Ethyltriphenylphosphonium acetate Chemical Properties,Usage,Production

Description

Ethyltriphenylphosphonium Acetate, also known as ETPAAC, ETPAACc and TEPA, is a colourless to slightly yellow liquid with the chemical formula C22H23O2P. This quaternary phosphonium salt is available in a 70% by-weight solution in methanol. Notably, one mole of acetic acid is bound to each mole of ETPAAC. Furthermore, the material is mainly used for advancing and curing phenolic-based epoxy resins and serving as a phase transfer catalyst. Compared to amines, imidazoles, and quaternary ammonium salts, Ethyltriphenylphosphonium Acetate has considerably better latency and thermal stability. Further, it offers a low odour, minimal colour formation and controlled reactivity.

Uses

Ethyltriphenylphosphonium acetate is mainly used to advance and cure phenolic-based epoxy resins and as a phase transfer catalyst. It exhibits considerably better latency and thermal stability when compared to amines, imidazoles and quaternary ammonium salts. Furthermore, it has minimal odour, colour formation, and controlled reactivity. It decreases or eliminates side reactions and creates longer, straighter chain epoxy molecules with sharp molecular weight distribution.

Precautions

Store Ethyltriphenylphosphonium Acetate in a cool, dry, and well-ventilated area to ensure compliance with legal requirements. Keep ETPAAC away from heat sources and oxidizing agents to maintain safety and stability.
