PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. Unlike chromic acid, PCC will not oxidize aldehydes to carboxylic acids. Similar to or the same as: \(CrO_3\) and pyridine (the Collins reagent) will also oxidize primary alcohols to aldehydes. Here are two examples ...

Chromium trioxide (CrO3) is a dark red/orange solid that acts as a strong oxidizing agent. In organic chemistry it is most often associated with Jones oxidation. Reagent for the conversion of primary alcohols to carboxylic acids (Jones oxidation) Procedure excerpt:

A solution of chromium trioxide in aqueous sulfuric acid can be safely mixed with acetone (Jones Reagent). If this mixture is slowly added to an alcohol in acetone, oxidation products such as carbonyl compounds and carboxylic acids can be isolated in good yields (Jones Oxidation).

CHROMIUM TRIOXIDE is a powerful oxidizing agent. Can react violently upon contact with reducing reagents, including organic matter, leading to ignition or explosion.

Nov 21, 2011 · The Jones Oxidation allows a relatively inexpensive conversion of secondary alcohols to ketones and of most primary alcohols to carboxylic acids. The Jones reagent is a mixture of chromic anhydride and dilute sulfuric acid (CrO 3 + H 2 SO 4 + H 2 O) in acetone.

Chromium trioxide is mainly used in chrome plating. It is typically employed with additives that affect the plating process but do not react with the trioxide. The trioxide reacts with cadmium, zinc, and other metals to generate passivating chromate films that resist corrosion. It is also used in the production of synthetic rubies.

Mixing CrO 3 with concentrated H 2 SO4, water, and acetone forms aqueous chromic acid (Jones reagen t). Mixing CrO 3 with pyridine and hydrochloric acid forms pyridinium chlorochromate (PCC).

Mar 7, 2025 · CrO3 with H2SO4 is known as the Jones reagent, which is highly effective for the oxidation of primary alcohols to aldehydes and secondary alcohols to ketones. This reagent is commonly used because it provides selective oxidation without …

Feb 23, 2021 · The Jones oxidation uses chromium trioxide (CrO3), acid, water, and acetone to convert 1° or 2° alcohols into carboxylic acids or ketones respectively.
