摘要 |
<p>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<o>C to about 250<o>C at a pressure sufficiently less than 5 kPa to evaporate about 5% to about 30% of the composition.</p> |
