Title
(EN) TRANSESTERIFICATION PROCESS
(FR) PROCEDE DE TRANSESTERIFICATION
Abstract
(EN)
The production of esters of oxyacids of pentavalent phosphorus by transesterification of such an ester with an alcohol or phenol is carried out using a basic catalyst which has a base strength of less than (11). Such catalysts give improved conversions compared to more strongly basic catalysts. The preferred processes comprise the conversion of triphenyl phosphate to alkyl/phenyl phosphates by reaction with an aliphatic alcohol in the presence of a medium strength hard base such as potassium carbonate or potassium fluoride.
(FR)
La production d'esters d'oxyacides de phosphore pentavalent par transestérification d'un tel ester avec un alcool ou un phénol est effectuée au moyen d'un catalyseur basique dont la force de la base est inférieure à 11. On obtient avec de tels catalyseurs de meilleures conversions qu'avec des catalyseurs dont la base est plus forte. Les procédés préférés comprennent la conversion de triphényl-phosphate en alkyl/phényl-phosphates par réaction avec un alcool aliphatique en présence d'une base dure de force moyenne telle que du carbonate de potassium ou du fluorure de potassium.
