Tetrakis(hydroxymethyl)phosphonium chloride (THPC) is an organophosphorus compound with the chemical formula [P(CH2OH)4]Cl. 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 microbiocide in commercial and industrial water systems. http://article.sapub.org/10.5923.j.chemistry.20241302.02.html

Process for preparation of quaternary ammonium and phosphonium …

WebA process is provided for obtaining quaternary ammonium or phosphonium substituted carbonic acid esters. The first step involves reacting the hydroxyl predecessor compound of the ester with phosgene in an aprotic organic solvent to obtain a solution of chloroformate/hydrogen chloride complex. WebAbstract. Dynamic TGA studies of phosphonium ionic liquids have reported thermal stabilities of 300 °C or higher for these compounds. This is often an overestimation of the … parks in kitsap county
