Catalytic effects of metal chelate compounds.
This paper is essentially a progress report on the developments in the field of metal chelate catalysis since the first review of this subject fifteen years ago'. For the purpose of defining the scope of this field, metal chelate catalysis is considered to include any reaction that is altered or modified by metal ions through chelate ring formation, as well as reactions of metal chelates themse...
متن کاملStudies on uric acid and related compounds. III. Observations on the specificity of mammalian xanthine oxidases.
Xanthine oxidase (X0) has been thoroughly studied by many investigators and the range of possible substrates of this enzyme is well known (1, 2). In the early experiments, enzymatic activity was measured by decolorization of a suitable dyestuff such as methylene blue or by oxygen consumption. Therefore, the exact pathway of oxidation remained unknown for many substrates. The spectrophotometric ...
متن کاملChelate formation of riboflavine with Yttrium (III), Lanthanum (III), and Cerium (III).
Trace elements appears to play an important part in cancer and trace element requirement is a consequence of this disease. Rechenberger 1 has de monstrated experimentally that the iron and cop per content of the blood serum are always disturbed and he showed that cancer elevates the copper level of the serum in all cases, and depresses the iron content to a level well below average, except in...
متن کاملThe Application of Chelate Compounds in Analytical Chemistry
The application of chelate reactions in a general way began a few years before the turn of the century, but the term 'chelate' was coined considerably later by Morgan and his colleagues at the University of Birmingham, who made the first systematic studies. Work in this field has continued at Birmingham for over half a century, apart from a break during the war years. During the last twenty-fiv...
متن کاملCooperative intramolecular interaction of diazacrown ether bearing beta-diketone fragments on an ionic liquid extraction system.
A novel extractant beta-diketone-substituted diaza-18-crown-6 demonstrated very efficient extraction of Sr(2+) due to an intramolecular synergistic effect on the ionic liquid extraction system and recovery of Sr(2+) from the ionic liquid was successfully achieved under acidic conditions.
