Title
Fatty acid methyl esters preparation in the presence of maltolate and n-butoxide Ti(IV) and Zr(IV) complexes
Abstract

Two series of complexes with general formula M(n-butoxide)4−x(maltolate)x, where M = Ti or Zr and x = 0–4, were studied as catalyst for transesterification and esterification, in order to obtain methyl esters. The compounds containing different ratios of maltolate and n-butoxide ligands were synthesized from the reaction of maltol (3-hydroxy-2-methyl-4-pyrone) and n-butoxide metal precursors. All complexes, containing maltolate as ligand, were very efficient as catalyst in esterification, mainly those based in zirconium. In counter part, the catalysts here displayed very poor activity for transesterification.
