Chemical properties:
Colorless liquid, crystallizes at low temperature. Miscible with ethanol, ether, benzene, acetone, insoluble in water.
Uses:
1. Used as raw material for the production of polyester fibers and resins, coatings, dyes and pesticides
2. Used as a standard substance and solvent for chromatographic analysis, and also used in organic synthesis for solvents for rubber and paints and additives for aviation fuel
3. Used to produce terephthalic acid, and then to produce polyester resins such as ethylene terephthalate and butanediol terephthalate. Polyester resin is the raw material for the production of polyester fibers, polyester sheets, and polyester hollow containers. Polyester fiber is currently the largest synthetic fiber in my country. It is also used as a raw material for coatings, dyes and pesticides.
4. Solvent. Organic synthesis. Gas chromatography analysis standard.
