Title (EN) METHOD FOR PRODUCING ORGANOPHOSPHITES
(FR) PROCEDE DE PRODUCTION DE PHOSPHITES ORGANIQUES
(DE) VERFAHREN ZUR HERSTELLUNG VON ORGANOPHOSPHITEN
Abstract:
(EN) The invention relates to a method for producing compounds of formula X(1-a) R2a P (OR1)2 (I) or X(2-a) R2a P (OR1) (II), wherein X: Cl, Br, J; R1: an organic radical; R2: an organic radical; and a: 0.1, characterised in that a) a compound (III) of formula PX(3-a)R2a is reacted with a compound (IV) of formula R1OH at temperatures of 10 to 200 °C, the molar ratio of the X radicals used to compound (IV) being 1:10 to 10:1, to obtain a mixture (V) containing compound (I) and compound (II), b) compounds (I) and (II) are separated from the mixture (V) and c) compound (I) or compound (II) is returned to step (a).
(FR) L'invention concerne un procédé de production de composés de la formule X(1-a) R2a P (OR1)2 (I) ou X(2-a) R2a P (OR1) (II) où: X = Cl, Br, J; R1 représente un reste organique; R2 représente un reste organique; a vaut 0,1. L'invention est caractérisée en ce que a) l'on fait réagir un composé (III) de la formule PX(3-a)R2a avec un composé (IV) de la formule R1OH à des températures comprises entre 10 et 200 °C pour obtenir un mélange (V) contenant le composé (I) et le composé (II), le rapport molaire Restes X utilisés/Composé (IV) étant de 1:10 à 10:1 ; b) on sépare les composés (I) et (II) du mélange (V) et c) on renvoie le composé (I) ou le composé (II) à l'étape (a).
(DE) Verfahren zur Herstellung von Verbindungen der Formel X(1-a) R2a P (OR1)2 (I) oder X(2-a) R2a P (OR1) (II) mit: X: Cl, Br, J; R1: organischer Rest; R2: organischer Rest; a: 0,1; dadurch gekennzeichnet, dass man a) eine Verbindung (III) der Formel PX(3-a)R2a mit einer Verbindung (IV) der Formel R1OH bei Temperaturen im Bereich von 10 bis 200 °C umsetzt, wobei das molare Verhältnis der eingesetzten Reste X zu Verbindung (IV) 1:10 bis 10:1 beträgt, unter Erhalt einer Mischung (V) enthaltend Verbindung (I) udn Verbindung (II), b) aus der Mischung (V) die Verbindungen (I) udn (II) abtrennt und c) Verbindung (I) oder Verbindung (II) in Schritt (a) zurückführt.
