Abstract
Neutral aromatic triesters of orthophosphoric acid are prepared by the reaction between a pentavalent derivative of phosphorus, P(OR)x Hal(5-x) where x=3, 4 or 5, and R is aromatic, with an aliphatic alcohol, an aromatic phenol or alcohol or an organic hydroxy acid or hydroxy ester acid of phosphorus, ROH being eliminated. The above pentavalent P derivative may be obtained from phosphorus penta- or trichloride generally in situ. The reaction may be used to remove undesired acid organic phosphorus contaminants, e.g. pyrophosphate, from aromatic orthophosphates. In examples, phosphorus pentachloride reacts with phenol to give triphenoxy-phosphorus dichloride which further reacts with ethanol to give triphenyl phosphate; acid organic phosphoric impurities are removed from triphenyl phosphate from other reactions by reaction with pentaphenyl phosphate to give the above product; phosphorus oxychloride reacts with phenol to give triphenyl orthophosphate contaminated with acid esters of phosphorus which are removed with phosphorus pentachloride to give triphenyl orthophosphate.
