Application | hexabromobenzene as additive flame retardant, suitable for polyethylene, polypropylene, polystyrene, ABC resin, epoxy resin, polyamide, polyester, etc. With antimony trioxide (2-3):1 in combination, there is a synergistic effect. Hexabromobenzene flame-resistant effect is good, little effect on the physical properties of the resin. This product has good heat resistance and can be effectively used for plastics to be molded at high temperature in South Africa. With the resin phase; Good capacitive, high melting point, molding smooth appearance. The product may also be used as a filler. used as chemical reagent |
production method | results from the reaction of benzene with Excess bromine. Benzene is added dropwise to iron powder or aluminum powder as a catalyst. After completion of the addition of benzene, the Reflux reaction was continued until no more hydrogen bromide was evolved. The bromine was distilled off, a small amount of water was added, and unreacted bromine was neutralized with base under stirring. Hexabromobenzene is obtained by filtration, washing and drying. |
