II. This material is highly soluble in water and polarizable solvents. Tetrakis(hydroxyethyl) phosphonium salts are used to produce crease-resistant flame-retardant finishes on cotton textiles and cellulosic fabrics (Hooper, 1973; Hooper et aL., 1976a,b). The cation P(CH 2 OH) 4 + is four-coordinate, as is typical for phosphonium salts. THPS can degrade to a nontoxic substance immediately after use. THPS 75% solution can easily dissolve in water and can be preserved for a long time. Tables I and I1 show that the yields and average molecular weights of polymers with different impressed currents and initial monomer concentrations are almost the same for both ammonium and phosphonium salts. Molecular ferroelectrics owing to their lightweight, flexibility, and phase stability are drawing attention in the fields of flexible electronics, optical devices, and energy materials. BeTPC is a quaternary phosphonium salt mainly used in organic synthesis as a wittig reagent and as a phase transfer catalyst in the production of fluoroelastomers and printing inks. quaternary ammonium and/or phosphonium salts have been extensively studied and applied to a -relevant areas[1]. Molecular Formula H 4 ClP; Average mass 70.459 Da; Monoisotopic mass 69.973915 Da; ChemSpider ID 10645087; More details: Systematic name. A Direct Synthesis of Vinylphosphonium Salts from α-Trimethylsilyl Ylides and Non-Enolizable Aldehydes. The discovery of Ney, Nummy, and Barnes, 1 that 2-pyrrolidone can be polymerized to nylon 4 by basic catalysts, stimulated much subsequent work on the preparation, physico-chemical characterization, and utilization of the polymer. The synthetic strategy for the preparation of high molecular weight chitosan derivatives bearing quaternary phosphonium salts is shown in Scheme 1. Abstract. First published on 15th November 2011.
