Description and Features
Catonium BeTPC (Benzyltriphenylphosphonium Chloride) is a white to off-white powder, its chemical formula is C25H22ClP. BeTPC 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 and printing inks. This material is highly soluble in water and polarizable solvents.

Benzyltriphenylphosphonium Chloride is also known as BeTPC, BzTPPCl and TPP-ZC.

Compared to amines, imidazoles and quaternary ammonium salts CatOnium BeTPC features considerable better latency and thermal stability. Further it offers a low odor, minimal color formation and controlled reactivity.

It decreases or eliminates side reactions and creates longer, straighter chain epoxy molecules which have a sharp molecular weight distribution
