ABSTRACT:
The invention is a novel composition of alkylated phenyl phosphate esters comprising by weight 1% to 20% trialkylphenyl phosphate, 10% to 50% dialkylphenyl monophenyl phosphate, 15% to 60% monoalkylphenyl diphenyl phosphate and less than 2% triphenyl phosphate and a process for preparing the composition comprising passing the composition at least once through a thin film evaporator at a temperature of about 200.degree. C. to about 250.degree. C. at a pressure sufficiently less than 5 kPa to evaporate about 5% to about 30% of the composition.
