Description

TCC’s Ethyltriphenyl phosphonium bromide (ETPB) is a white to off-white crystalline powder. Its chemical formula is C2H5P(C6H5)3·Br. It is used as a phase-transfer catalyst in the production of epoxy resins and powder coatings and as a pharmaceutical intermediate.

ETPB is hydroscopic, soluble in water, and stable under ordinary conditions. Synonyms for ETPB are ETPPB, BETP, TEPB, ETPB, and ETPPBr.

Phosphonium describes a univalent radical, PH4. Quaternary phosphonium salts, obtained from tertiary alkylphosphines with the treatment with alkyl or aromatic halides, are replacing phase transfer catalysts and biocides functions for quaternary phosphonium salts due to more effective performance and higher thermal stability. Phosphonium salts are used as epoxy curing agents. A variety of phosphine transition metal complexes including chiral complexes are synthesized as the very reactive and versatile homogeneous catalysts and stereospecific as well.
