PHOSPHATE ESTER SYNTHESIS WITEIOUT PHOSPHORYLATION CATALYST ABSTRACT OF THE DISCLOSURE: Triarylphosphates are prepared by phosphorylation of alkylphenols without use of phosphorylation catalyst. An improved phosphorylation step includes preheating alkylphenol feedstock to 150°C. and completing reaction at 215°C. or above in the presence of a stoichiometric excess of alkylphenol. The absence of phosphorylation catalyst simplifies distillative purification of re- action product by eliminating the need to withdraw puri- fied product as distillate. * * * * * *
