introduction
2,4, 6-tribromophenol is a multi-purpose brominated flame retardant. It can not only be used as a reactive flame retardant for epoxy resin and polyurethane and other resins, but also contains brominated polyphenylene ether, The intermediate of new high-performance flame retardants such as phosphite and phosphate ester; and it can be used as a preservative for wood, paper, etc., and can also be used as a component of compound flame retardant.
chemical properties
White needles form prismatic crystals. Melting point 95-96 ℃ (sublimation), boiling point 244 ℃, relative density 2.55. Soluble in alcohol, chloroform, ether and caustic solution, almost insoluble in water, sweet.
use
1, for the preparation of disinfection antiseptic tribromophenol bismuth, etc. Tribromophenol can be formed into poly 2, 6-dibromophenyl ether by solution polycondensation or aqueous phase precipitation polycondensation. This is a newly developed flame retardant, which can be used in engineering plastics such as nylon 66, thermoplastic polyester and modified polyphenylene ether, as well as high impact polystyrene and ABS resin.
2. Reactive flame retardant, suitable for epoxy resin, polyurethane and other plastics
3. To be used in the production of high molecular weight brominated epoxy resin
production method
from the bromination of phenol.
