EC number: 243-072-0
CAS number: 19438-60-9
Half-life for reaction with
photochemically-produced hydroxyl radicals: 30.1 hours.
Overall degradation rate constant with OH
radicals= 1.10E-6 cm3/(molecule-day)
In the presence of moisture,
hexahydro-4-methylphthalic anhydride is rapidly hydrolysed to
1,2-Cyclohexanedicarboxylic acid, 4-methyl-, that is most relevant to
various environmental compartments than the submission substance.
The stability of the substance in the
atmosphere was calculated using the software AOPWIN (v1.92). It is
predicted that the acid will be degraded in the atmosphere by reaction
with photochemically-produced hydroxyl radicals, with a half-life of
30.1 hours, and overall degradation rate constants with OH radicals of
