Tetrakis(hydroxymethyl)phosphonium chloride

Phosphorous-Based FRs

Published in Asim Kumar Roy Choudhury, Flame Retardants for Textile Materials, 2020

Tetrakis(hydroxymethyl)phosphonium chloride (THPC) is an organophosphorus compound. The cation P(CH2OH)4+ is four-coordinate, as is typical for phosphonium salts. THPC has applications as a precursor to fire-retardant materials, as well as a microbicide in commercial and industrial water systems. THPC has industrial importance in the production of crease-resistant and flame retardant finishes on cotton textiles and other cellulosic fabrics.
