Tetrabutylphosphonium chloride 96 2304-30-5 - Sigma-Aldrich
WebFor many phosphonium ions, a very strong base (commonly butyl lithium) is required in order to do the deprotonation. The use of such strong base requires moisture-free conditions such as were required for doing the Grignard reaction.

It is defined as the average percentage of the quaternary phosphonium group (containing three trimethoxyl benzene rings) that crosslinked with the chloromethyl groups. Similarly, 0.891 g or 1.67 mmol TTMPP or TTMPP:CM = 0.90, leads to CL- ... WebA quaternary phosphonium hydroxide, which is represented by the following general formula (II): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 mean independently an alkyl group having 1-8 carbon atoms, a phenyl group or a benzyl group, is prepared by dissolving a quaternary phosphonium halide represented by the following general formula … Textile finishes Tetrakis(hydroxymethyl)phosphonium chloride has industrial importance in the production of crease-resistant and flame-retardant finishes on cotton textiles and other cellulosic fabrics. A flame-retardant finish can be prepared from THPC by the Proban Process, in which THPC is treated with … See more In polyatomic cations with the chemical formula PR 4 (where R is a hydrogen or an alkyl, aryl, or halide group). These cations have tetrahedral structures. The salts are generally colorless or take the color of the anions.
