Synthesis of Disodium Phenyl Phosphate

Abstract:Disodium phenyl phosphate was synthesized using phenol, phosphorus oxychloride and sodium carbonate as starting materials. Factors influencing the reactions were studied and optimized. The overall yield was 69.2%. Best results of the phosphoryl reaction were obtained at a molar ratio of 1.0:1.1 (phenol:phosphorus oxychloride) and refluxed for 10 h at 130~140℃. The target product was identified by melting point, elemental analysis and IR. This method has been magnified and industrialized.
Key words:phosphoryl;hydrolysis;neutralization;disodium phenyl phosphate
