Oxidation of Ph3 By Redox Polymers - Convenient Method For Synthesis Organic Phosphorus Compounds
Keywords:
Redox ?olymer, Quinone, Anion Exchanger, Phosphine, Oxidation, Green ChemistryAbstract
The synthesis of aminoquinoid redox polymers and their oxidation of a toxic gas of phosphine is described. An effect of the nature of solvents, catalysts, relationship between initial components, temperature and time modes of condensation of reactants on the yield and properties of redox polymers formed have been researched into by way of chemical modification of industrial weak-basic anion exchangers by quinones and their derivatives, in an environment similar to green chemistry positions. Synthesized redox-polymers have been tested as oxidants of toxic gas phosphine. The process is based on the oxidation of phosphine by quinones and redox polymers on their basis. Molecular iodine is used as a catalyst. Two-, three-, four- and multicomponent systems are studied in order to determine optimal conditions of the oxidation of phosphine. The rate and selectivity of reaction were monitored by the absorption of ??3. As alcohols used aliphatic alcohols: BuOH, PrOH, EtOH, MeOH. Organophosphorus compounds were analyzed by a chromatographic method. Conversion of phosphine constitutes 80-86%.
