摘要

The dependence of the air-release time on the composition of flame‑retardant oil derived from mixed phosphate esters made using phenol and 4‑tert‑butylphenol (tert‑butylated oil) was studied. The air-release time is a function of the ratio of the major components, namely, (tert‑butylphenyl) diphenyl phosphate (II) and di(tert‑butylphenyl) phenyl phosphate (III), and rises sharply with an increasing content of tri(tert‑butylphenyl) phosphate (IV); triphenyl phosphate (I) has only a minimal effect. Esters II‑IV were isolated as pure compounds and characterized. The oil components, which are solids at room temperature, can form mixtures with pour point at –17°C and below. An empirical model was proposed for quantitatively describing the air-release time on the composition selected for tert‑butylated oils with physicochemical characteristics suitable for use in industry as fire‑resistant oils.
