Chemical name: Ethyltriphenylphosphonium Acetate
CAS number: 35835-94-0
Description and Features
Catonium ETPAAC (Ethyltriphenylphosphonium Acetate) is a colourless to slightly yelow liquid, its chemical formula is C22H23O2P. ETPAAC is a quaternary phosphonium salt available in 70% by weight solution in methanol. One mole of acetic acid is bound to each mole of ETPAAC. The material is mainly used for the advancement and curing of phenolic based epoxy resins and as a phase transfer catalyst.
Ethyltriphnylphosphonium Acetate also known as ETPAAC, ETPAACc and TEPA.
Compared to amines, imidazoles and quaternary ammonium salts CatOnium ETPAAC 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.
