Sažetak

Two methods for the laboratory preparation of anhydrous chromium(III) chloride are described in the standard handbooks of inorganic syntheses, i. e. (i) the chromium metal is heated in a porcelain tube in a stream of chlorine at high temperature, (ii) the green aqua-chloride [CrCl2 (H2 0)4 ]Cl · 2H20 is heated and the resulting mass of oxide and basic chloride is then chlorinated with carbon tetrachloride.
