<p>The invention relates to a composition of mixed alkylated triphenyl phosphate esters comprising no less than 65 % to about 100 %, by weight, monoalkylphenyl diphenyl phosphate, up to about 30 %, by weight, dialkylphenyl phenyl phosphate, up to about 3 %, by weight, trialkylphenyl phosphate, and up to about 5 %, by weight, triphenyl phosphate. The alkyl moieties can be isopropyl, isobutyl tertiary-butyl, isoamyl, tertiary-amyl, isooctyl and/or isononyl. The fluids prepared according to the previously described method show unusually low air entrainment values of less than 180 seconds, and as low as 20 seconds, and have a content of triphenyl phosphate that typically varies from about 0 to about 5.0 %.</p> |
