Tetraphenylphosphonium bromide Chemical Properties,Usage,Production
Chemical Properties
white to off-white crystalline powder
Uses
Tetraphenylphosphonium bromide is a supporting electrolyte for the electroreduction of buckminsterfullerene. It is used to extract heavy metals from aqueous solution as ion-association complexes
Uses
- Tetraphenylphosphonium bromide is also known as TPP, TPP-Br, TPPB and TPPBr.Tetraphenylphosphonium bromide is a quaternary phosphonium salt mainly used in pharmaceuticals, as accelarator for fluoroelastomers , adhesion promotor for fluoroelastomers and curative of polyacrylate polymers which extends the shelf life of the compound and decreases the mould fouling. This material is highly soluble in water and slightly soluble in alcohols.
- Tetraphenylphosphonium bromide is a supporting electrolyte for the electroreduction of buckminsterfullerene.
- It is used to extract heavy metals from aqueous solution as ion-association complexes.
- Recently, tetraphenylphosphonium bromide (TPPB) has been used to remove technetium from some radioactive waste streams.
Synthesis
Add 786g of triphenylphosphine, 702g of bromobenzene and 196g of catalyst (including 25g of nickel chloride and 171g of zinc chloride) sequentially to a 5L reactor, react at 190C for 10~12h and then cooled down to 100C. Then pure water was added to the above reactor, and the reaction solution was kept warm with stirring for 3h and then stood until stratified, and then partitioned and the organic phase was recovered and used for the next batch of reuse; The aqueous phase was recovered and further stirred and cooled to room temperature, then filtered and washed until no catalyst ions were detected in the fresh filtrate, the resulting filtrate was collected, and the water was evaporated to dryness to recover the catalyst. In addition, the resulting filter cake was dried at 70~140C to obtain 982 g of white tetraphenylphosphonium bromide, with a product yield of 82 %, a catalyst recovery of 92 % and a bromobenzene recovery of 96 %.
