Get the latest price. 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.
