一般描述
Chromium (VI) oxide is acidic anhydride of chromic acid. It is a useful oxidizing reagent for the conversions of:,Carbon-hydrogen bonds to alcohols,,Alkenes to α, β-unsaturated ketones,Alcohol to aldehydes, acids, and keto acids.
应用
与氯化铵一起用于将氢化苯偶姻氧化成苯偶酰。
Chromium (VI) oxide may be employed as a catalyst for the following reactions:
- Transformation of various primary alcohols to carboxylic acids.
- Oxidation of arenes (naphthalenes and anthrathene) to the corresponding quinones by using periodic acid as the terminal oxidant in acetonitrile.
- Benzylic oxidation of various substituted toluene to the corresponding benzoic acids.
- Oxidation of sulfides to sulfones.

The effect of chlorophyllin on micronucleated polychromatic erythrocytes (MN-PCE) induction by chromium trioxide (CrO(3)) exposure in peripheral blood of mice was studied. Animals were treated with a single intraperitoneal dose of chlorophyllin (CHL) (20mg/kg), CrO(3) (20mg/kg), and CHL (20mg/kg) 4h
