The properties and uses
of dibasic esters in the field of raw materials for chemical production
abstract:

this paper introduces in detail the properties and uses of dibasic esters in the field of raw materials for chemical production. Through the description of the physical and chemical properties of the divalent esters, as well as their applications in various chemical production processes, the importance and universality of this compound are demonstrated.

1. Introduction

dibasic ester is an important organic compound, widely used in the field of chemical production raw materials. Because of their unique physical and chemical properties, diesters play an important role in plastics, fibers, coatings, solvents and many other chemicals.

2. properties of dibasic ester

1. physical properties: dibasic ester is usually colorless transparent liquid, with elegant fragrance. It has a higher boiling point and lower vapor pressure, so it has a higher flash point and ignition point, and is relatively safe to use.
2. Chemical properties: Divalent acid esters have ester groups and can be hydrolyzed, alcoholysis, aminolysis and other reactions. In addition, it can also carry out ester exchange reaction, and alcohol, acid, amine and other compounds to generate new ester compounds.

3. the use of dibasic acid esters

1. Plastics and fibers: Dibasic acid esters are important raw materials for many plastics and fibers. For example, it can be used to produce polyester fibers, which have excellent wrinkle resistance, elasticity and dimensional stability, and are widely used to make clothing and household items.
2. Coatings: Divalent acid esters can be used as solvents and film-forming substances for coatings. It has excellent solubility and film-forming properties, which can improve the adhesion and weather resistance of the coating.
3. Solvent: Divalent acid ester is an excellent solvent, which can be used to dissolve many organic compounds, such as resins, inks, dyes, etc.
4. Other chemicals: In addition to the above uses, divalent esters can also be used to produce plasticizers, stabilizers, antioxidants and other chemicals.

4. conclusion

dibasic esters are widely used in the field of chemical production raw materials, and their properties and uses are of great significance to chemical production. With the continuous development of science and technology, the application field of divalent esters will continue to expand, bringing more convenience to human production and life.
