ABSTRACT:
Mixed phosphoric acid ester compositions containing less than 4 weight percent of a triaryl phosphate, from about 10 to about 20 weight percent of an aryl dialkyl phosphate and from about 65 to about 80 weight percent of an alkyl diaryl phosphate are prepared by heating a monohydric alcohol or alkoxy alcohol with a triaryl phosphate, such as triphenyl phosphate, in the presence of a catalytic amount of an alkali metal phenoxide, for example, potassium phenoxide. The mixed phosphoric acid ester composition may be separated from by-products of the reaction by distillation.
