Description

Catonium BTPB (Butyltriphenylphosphonium Bromide) is a white to offwhite powder, its chemical formula is C22H24BrP. BTPB is a quaternary phosphonium salt mainly used in organic synthesis as a wittig reagent and as a phase transfer catalyst in the production of fluoroelastomers, Epoxy Resins and Powder Coatings. This material is highly soluble in water and polarizable solvents. Butyltriphenylphosphonium Bromide is also known as BTPB, BTPPB and TPBPBr. Compared to amines, imidazoles and quaternary ammonium salts CatOnium BTPB 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 BTPB is on stock in our local warehouses our lead time is about one week if delivered in 25 KG fiber drums. Canada, South America, South Africa and other markets can also be served, please contact our sales department for more details.
