1, cyclohexanone was first oxidized by acidic potassium permanganate.

2. Then replace the hydrogen atom with bromine water.

3. Then replace bromine atom with methanol.

4. Then the hydroxyl group is oxidized by potassium permanganate to obtain two carboxylic acids.

Cyclohexanone is an organic compound, which is a saturated cyclic ketone with carbonyl carbon atoms in the six-membered ring. Colorless and transparent liquid, with earthy smell, and mint smell when containing trace phenol. The impurities are light yellow, which is water-white to grayish yellow and has a strong pungent smell. The explosive electrode mixed with air is the same as the open-chain saturated ketone. Cyclohexanone has carcinogenic effect, and it is mainly used as raw material and solvent for organic synthesis in industry, such as soluble nitrocellulose, coatings and paints.

Adipic acid, also known as fatty acid, is an important organic dibasic acid, which can undergo salt-forming reaction, esterification reaction, amidation reaction and so on. And can be condensed with diamines or diols to form polymers and the like. Adipic acid is an important dicarboxylic acid in industry, which plays an important role in chemical production, organic synthesis industry, medicine and lubricant manufacturing, and its output ranks second among all dicarboxylic acids.
