From the read across with 1,3 (or 1,4)-bis[1-(tert-butylperoxy)-1-methylethyl]benzene, extrapolated values at 25°C (using the Arrhenius equation): pH 4 : half-life = 56.4 dpH 7: half-life = 74.7 dpH 9: half-life = 96.5 d
There is no data on
1,4-bis[1-(tert-butylperoxy)-1-methylethyl]benzene. A read across
approach is proposed with 1,3 (or
was evaluated in a study performed in accordance with OECD testing
guideline 111 and EPA OPPTS 835.2110 under GLP requirements.
The results from the hydrolysis test
indicate that 64.6, 71.4 and 77.3% of the reaction were observed after 5
days at pH 4, 7 and 9 solutions respectively, at 50 °C. The test has
demonstrated that the substance is hydrolytically stable at pH 2.6 after
24 hours. The degradation rates were calculated using first order
kinetics as follows:
pH 4 : half-life = 7.9 d
pH 7: half-life = 10.3 d
pH 9: half-life = 13.4 d
Extrapolated values at 25°C, using the
pH 4 : half-life = 56.4 d
pH 7: half-life = 74.7 d
pH 9: half-life = 96.5 d
