ABSTRACT:
A mixed phenyl/mesityl phosphate ester composition that is useful as a fire retardant additive, having a phosphorus content of from about 8.2% to about 8.4% is prepared by reacting with agitation at about 120.degree. C. to 130.degree. C. distilled still bottom phenols with phosphorus oxychloride in the presence of a Friedel-Crafts catalyst to form a reaction product containing a substantial quantity of monoaryl phosphodichloridate and diaryl phosphochloridate. This reaction product is then further reacted at an elevated temperature with sufficient phenol to form a triaryl phosphate ester mixture. The mixed phenyl/mesityl phosphate ester so obtained remains a liquid at room temperature over a substantial period of time.
