Tetrabromobisphenol A bis(dibromopropyl ether) Chemical Properties, Uses, Production

Description

Tetrabromobisphenol A bis(2,3-dibromopropyl) ether is part of the group of Brominated and Chlorinated Flame Retardants. FR-50 is a flame retardant containing both aromatic and aliphatic bromine. It's is designed for use in polyolefin and styrenic resins, providing a UL94 V-2 rating. It can also be applied to polypropylene, to reach a V-0 rating.

Chemical Properties

White powder

Uses

Bis(2,3-dibromopropoxy)tetrabromobisphenol A is a the DBP-based flame retardant for polyolefins and polymers, including PP, high-density polyethylene (HDPE), and low-density polyethylene (LDPE). Bis(2 ,3-dibromopropoxy)tetrabromobisphenol A is also used in fabricated plastic sheet materials for application in the formation of a part of many electrical cabinets.

Uses

tetrabromobisphenol A bis(dibromopropyl ether),OBE, is an additive brominated flame retardants, can be widely used in polyolefin (pp), high impact polystyrene (HIPS) and ABS and other products.

Flammability and Explosibility

Flammable

Synthesis

Add bromine reaction and matting: in reactor, squeeze into 780 kilograms of chloroforms, get tetrabromo bisphenol A diene propyl ether and be dissolved in the chloroform solvent for 400 kilograms.Squeeze into 216 kilograms of bromines after in the bromine header tank, adding 18 kilograms of aluminum bromides.Start reactor and stir, open the reactor coolant valve, keep material in reactor, open bromine header tank baiting valve, in reactant, splash into bromine and catalyzer in the material continuously at 15～25 ℃.Drip bromine and catalyzer and finish off-response still coolant valve.40～45 ℃ of slakings 1 hour.Add mass percent in the reactor and be 150 kilograms of 3% soda ash salt brine solutions, stirred 1 hour, tell washing soda salt solution, the clear water secondary washing is added in the back, tells washing water, makes the chloroformic solution of two (2, the 3-dibromopropyl) ethers of tetrabromo-bisphenol.Spraying desolventizing and finished product operation: in the washing still, inject 1200 kilograms in clear water, open the steam system and the stirring of washing still, keep near 60 ℃ of the water lotion temperature.Open the coolant system of atomizing precipitation tower middle part water vapor intake valve and atomizing precipitation top of tower interchanger.Open the tetrabromo-bisphenol two (2 of atomizing precipitation tower top injector, the 3-dibromopropyl) ether chloroformic solution spraying feed valve, open baiting valve and still bottomspump at the bottom of the still of reactor, in atomizing precipitation tower, spray tetrabromo-bisphenol two (2, the 3-dibromopropyl) ether chloroformic solution, adjust two (2, the 3-dibromopropyl) the ether chloroformic solution input speeds of material pump discharge pressure and tetrabromo-bisphenol, make spray effect reach necessary requirement.Two (2, the 3-dibromopropyl) the ether particle gravitates of tetrabromo-bisphenol that remove behind the chloroform solvent fall into the washing still, keep washing still temperature of charge and continue 2 hours for 60 ℃, finish spray atomization, the imitative solvent of dechlorination, granulation powder process, matting process.Open the baiting valve of washing at the bottom of the still, emit in the washing still material and go into whizzer, carry out centrifuge dripping, filtration cakes torrefaction, make 712 kilograms of two (2, the 3-dibromopropyl) ether finished products of tetrabromo-bisphenol, yield 98.8%.Analysis records 109～111 ℃ of fusing points, and the HPLC purity assay is 98.37%, and the GB2917-82 congo red method records 228 ℃ of heat decomposition temperatures.
