oxidation of 1,methyl-propanone with the presence of KMnO4 & conc H2SO4 under heat.
The oxidation of 1-methyl-propanone (also known as methyl isobutyl ketone or MIBK) with the presence of potassium permanganate (KMnO4) and concentrated sulfuric acid (H2SO4) under heat is a chemical reaction that results in the formation of a carboxylic acid.
Here is the reaction equation for the oxidation of 1-methyl-propanone:
1-methyl-propanone + KMnO4 + H2SO4 → carboxylic acid + MnSO4 + K2SO4 + H2O
To understand the steps involved in this reaction, let's break it down:
1. First, you mix the 1-methyl-propanone (MIBK) with concentrated sulfuric acid (H2SO4) and heat the mixture. The presence of concentrated sulfuric acid acts as a catalyst and facilitates the oxidation process.
2. Then, you slowly add potassium permanganate (KMnO4) to the mixture. KMnO4 is a strong oxidizing agent and reacts with MIBK, causing it to undergo oxidation.
3. As a result of the oxidation, the MIBK molecule gains additional oxygen atoms, breaking carbon-carbon bonds and forming a carboxylic acid. The exact carboxylic acid formed will depend on the specific reaction conditions and the structure of the MIBK molecule.
4. The reaction also produces manganese sulfate (MnSO4), potassium sulfate (K2SO4), and water (H2O) as byproducts.
It's important to note that this reaction is an example of an oxidation reaction and is commonly used in organic chemistry laboratories to convert ketones into carboxylic acids. The reaction conditions, such as temperature and concentration, can be adjusted to achieve the desired yield and selectivity.
