Abstract

A substituted derivative of acetylacetone -- 1,1,1-triflouro-5-methyl-2,4-hexanedione -- has been synthetized and characterized. The authors have determined its pK(a), distribution constant K(D) in water-organic phase systems (p-xylene, benzene, n-hexane), and the values characterizing the extraction of Cu, Cd and Pb with this reagent, pH1/2, pK(ex). The composition of the extracted particles with the metal and the stability constants of chelates, log beta-1 and log beta-2, have also been determined.
