Claims
- 1. A composition of mixed alkylated triphenyl phosphate esters, containing at least two of said esters, which composition comprises 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, wherein alkyd moieties are selected from the group consisting of isopropyl, isobutyl, tertiary-butyl, isoamyl, tertiary-aryl, isooctyl and inononyl.
- 2. The composition of claim 1 wherein substantially all of the alkyl moieties are tertiary-butyl.
- 3. The composition of claim 1 wherein substantially all of the alkyl moieties are isopropyl.
- 4. A composition of mixed tertiary-butylated triphenyl phosphate esters comprising no less than about 80% mono-(tert-butylphenyl)diphenyl phosphate, which phosphate comprises from about 40% to about 60% ortho isomer, and from about 60% to about 40% para isomer, up to about 20% di-tert-butylphenyl phenyl phosphate, up to about 2% tri-tert-butylphenyl phosphate, and up to about 5% triphenyl phosphate.
- 5. The composition of claim 4 wherein substantially all of the alkyl moieties are tertiary-butyl.
