RESUMO

The reaction between a suspension of lead dioxide and polyaminocarboxylic adds in neutral medium at 80 degrees has been examined titrimetrically and found to involve decarboxylation in which 3 moles of PbO(2) oxidize 1 mole of the acid, the products being 3 moles of CO(2), 3 moles of HCHO, 1 mole of ethylenediaminemonoacetic acid and 3 moles of Pb(II) followed by chelation of the 3 moles of Pb(II) by an additional 3 moles of EDTA.
