THE CHEMICO-ANALYTIC CHARACTERISTICS OF THE REAGENTS OF THE BISMUTHOLS AND ITS COMPLEXES WITH BISMUTH (III) AND COPPER (II)

It has been establiched, that in the aproton solvents the reagents are in the thion-thiol form. The dependence between the reagents paint and its state has been established. The connection of the metal ion with the ligand is being realized through the thiol atom of sulphur and through the thion atom of sulphur in coordinated way. The new data about the conditions of isolation of the acid forms, the state of the reagents, which cane be used for a synthesis and study of the new reagents, have been obtained. The methods of the extraction-photometric determination of bismuth in brasses have been developed and introduced in serviceAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
