OXIDATION OF ALCOHOLS - chemguide
This page looks at the oxidation of alcohols using acidified sodium or potassium dichromate(VI) solution. This reaction is used to make aldehydes, ketones and carboxylic acids, and as a way of distinguishing between primary, secondary and tertiary alcohols.
Potassium dichromate - Wikipedia
Potassium dichromate is an oxidising agent in organic chemistry, and is milder than potassium permanganate. It is used to oxidize alcohols. It converts primary alcohols into aldehydes and, under more forcing conditions, into carboxylic acids. In contrast, potassium permanganate tends to give carboxylic acids as the sole products.

Oxidation of Alcohols | AQA A Level Chemistry Revision Notes 2015
2024年10月27日 · For potassium dichromate(VI) to act as an oxidising agent, it itself needs to be reduced. This reduction requires hydrogen (H +) ions which are provided by the acidic medium. When alcohols are oxidised the orange dichromate ions (Cr 2 O 7 2-) are reduced to green Cr 3+ ions. Acidified potassium manganate(VII), KMnO 4, is a purple oxidising agent
Potassium dichromate - Sciencemadness Wiki
2022年10月16日 · Potassium dichromate is a powerful oxidizing agent, containing chromium in the +6 oxidation state. It may react violently with reducing agents, such as finely divided metals, making it a viable ingredient in flash powder .
Potassium DiChromate: Structure, Preparation and Properties
Potassium dichromate is used as an oxidizing agent in organic reactions. To function effectively, it needs to be reduced. Acidifying potassium dichromate provides hydrogen ions (protons) from the acid, which are necessary for the reduction process …
Potassium dichromate - chemeurope.com
In organic chemistry, potassium dichromate is a milder oxidizer compared with potassium permanganate. It is used to oxidise alcohols. It converts primary alcohols into aldehydes, or into carboxylic acids if heated under reflux .
