Title (EN) PROCESS FOR PRODUCING ORGANOPHOSPHORUS COMPOUNDS
(FR) PROCESSUS DE PRODUCTION DE COMPOSES DE PHOSPHORE ORGANIQUE
Abstract:
(EN) A process for producing organophosphorus compounds by hydrolyzing the organophosphorus compound of the structural formula (1) by heating in the presence of both an excessive amount of water and an organic solvent which is insoluble in water and inert in the reaction system to thereby give the biphenyl phosphorus compound of the structural formula (2), and then subjecting the compound (2) to cyclodehydration by heating to thereby give the organo-phosphorus compound of the structural formula (3). By this process, the target compound of a high purity and excellent qualities can be produced while dispensing with special chemicals and devices made of special materials.
(FR) Cette invention concerne un processus de production de composés de phosphore organique, lequel processus consiste à hydrolyser le composé de phosphore organique correspondant à la formule (1) par chauffage en présence d'une quantité d'eau excessive et d'un solvant organique insoluble dans l'eau et inerte dans le système de réaction, ceci de manière à obtenir un composé de phosphore biphényle correspondant à la formule structurelle (2). Ce composé (2) est ensuite soumis à une cyclohydratation par chauffage de manière à obtenir un composé de phosphore organique correspondant à la formule (3). Ce processus permet d'obtenir un composé voulu d'une grande pureté et possédant d'excellentes qualités, ainsi que des produits chimiques particuliers et des dispositifs faits de matériaux spéciaux.
