The Coordination of Rare Earth Elements with Derivatives of Catechol(Ⅴ) The Coordination and Transformation Reaction of Cerium with 3,4-Dihydroxybenzoic Acid

Abstract

Abstract: The complex of cerium(Ⅲ) with 3,4-dihydroxybenzoic acid was prepared in aqueous solution of pH=5.6～9.0, and the formula Ce(H₂L)₂(OH)·3H₂O was determined by means of IR, TG-DTA and elementary analysis. In alkaline aqueous solution, the cerium cation of the complex can be transformed from carboxyl group to dihydroxyl group in the same ligand and formed a new chalation compound.

Key words: Cerium, 3,4-Dihydroxybenzoic acid, Coordination reaction, Transformation reaction, Oxidation
