Succinic acid, also known as succinic acid, is an important organic chemical raw material widely used in medicine, food, agriculture and other industrial fields. This article will introduce the properties of succinic acid, production methods and applications in various fields.

1. the nature of succinic acid

succinic acid is a colorless crystal or white powder, with a strong sour taste. Its molecular formula is C4H6O4, structural formula is HOOC-CH2-CH2-COOH. Succinic acid has strong acidity and reducibility, and can react with many substances, such as alcohols, amines, metals, etc. In addition, succinic acid also has good thermal stability and water solubility.

2. the production method of succinic acid

succinic acid production methods are mainly chemical synthesis and biological fermentation.

1. Chemical synthesis method: succinic acid is mainly prepared by oxybutylene anhydride or succinic dialdehyde. However, this method is complicated and costly.
2. Biological fermentation: The use of microbial fermentation to produce succinic acid has the advantages of readily available raw materials, low cost, and environmental protection, and has gradually become the main production method.

3. succinic acid application

1. pharmaceutical field: succinic acid in the field of medicine has a wide range of applications, can be used as a drug raw materials or excipients. For example, succinic acid can be used in the production of antibiotics, vitamin B family and other drugs.
2. Food field: As a food additive, succinic acid can be used to adjust the taste and sour taste of food, and is often used as a sour agent and preservative.
3. Agricultural field: Succinic acid can be used to produce pesticides and plant growth regulators, which can help to improve crop yield and quality.
4. Other industrial fields: Succinic acid can also be used in the production of dyes, spices, plastics and other chemical products, as well as metal surface treatment agents.

In short, as an important organic chemical raw material, succinic acid has been widely used in various fields. With the development of science and technology, the production process of succinic acid will continue to be optimized, and its application in various fields will continue to expand.
