Biological redox reactions of alcohols and phenols.   Alcohol oxidation reactions are widely used for the preparation of aldehydes and ketones. The electrolysis of alcohols to carbonyl compounds have been underutilized owing to low efficiency. Herein.

The overall type of reaction is the same as that in the conversion of isopropyl alcohol to acetone. Tertiary alcohols (R 3 COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms. The oxidation reactions we have described involve the formation of a carbon-to-oxygen double bond.   Oxidation and Reduction in Electrolytic Cells In an electrolytic cell, an electric current is passed through an electrolyte using electrodes. The electrolyte may be a molten ionic compound or an aqueous solution containing ions. The electrodes are usually inert conductors such as platinum or carbon. Sometimes active electrodes such as copper are used. Chapter 11 Lecture Notes 1 Chapter 11 Lecture Notes: Alcohols, Ethers, Aldehydes, and Ketones Educational Goals 1. Given the structure of an alcohol, ether, thiol, sulfide, aldehyde, or ketone molecule, be able to give the systemic names and vice versa. In the third and final step of the oxidation mechanism, another chromate ester is formed from the hydrated aldehyde in step 2, which then rapidly breaks down to form our final carboxylic acid product.

An excess of the oxidizing agent must be used, and the aldehyde formed as the half-way product should remain in the mixture. The alcohol is heated under reflux with an excess of the oxidizing agent. When the reaction is complete, the carboxylic acid is distilled off. The full equation for the oxidation of ethanol to ethanoic acid is as follows. Alcohol - Alcohol - Reactions of alcohols: Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.
