Synthesis of chromium(III) chloride

Preparation of chromium(III) chloride

Preparation of chromium(III) chloride

Preparation of chromium(III) chloride

15 g of green chromic oxide are placed in the center of a combustion tube and the latter is placed in a tube oven with temperature control. The exit end of the tube should have, an opening of at least 10 mm to allow for escape of sublimed hexachloroethane, which is formed as a byproduct. 50 milliliters of carbon tetrachloride are placed in a distilling flask fitted with an inlet for carbon dioxide. The side arm of the flask is attached to the combustion tube. A slow stream of carbon dioxide is passed through the carbon tetrachloride warmed to 50° C in a water bath, and the oven is heated to 450° C. At the end of about two hours, when all the carbon tetrachloride has disappeared, the tube is cooled in the inert atmosphere and the violet scales of product are collected. Yield almost quantitative.

Preparation of chromium(III) chloride

10g of pea-size lumps of chromium are placed in the center of a combustion tube and the latter is placed in a tube oven with temperature control.  The combustion tube is connected with chlorine gas from a generator or cylinder. The tube must be both heated and cooled in an atmosphere of chlorine at the beginning and end of the experiment. The temperature of the oven is 450° C, the time of heating is about two hours.

Preparation of chromium(III) chloride

Preparation of chromium(III) chloride

20 g of powdered green chromic chloride are placed in a small round-bottomed flask and 50 ml of freshly distilled thionyl chloride are added. When evolution of gas has ceased, the mixture is refluxed for two hours, the excess liquid evaporated off in vacuo, and the product stored in a vacuum desiccator over pellets of solid alkali for at least 12 hours. Yield almost quantitative.
