Studies on the Oxinates of Antimony

Chemical Analysis of Antimony by Means of Oxine

Abstract

Complex salts of Sb (III) and Sb (V) formed by reaction with oxine have been investigated and the following information obtained : ( 1 ) a complex salt of Sb (III), prepared by treating a solution of antimony chloride successively with tartaric acid and with oxine to precipitate what had heretofore been believed to have the formula SbO C₉H₇NO (C₉H₆NO)₂, was confirmed to be Sb (C₉H₆NO)₃, the same as that prepared without the addition of tartaric acid; ( 2 ) complex salts of Sb( V ) with oxine, dichlorooxine, and dibromooxine were prepared, and it was found that these compounds are useful for the separation of Sb (V) from the other ions and for its quantitative determination.
