SECONDARY STANDARDS .2. ACETYLACETONATES

The preparation of several acetylacetonates is described, the novel feature being that the organic reagent is added in substoichiometric amount. Several of the compounds are obtainable 99.9% pure or better, and are proposed as secondary standards for the metals they contain or for elementary analysis. These are the copper(II), chromium (III), zinc, cadmium, magnesium, thorium, cobalt(III), iron(II) and calcium compounds. Cobalt (II) and nickel dipyridine acetylacetonates are also proposed. Aluminium and beryllium acetylacetonates are suitable as routine test materials. © 1968.
