The half-life times of styrene oxide in aqueous solution are 18 h (pH 7) and 1.6 days (pH 9) at 25 °C, respectively.
as a function of pH was performed according to OECD Guideline 111 and
EU-method C.7. At temperatures from 20 to 60 °C a temperature depending
decrease of half-life time was observed; 27 h to 1.2 h at pH 7 and 2.4 d
to 2.4 h at pH 9. Based on the results, half-life times of 18 h (pH 7)
and 1.6 days (pH 9) were deduced for styrene oxide from the reaction
rate constants at 25 °C.
