What is Dimethyl terephthalate?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Dimethyl terephthalate which has developed particularly rapidly in recent years. Do you know about Dimethyl terephthalate?
- The official answer：Colorless rhombohedral crystals. Insoluble in water, soluble in ether, and hot ethanol. Melting point 140 °C Boiling point 288 °C Density 1,29 g/cm3 Vapour density 1.04 (vs air) Vapour pressure 1.15 mm Hg ( 93 °C) Refractive index 1.4752.
What’s the application of Dimethyl terephthalate?
- Mainly used for the synthesis of polyester fibers, resins, films, polyester paints, engineering plastics, etc. Dimethyl terephthalate is mainly used for the manufacture of polyester resins, which in turn are used to manufacture films and fibers, as well as high-strength polyester insulating paints. Polyester films are mainly used as electrically insulating materials and for the production of films (e.g. as a base material for cinema films, X-ray films, photographic soft films, audiotapes, videotapes, electronic computer tapes, etc.). The most common use of polyester resins is in the manufacture of fibers for use in fabrics, fishing nets, carpets, tire cords, and so on. It is also used to produce the plasticizer dioctyl terephthalate.
