H 2 SO 4, H 2 O. 1 o alcohol → Carboxylic acid. 2 o alcohol → Ketone. 3 o alcohol → No reaction. Primary alcohols can be oxidized to either aldehydes or carboxylic acids depending on the reaction conditions. In the case of the formation of carboxylic acids, the alcohol is first oxidized to an aldehyde which is then oxidized further to the acid.

2011年11月21日 · The Jones reagent is a mixture of chromic anhydride and dilute sulfuric acid (CrO3 + H2SO4 + H2O) in acetone. It is used in the oxidation of secondary alcohols, that do not contain acid sensitive groups, to corresponding ketones and also the oxidation of primary allylic and benzylic alcohols gives aldehydes.
Jones Oxidation - Organic Chemistry Portal
Disproportionations and single electron transfers lead to chromium (V) acid and stable Cr (III) hydroxide. The chromium (V) acid promotes a two-electron oxidation of an alcohol and becomes Cr (III). Any residues of toxic Cr (V) and Cr (VI) compounds can be destroyed by the addition of an excess of 2-propanol once the intended reaction is complete.

* The Jones reagent is a mixture of chromic anhydride and dilute sulfuric acid (CrO 3 + H 2 SO 4 + H 2 O) in acetone. It is used in the oxidation of secondary alcohols, that do not contain acid sensitive groups, to corresponding ketones. * The primary alcohols are initially oxidized to aldehydes, which are finally oxidized to carboxylic acids.

Oxidation by Chromic Acid - Chemistry LibreTexts
2023年1月23日 · Chromic acid, H 2 CrO 4, is a strong acid and a reagent for oxidizing alcohols to ketones and carboxylic acids. For fairly mundane reasons owing primarily to safety and convenience, chromic acid tends to be made in the reaction vessel as needed (through addition of acid to a source of chromium), rather than being dispensed from a bottle.

NO absorption in a CrO3/H2SO4/H2O solution: experimental and ...
1997年5月19日 · The absorption rates of NO in a CrO 3 /H 2 SO 4 /H 2 O solution have been investigated. A gas/liquid stirring cell and a pilot packing column were used. The experiments, which covered a wide range of gas and liquid concentration, are discussed using the film theory of gas absorption accompanied by a fast chemical reaction.
