Modeling using the U.S.E.P.A's AOPWIN ver. 1.92 for photodegradation found that Half-life = 0.327 Days (12-hr day; 1.5E6 OH/cm³) Half-life = 3.929 Hours.Using HydroWin ver 1.67 (part of U.S.E.P.A. EPIWIN package) to estimate base/acid-catalysed hydrolysis at 25 deg C the results were:Kb Half-life at pH 8: 2.858 years, Kb Half-life at pH 7: 28.58 years and Total Kb for pH > 8 : 7.686E-003 L/mol-sec.
