Synthesis and Characterization of Rare Earth Chelates (La3+, Pr3+, Nd3+, Eu3+and Tb2+) with Salicylate (4-aminosalicylic acid, 2- acetoxybenzoic acid)

The present study deals with synthesis and characterization of chelates of Salicylates like ( 4-amino salicylic acid, 2-acetoxybenzoic acid) with rare earth metals like La3+, Pr3+, Nd3+, Eu3+and Tb2+. All the compounds were synthesized in different ratios 1: 1, 1: 2 and 1: 3 under different conditions and further characterized by FTIR and XRD pattern. Thermal stability of the prepared compounds was checked by TGA/DTA and DSC method.
