How to Make Acetone: From Basic Concepts to Industrial Applications

Acetone (Acetone), whose chemical formula is C≡H≡O, is an important organic solvent, which is widely used in the fields of chemical industry, medicine, paint and cosmetics. How to make acetone? This process involves not only small-scale laboratory synthesis, but also large-scale industrial production. This article will introduce the production method of acetone in detail and discuss its wide application in the chemical industry.

1. What is acetone?

Acetone is a colorless, volatile and highly soluble solvent. It is an intermediate in many chemical reactions and is often used to dissolve grease, resin, paint, glue and other substances. As an organic solvent, acetone is not only widely used in industry, but also one of the reagents commonly used in laboratories. Its good solubility and low boiling point make it an important position in a variety of industries.

2. How to make acetone? -- Laboratory synthesis method

In the laboratory, acetone is usually synthesized by certain chemical reactions. Common laboratory synthesis methods are the following:

2.1 through propylene oxidation

A common method of preparing acetone in the laboratory is the oxidation of propylene (Celevated) in air. At high temperatures, propylene reacts with oxygen to form acetone. Specific reaction is as follows:

[\text{C₃H₆} \text{O₂} \rightarrow \text{C₃H₆O}]

this method is relatively simple, but requires higher reaction temperatures and catalysts.

2.2 PROPIONIC ACID DEHYDRATION REACTION

Another way to prepare acetone is to obtain acetone by dehydration starting from propionic acid (Celevated). This reaction usually requires a catalyst and high temperature conditions to remove the water molecule from the propionic acid molecule to form acetone.

3. How to make acetone? -- Industrial production method

In industrial production, the synthesis of acetone often requires large-scale, cost-effective production processes. At present, acetone mainly has the following industrial production methods:

3.1 by catalytic oxidation of propylene

The catalytic oxidation of propylene is one of the most commonly used acetone production methods in industry. This process reacts propylene with oxygen in the air over a catalyst at high temperature to produce acetone and other by-products. The advantage of this process is that the raw material propylene is abundant and the cost is low, but the reaction conditions are relatively harsh.

3.2 by the isophorone process for the production of acetone

Another industrial process for the production of acetone is the isophorone process (Cumene process). This method is the final synthesis of acetone by the reaction of isophorone (cumene, C≡H≡C≡H≡CH) with oxygen. This method is often used for the joint production of acetone and benzene in large-scale production. The reaction efficiency of this process is high, and the by-products are less, which is suitable for large-scale production.

4. Acetone application

Acetone is widely used in the chemical industry. Its characteristics as a solvent make it play an important role in many fields. The following are the main application areas of acetone:

4.1 Chemical Industry Solvents

Acetone is widely used as a solvent in the chemical industry and is capable of dissolving many organic compounds. It is often used in the production of paints, coatings, cleaners, glues and other products. Due to the strong volatility of acetone, it will evaporate quickly after use, so it will not leave a residue.

4.2 Pharmaceutical Industry Applications

Acetone is also used in the pharmaceutical industry, especially in the extraction and purification of drugs. It can be used to dissolve and separate pharmaceutical components, and as an intermediate in the production process of certain drugs.

4.3 cosmetics in the important ingredients

Acetone is also widely used in the cosmetics industry, especially in products such as nail polish removers and cosmetic cleansers. It can effectively remove nail polish and cosmetics, and due to its volatile characteristics, it will not cause excessive residue on the skin after use.

5. How to choose suitable acetone production method?

When choosing a production method for acetone, companies need to consider a number of factors, including raw material sources, costs, reaction conditions, and by-product treatment. In the laboratory, the synthesis method of acetone is relatively simple, but industrial production needs to rely on more efficient and economical production process.

How acetone is made depends on the scale of production and demand. Whether it is small-scale laboratory synthesis or large-scale industrial production, choosing the right method will help improve production efficiency and reduce costs.

6. Summary

As an important chemical raw material, acetone has many production methods, including laboratory oxidation and industrial large-scale catalytic oxidation or isophorone method. Regardless of the environment in which it is produced, the wide application of acetone makes it play an important role in many fields. With an in-depth understanding of how to make acetone, companies and researchers can choose the best production process according to their needs, so that they can be used in related industries more efficiently.
