| Questions and Answers (Q&A) | Back Directory | [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.
