Mechanically activated solid-phase reactions between zinc chloride and sodium beta-diketonates are studied. The course of the reaction, the product yield, and some properties of the activated mixtures are studied in relation to mechanical treatment conditions and the nature of beta-diketone. Zinc beta-diketonates are separated by sublimation from the activated mixtures in >70% yield. Unsolvated zinc beta-diketonates are characterized by physicochemical methods.
