How to make acetophenone from benzaldehyde?

Hint: Acetophenone is a methyl ketone that is acetone with a phenyl group in place of one of the methyl groups. It functions as a photosensitizing agent, an animal metabolite, and a xenobiotic, among other things.

Complete answer:
In order to make acetophenone from benzaldehyde, the following reactions take place.
Benzaldehyde undergoes oxidation in the presence of potassium permanganate and sulphuric acid to form benzoic acid. Benzoic acid further reacts with sodium hydroxide to produce sodium salt of benzoic acid that is sodium benzoate. Sodium benzoate further undergoes decarboxylation to produce Benzene.
Furthermore, in the presence of anhydrous aluminium chloride acetophenone is formed.
The reaction takes place as follows:


Additional Information:
Acetophenone is a fragrance ingredient in soaps and fragrances, as well as a food flavouring agent and a solvent for plastics and resins. In humans, acute (short-term) acetophenone vapour exposure can cause skin irritation and transitory ocular damage.
The following are the most prevalent applications of benzaldehyde that make it such an important compound:
The most prevalent application of benzaldehyde is to flavour foods with almond flavouring. It imparts the aroma of almonds to foods and beverages. Benzaldehyde is also used as an ingredient in a variety of scented items to give them a particular odour.
Benzaldehyde is used in industry as an intermediary in the manufacture of a variety of organic chemicals. It's used to make a variety of chemical additives, polymers, and pharmaceuticals.

Note:
Benzaldehyde is normally stable, however it should be stored according to the manufacturer's instructions. It must be kept in a tightly sealed container away from heat and light. It should be maintained away from acids and reducing agents, as well as other reactive chemicals. It's also a good idea to keep this substance under nitrogen.
