The hydrolytical behavior of the substance was investigated with the
OECD guideline 111. The substance is hydrolytically unstable showing
half-life-times at 50°C of 30.39 h at pH 4, 44.08 h at pH 7 and 77.52 h
at pH 9. One transformation product was identified as tetrabromophthalic
The substance is hydrolytically unstable showing half-life-times at 50°C
of 30.39 h at pH 4, 44.08 h at pH 7 and 77.52 h at pH 9. One
transformation product was identified as tetrabromophthalic acid.
Using the van´t Hoff equation the half-life-times can be extrapolated to
a temperature of 20°C:
pH4: t1/2= 30.39h at 50°C is corresponding to t1/2= 10.1 days at 20°C
pH7: t1/2= 44.08h at 50°C is corresponding to t1/2= 14.7 days at 20°C
pH9: t1/2= 77.52h at 50°C is corresponding to t1/2= 25.8 days at 20°C
