General description
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.
Application
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.

Toxicity of the environmental carcinogen chromate is known to involve sulfur starvation and also error-prone mRNA translation. Here we reconcile those facts using the yeast model. We demonstrate that: (i) cysteine and methionine starvation mimic Cr-induced translation errors, (ii) genetic

Chromium enters into the aquatic environment as a result of effluent discharge from steel works, electroplating, leather tanning industries and chemical industries. As the Cr(VI) is very harmful to living organisms, it should be quickly removed from the environment when
