Description of key information
Additional information
The photodegradation of cumene hydroperoxide in air by reaction with OH radicals was calculated using EPIWIN v3.20, AOPWIN v1.92. Based on the reaction rate constant k(OH)=8.63 x 10E-12 cm³/molecule x sec (25°C) and assuming a OH radical concentration of 5 x 10E5 radicals/cm³ (24 h d) a half-life t1/2=44.6 h was calculated.
The hydrolysis as a function of pH of 1-methyl 1-phenylethyl hydroperoxidewas assessed according to the OECD guideline 111. According to the results of this study,1-methyl 1-phenylethyl hydroperoxidecan be considered as stable at pH 4, 7 and 9.
At pH 1.2, the test item is hydrolytically unstable. The half-lives were respectively 14.1, 53.3, 311(estimation) and 1386 hours for the temperatures 50, 37, 25 and 15°C.
