Abstrakt: The possibility of controlling the composition of a mixture of triphenyl phosphate, p-tert-butylphenyl diphenyl phosphate, di(p-tert-butylphenyl)phenyl phosphate, and tri(p-tert-butylphenyl) phosphate, formed by transesterification of triphenyl phosphate with p-tert-butylphenol, was demonstrated. The amount of p-tert-butylphenol necessary for transesterification of triphenyl phosphate to yield a mixture of phosphates of required composition was determined. If necessary, the composition of the phosphates can be adjusted by selective distillation of triphenyl phosphate in a vacuum. [ABSTRACT FROM AUTHOR]
