Abstract: A simple and convenient procedure for the synthesis of magnetite by heating iron(III) hydroxoacetate at temperatures above 250 °C under nitrogen is reported. The reaction product was characterized by X-ray diffraction, surface area determination and chemical analysis. On heating, the amorphous hydroxoacetate loses hydroxyl and acetate groups, as observed in the infrared spectra; evolved ammonia, carbon dioxide, acetone and acetic acid were identified; iron(II) formation in the hydroxoacetate is slow below 250°C but its rate increases with increasing temperature. At 382°C the iron(II) content in the product is 22.5% and the total iron content is 72.1%. © 1987.
