1,2,3,4,5-Pentabromo-6-chlorocyclohexane [ 87-84-3 ]
- Boiling Point
- 190.556 ( ℃ )
Nature: Theoretical amount of 77.8% of bromine, chlorine content of6.82%. White powder. Soluble in acetone, chloroform, aromatic hydrocarbons, insoluble in water. Melting point 190 ~ 195 ℃.
Method: When the reaction system with hydrogen bromide and acrystal produced there, then the reaction has reached the end.
. Benzene, water, and bromine added reactor, on mixing, the external use of fluorescent light, cooling under Walter quantitativechlorine to iron as the catalyst, the reaction temperature is 5 ~ 10 ℃,reaction time 6 ~ 7h.
Uses: In the system of polystyrene foam was added 1.5 to 2.0% (mass). That there is good flame retardant effect. This product isspecial fire retardant polystyrene and polystyrene foam.
