Combustion Reactions of Ethanol vs. Oxidation Reactions of Ethanol — What's the Difference?
By Tayyaba Rehman — Published on January 2, 2024
Combustion reactions of ethanol involve burning in oxygen to produce carbon dioxide and water. Oxidation reactions of ethanol result in products like acetaldehyde without complete burning.

Key Differences
Combustion reactions of ethanol are a specific type of chemical reaction where ethanol is burned in the presence of an oxidizing agent, usually atmospheric oxygen. When this occurs, the ethanol is completely converted into carbon dioxide and water, releasing energy in the process. This type of reaction is exothermic and is the reason ethanol is used as a fuel in certain applications.
On the other hand, oxidation reactions of ethanol refer to the chemical reactions where ethanol is oxidized but not necessarily burned. In these reactions, ethanol can be converted into various products depending on the conditions and the oxidizing agent. One common product of the oxidation of ethanol is acetaldehyde.
Combustion reactions of ethanol are typically complete reactions that yield the maximum amount of energy from ethanol. They're the reason behind the flame when ethanol burns and are used in various applications where heat or energy is required. These reactions need a sufficient amount of oxygen and are usually characterized by the presence of a flame.
Conversely, oxidation reactions of ethanol might not involve flames. They can occur under various conditions, including enzymatic reactions in the human body. While combustion reactions of ethanol release energy primarily as heat and light, oxidation reactions can be part of more complex biochemical pathways or industrial processes.
