Stability of the substance in the atmosphere was calculated using the computer program AOPWIN (v1.92). It is predicted that the substance will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated to be approximately 12 hours.
Hydrolysis as a function of pH has been examined using OECD test methods. While few details are available, it was reported that no hydrolysis occurred at pH 4 and 50 deg C. Measured half lives of 17.5 days at pH 7 and 11.9 days at pH 9 (extrapolated to 25 deg C from data obtained at elevated temperature) were reported.
A brief summary of a study conducted by Eastman Kodak describes no hydrolysis occurring following 96 hours in water at neutral pH and at 100 deg C.
Stability of the substance against hydrolysis was also calculated using SPARC online tool v4.6, module Hydrolysis.
A base-catalysed second-order hydrolysis rate constant (Kb) equal to 0.014 L/(mol-sec) at 25 deg Cwas estimated using a structure estimation method.This corresponds to half-lives of15.7 years at pH=7, 1.57 years at pH=8 and 57.3 days at pH 9.
