Okubo, Teiji published the artcileRadiolysis of sulfuric acid esters in dilute aqueous solution by Co60 γ-radiation, Recommanded Product: Potassium 4-nitrophenyl sulfate, the publication is Repts. Liberal Arts Sci. Fac. Shizuoka Univ., Nat. Sci. (1959), 203-7, database is CAplus.
K salts of several sulfuric acid esters (0.1 M) were irradiated at pH 5.8. After 18,000 r. γ-radiation the acid formed was determined from the pH change. Esters irradiated, acid yield in micromoles/10 ml., and G-value are as follows: Me, 0.42, 2.7; Et, 0.32, 2.1; Pr, 0.06, 0.4; iso-Pr, 0.12, 0.8; Bu, 0.07, 0.5; amyl, 0.08, 0.5; cyclohexyl, 0.04, 0.3; benzyl, 0.69, 4.4; Ph, 0.67, 4.3; p-tolyl, 0.71, 4.6; p-nitrophenyl, 0.69, 4.4. The acid yield was proportional to dose from 5000 r. to 30,000 r. No effect of the dose rate at 15-60 r./min. was observed. The acid yield of K ethyl sulfate increased linearly with ester concentration to 0.1M and was then constant to 0.4M. KMeSO4 or KEtSO4 (0.1M) may be used as a chem. dosimeter for measuring x- or γ-radiation in the dose range 5000-50,000 r.
