Process for preparing the pentaerythritol ester of phosphorohalidous acid

The pentaerythritol ester of phosphorohalidous acid is prepared by reacting pentaerythritol and a trivalent phosphorus trihalide in the presence of a catalyst. The pentaerythritol ester of phosphorohalidous acid is a useful intermediate in the preparation of halogenated organophosphate flame retarda...
