The nature and use
of fumaric acid in the field of chemical production raw materials
1. Introduction

Fumaric acid is an important organic acid with a wide range of uses. In the field of chemical production raw materials, fumaric acid has attracted much attention because of its unique chemical properties. In this paper, the properties and uses of fumaric acid are discussed in detail.

2. The properties of fumaric acid

1. Physical properties: Fumaric acid is a white crystalline powder with a melting point of 168-172°C and a boiling point of 295°C. It is easily soluble in organic solvents such as hot water, ethanol and ether, and slightly soluble in cold water.

2. chemical properties: fumaric acid has two carboxylic acid groups, with strong acidity, can react with alkali to generate salt. At the same time, fumaric acid also has unsaturated double bonds, can occur addition, oxidation, polymerization and other reactions.

3. the use of fumaric acid

1. synthetic resins and plastics: fumaric acid can be used as a monomer, copolymerized with other monomers to generate a variety of polymers, such as polyester, polyamide, etc., for the production of plastics and resins.

2. Food additives: Fumaric acid can be used as a food additive to regulate the acidity and taste of food, and can also be used as a preservative to extend the shelf life of food.

3. Pharmaceutical intermediates: Fumaric acid can be used as pharmaceutical intermediates for the production of various drugs, such as antibiotics, antipyretic analgesics, etc.

4. Dyes and pigments: Fumaric acid can be used as an intermediate for dyes and pigments in the production of various colored substances.

IV. Production methods of fumaric acid

The production methods of fumaric acid mainly include chemical synthesis and biological fermentation. Chemical synthesis method is mainly through the hydrolysis of maleic anhydride to obtain fumaric acid, and the law of biological fermentation is to obtain fumaric acid through microbial fermentation. The two methods have their own advantages and disadvantages, and can be selected according to actual needs.

5. the market prospect of fumaric acid

With the continuous development of science and technology, fumaric acid is more and more widely used in the field of chemical production raw materials, and the market demand is also increasing. In the future, with the improvement of environmental awareness and the requirements of sustainable development, the production of fumaric acid by biological fermentation will become the mainstream, and more new applications will emerge. Therefore, the market prospect of fumaric acid is very broad.

6. Conclusion

fumaric acid, as an important organic acid, has a wide range of uses and unique properties, especially plays an important role in the field of chemical production raw materials. In the future, with the continuous progress of technology and the expansion of application fields, the market prospect of fumaric acid will be broader.
