Catonium tppbr
Phase Transfer Catalysts
Description
Catonium TPPBr (Tetraphenylphosphonium Bromide) is a white to offwhite, its chemical formula is C24H20BrP. TPPBr 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 also known as TPP, TPPBr, TPPB and TPPBr. Compared to amines, imidazoles and quaternary ammonium salts CatOnium TPPBr features considerable better latency and thermal stability Further it offers a low odor, minimal color formation and controlled reactivity. Availability Europe and United States Provided CatOnium TPPBr is on stock in our local warehouses our lead time is about one week if delivered in 25 KG drums.
