The manufacturing method
of catechol
1. Introduction

Catechol is an important chemical production raw material, widely used in medicine, pesticides, dyes, spices and other fields. Due to its unique chemical properties and wide application, the manufacturing method of catechol has attracted much attention. This paper will introduce the manufacturing methods of catechol, including chemical synthesis and biological method, and analyze their advantages and disadvantages, in order to provide reference for the production of catechol.

2. catechol chemical synthesis method

1. Phenol method: phenol method is a kind of phenol as raw material, after nitrification, reduction, acid solution and other reaction steps of catechol method. This method has mature process and high yield, but a large amount of waste water and waste gas will be produced in the production process, which will cause great pollution to the environment.
2. Benzoic acid method: Benzoic acid method is a method of preparing catechol by oxidation, esterification, reduction and other reaction steps with benzoic acid as raw material. The raw materials of the method are easy to obtain, the reaction conditions are mild, but the yield is low and the production cost is high.
biological method of
3. catechol

1. microbial fermentation: microbial fermentation is a method of catechol produced by microbial metabolism. This method has the advantages of environmental protection and energy saving, but the microbial culture and fermentation process need to be strictly controlled, and the yield is low.
2. Plant extraction method: Plant extraction method is a method of extracting catechol from plants. The method has a wide range of raw materials, but the extraction process is complicated and the yield is not high. The comparative
of different manufacturing methods of

chemical synthesis method has the advantages of high yield and high production efficiency, but a large amount of waste water and waste gas will be produced in the production process, which will pollute the environment. The biological method has the advantages of environmental protection and energy saving, but the yield is low and the production cost is high. Therefore, when selecting the production method of catechol, it is necessary to select a suitable production method in consideration of the actual situation. The application prospect of

5. catechol

catechol as an important raw material for chemical production, has a broad application prospect in the fields of medicine, pesticide, dye, spice and so on. With the continuous progress of science and technology and the continuous expansion of application fields, the market demand for catechol will continue to increase. Therefore, it is of great significance to research and develop efficient and environmentally friendly catechol manufacturing methods.

6. conclusion

This paper introduces two manufacturing methods of catechol, chemical synthesis and biological method, and compares the advantages and disadvantages of different methods. When selecting the manufacturing method of catechol, it is necessary to comprehensively consider the actual situation and select a suitable production method. With the continuous progress of science and technology and the continuous expansion of application fields, the market demand for catechol will continue to increase, so it is of great significance to research and develop efficient and environmentally friendly catechol manufacturing methods.
