How to make acetic acid and its uses

Acetic acid (Acetic Acid), the chemical formula of CH3COOH, is a widely used in industrial, household and medical fields of organic compounds. Its production methods are diverse and its uses are very wide. In this paper, the relevant knowledge of acetic acid will be discussed in detail from two aspects of manufacturing methods and uses.

1. acetic acid manufacturing method

1. 
   by fermentation (traditional method) The fermentation method is the traditional production method of acetic acid, which mainly uses acetic acid bacteria (Acetobacterium) to oxidize ethanol. Specific steps are as follows:

• The ethanol solution was inoculated with acetic acid bacteria.
• At suitable temperature and oxygen conditions, acetic acid bacteria will ethanol oxidation to acetic acid.
The acetic acid is
• separated off by distillation or filtration.
  This method is low cost and suitable for small-scale production, but the production efficiency is relatively low.

1. 
   of Ethylene Oxidation (Modern Industrialized Method) Ethylene oxidation is the main method of industrial production of acetic acid, which has the advantages of high efficiency and low cost.

• Ethylene in the catalyst with oxygen reaction, the formation of acetic acid.
• the reaction conditions are mild and the product purity is high.
  This method is particularly suitable for large-scale production and is widely used in the chemical industry.

Other methods of
1. 
   In addition to the above two methods, acetic acid can also be produced by acetone oxidation, methanol oxidation and other methods. These methods have certain application value under certain conditions, but compared with the fermentation method and ethylene oxidation method, their application range is more limited.

2. acetic acid use

1. 
   for industrial use Acetic acid is widely used in industrial fields, mainly including:

• Solvent: used in paint, coatings, adhesives and other production.
• Vinyl acetate: Used in the production of polyvinyl alcohol (PVA) and acetate.
Chemical intermediates
• : used for the synthesis of acetic anhydride, acetate, etc.
  Acetic acid plays an important role in plastics, textile, pharmaceutical and other industries.

1. 
   for household purposes Acetic acid also has a variety of uses in the home, such as:

• Detergent: diluted acetic acid can be used to clean the kitchen and bathroom, with sterilization and decontamination.
• Food seasoning: As a sour agent, acetic acid is commonly used in food processing, such as vinegar drinks, seasonings, etc.
Home care
• : used to remove scale, clean windows, etc.
  The application of acetic acid in the home reflects its versatility.

1. 
   for medical use In the medical field, acetic acid also has important applications:

• Ointment Ingredients: Used in the preparation of external medicines, such as pain relief ointments and antifungal ointments.
• Disinfectant: Diluted acetic acid solution can be used for skin disinfection.
Dental applications
• : for the treatment and disinfection of dental materials.
  The application of acetic acid in the medical field reflects its sterilization and disinfection characteristics.

3. summary

As an important organic compound, acetic acid has various manufacturing methods, including fermentation, ethylene oxidation and so on. Each method has its own advantages and disadvantages. In terms of application, acetic acid has a wide range of applications in industry, household and medical fields, showing its versatility and importance. With the progress of science and technology, the production efficiency and application range of acetic acid will be further expanded, and make greater contributions to the development of human society.
