Resumen
The composition of fhe zinc dialkylphosphorodithioate complex which partitions between aqueous acid solutions and C CI 4 has been established as [(RO)2 PSS]2Zn. Characteristic constants have been evaluated; these include the over-all extraction constant, the partition coefficient of the zinc complexes, and the stability constant of the zinc di-n-butyl and diisobutyl esters. The extraction mechanism is discussed briefly and the characteristic constants obtained for zinc are compared with those reported for dialkylphosphate complex of zinc.
