INDIRECT PHOTOLYSIS due to 1O2 (singlet dioxygen)
- Rate constant: 1.1 E7 M-1 s-1 at pH 8.3
2.4 E7 M-1 s-1 at pH 8.8
1.6 E8 M-1 s-1 at pH 10
3.5 E8 M-1 s-1 at pH 11.5
- Half life t1/2: 500 h under noon summer sunlight(Switzerland) with 4E-14 M singlet oxygen
In the hydrosphere the cresols are expected to undergo photolytical
degradation because of the presence of the aromatic ring which acts as a
chromophore. By irradiation of solutions of p-cresol in a merry-go-round
reactor, with rose bengal as a sensitizer, a half-life of 21 d in
surface water under noon summer sunlight and the latitude of Switzerland
In the hydrosphere a half-life of 21 d in surface water under noon summer sunlight and the latitude of Switzerland was estimated for p-cresol.
