Chromium trioxide is reported to be better than selenium dioxide 〈62JOC4337〉 and potassium permanganate in acetone is also recommended 〈59JCS3598〉. When the 1-position is fully substituted, oxidation takes place at C-4 using a variety of oxidants 〈69BSF915〉 . hexavalent chromium plating baths. The advantages of the trivalent chromium processes over the hexavalent chromium process are (1) fewer environmental concerns, (2) higher productivity and (3) lower operating costs. The trivalent bath does not contain any appreciable amount of hexavalent chromium, which is more toxic than trivalent chromium. European Parliament decides upon motion to reject chromium trioxide authorisation.

This substance is mainly used in the production of wood preservatives and organic chemicals, but is also used in metal finishing and chrome plating and as a corrosion inhibitor.

Then add more base to precipitate out the chromium as its hydroxide. Chromium Trioxide is a dark red to brown colored, crystalline, inorganic compound that emits toxic chromium fumes upon heating. Chromium trioxide is highly corrosive and is a strong oxidizing agent. It’s not hard to make. You take chromium trioxide, a vicious oxidant in itself which comes as clumpy fine purple crystals, and dissolve it in 6N hydrochloric acid.
