Abstract
Optimum conditions for the preparation of sodium hexachlororhodate(III) were determined by chlorinating mixtures of sodium chloride and rhodium. By employing a high temperature (900°C), 100% excess sodium chloride, and mechanical agitation of the reaction mixture, almost quantitative conversion can be obtained with a single 30 min chlorination. Although the product may be recovered in low yield as large red crystals of the 12-hydrate by evaporating an aqueous solution of the reaction mixture at room temperature, recovery in ca. 85% yield by precipitation with acetone and vacuum desiccation to the 2-hydrate is recommended.
