VERFAHREN ZUR REINIGUNG VON PHOSPHOROXYCHLORID

Recovered or regenerated phosphorus oxychloride (POCl3) which is contaminated with reactive organic compounds is purified by reaction with 0.1-5 wt% of an organic amine with 1 or 2 tert. nitrogen atoms (I) at the boiling point of the mixture, followed by fractional distillation at normal pressure.
