinitroanilinoacetic acid

Abstract

Copper(II), silver(I) and lead(II) salts of glycine- N-(2,4,6-trinitrophenyl) have been prepared in aqueous medium. The thermal behaviour of these salts in air and nitrogen atmospheres has been studied by thermogravimetry and differential thermal analysis. The environment has no effect on the mode of decomposition. Copper and lead salts obtained in the hydrated form, lose water followed by the organic moiety to give their respective metal oxides. Silver metal is the final residue observed during the decomposition of the silver salt. The thermal stability of the salts is in the order: copper salt > silver salt > lead salt.
