Title (DE) VERFAHREN ZUR GEWINNUNG VON PHOSPHORIGSÄURE-BIS-(2,4-DI-TERT.-BUTYL-PHENYL)-ESTER-HALOGENIDEN
(EN) PROCESS FOR OBTAINING PHOSPHOROUS ACID-BIS-(2,4-DI-TERT.-BUTYL-PHENYL) ESTER HALIDES
(FR) PROCEDE DE PREPARATION D'ESTER-HALOIDES D'ACIDE PHOSPHOREUX BIS-(2,4-DI-TERT.-BUTYLE-PHENYLE)
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Gewinnung von Phosphorigsäure-bis(2,4-di-tert.-butyl-phenyl)-ester-halogeniden der Formel (I), dadurch gekennzeichnet, dass man ein Phosphorigsäure-2,4-di-ter.-butyl-phenyl-ester-dihalogenid der Formel (II) in Gegenwart einer katalytisch wirkenden, Stickstoff und/oder Phosphor enthaltenden Verbindung auf 130 bis 280 °C erhitzt und das so durch Disproportionierung entstehende Phosphortrihalogenid aus dem Reaktionsgemisch entfernt.
(EN) The invention relates to a process for obtaining phosphorous acid-bis-(2,4-di-tert.-butyl-phenyl) ester halides of formula (I), in which a phosphorous acid-2,4-di-tert.-butyl-phenyl ester dihalide of formula (II) is heated in the presence of a compound containing nitrogen and/or phosphorus and acting as a catalyst to 130 - 280 °C and removing the phosphorus trihalide produced by disproportionation from the reaction mixture.
(FR) L'invention concerne un procédé de préparation d'ester-haloïdes d'acide phosphoreux -bis(2,4-di-tert.-butyle-phényle) de formule (I), caractérisé par le fait qu'on chauffe entre 130 et 280 °C un ester-dihaloïde d'acide phosphoreux 2,4-di-tert.-butyle-phényle de formule (II) en présence d'un composé à action catalytique contenant de l'azote et/ou du phosphore et qu'on retire du mélange réactionnel le trihaloïde de phosphore résultant du disproportionnement.
