CHARACTER

diethyl phthalate (DEP), chemical formula C12H14O4, is a colorless to slightly yellow transparent oily liquid with aromatic odor, commonly used as an organic solvent and plasticizer. DEP has good solubility and volatility, can be miscible with a variety of organic solvents, is an important raw material for the manufacture of coatings, inks, resins and adhesives. As a plasticizer, DEP can improve the flexibility, cold resistance and processing performance of plastics, and is widely used in the production of polyvinyl chloride (PVC) products. In addition, DEP is also used in the manufacture of fragrances, dye intermediates and as a solvent in the laboratory. As a multifunctional organic compound, diethyl phthalate is widely used in chemical, plastic, ink and other industries.

APPLICATIONS

(1) Diethyl phthalate can be used as a plasticizer, especially for plastics and cellulose resins, to improve their flexibility and processability. It is mainly with cellulose acetate, polymethyl methacrylate, polystyrene and other resins have good compatibility, is an important modifier of these materials.

(2) The compound can also be used as a solvent and lubricant. In the manufacture of cosmetics and perfumes, it can be used as a solvent and fixative for fragrances, which can enhance the durability and stability of fragrances. It is also used in the manufacture of detergents and spray insecticides.

(3) Diethyl phthalate as a frother in the flotation of non-ferrous metal mines can improve the flotation efficiency. It is also a stationary liquid for gas chromatography and is used for chemical analysis.

(4) In addition, it can also be used as an alcohol denaturing agent to prevent alcohol from being illegally used as drinking alcohol. In the manufacture of adhesives, diethyl phthalate can improve the adhesion of polyvinyl acetate and enhance the performance of adhesives.

(5) In pharmaceutical manufacturing, diethyl phthalate is also used as a solvent and lubricant to help better mix and shape pharmaceutical ingredients. At the same time, it is also used as a stabilizer for rocket propellants to ensure the stable operation of rocket propulsion systems.
