Description of key information
7ppd was found to be hydrolytically instable at pH 4, pH 7 and pH 9.
Additional information
Hydrolysis
7PPD was found to be hydrolytically instable at pH 4, pH 7 and pH 9.
The follwoing dissappearance time (DT50) and half-life time was estimated:
DT50 (20 °C, pH 4): approx. 370 h
DT50 (20 °C, pH 4): approx. 15 h
t(1/2) (20 °C, pH 7): 7 h
t(1/2) (50 °C, pH 7): 1 h
DT50 (20 °C, pH 9): approx. 10 h
DT50 (20 °C, pH 9): approx. 1 h
The following degradation products were detected:
pH 4: aniline, p-benzoquinone, p-hydroquinone
pH 7: aniline, p-benzoquinone, unknown component
pH 9: aniline, unknown component
Photolysis
7PPD degrades rapidly by indirect photolysis and by hydrolysis.
