How acetone reacts with concentrated sulfuric acid: detailed analysis and application

as a common organic solvent, acetone is widely used in chemical, pharmaceutical, coating and other industries. As a strong acid, concentrated sulfuric acid (H₂) has a strong dehydration and catalytic effect. The reaction of acetone with concentrated sulfuric acid is a common and important reaction in organic chemistry, and understanding this reaction is not only helpful to chemical laboratory operations, but also of great significance to chemical industrial production. How does acetone react with concentrated sulfuric acid? We will analyze in detail from three aspects: reaction principle, reaction process and application.

PRINCIPLES OF ACETONE AND CONCENTRATED SULFURIC ACID REACTION

The core principle of the reaction of acetone with concentrated sulfuric acid mainly involves acid catalysis and dehydration reaction. The strong acidity of concentrated sulfuric acid enables it to effectively activate the carbonyl group (C = O) in the acetone molecule, making it more active and prone to subsequent reactions. In the reaction of acetone with concentrated sulfuric acid, the carbonyl group of acetone will attract the proton (H +) in concentrated sulfuric acid, forming a transition state. This process will change the molecular structure of acetone, and then enter the next reaction stage.

Reaction Process of Acetone and Concentrated Sulfuric Acid

When acetone reacts with concentrated sulfuric acid, the specific steps of the reaction are as follows:

1. Protonation process: Under the action of concentrated sulfuric acid, the carbonyl group (C = O) of acetone accepts a proton (H₂) to form a transition state, resulting in a positively charged intermediate.

2. Water molecule removal: On the basis of the transition state, acetone molecules remove water molecules to form an olefin intermediate. At this time, the occurrence of the dehydration reaction significantly increases the activity of the reaction.

3. Isomerization to Products: Upon further reaction of this intermediate, different products may be formed. In general, the reaction of acetone with concentrated sulfuric acid mainly produces propylene (Celevated) and water. As one of the important industrial raw materials, propylene is widely used in the synthesis of polypropylene and other chemicals.

It should be noted that the reaction of acetone and concentrated sulfuric acid is an acid-catalyzed reaction, and the reaction conditions such as temperature and concentration of concentrated sulfuric acid will affect the formation of the product.
