Model calculation using EpiSuite 4.0 (AOP program v1.92, US-EPA, 2013):Half-life for reaction with hydroxyl radicals ( 1.5E6 OH/cm³) = 20.6 hHalf-life for reaction with ozone (at 7E11 mol/cm³) = 24.2 h
does not possess UV-absorbing structures. Therefore, direct photolysis
is not expected to occur to any significant degree.
experimental data with model atmospheres exist for MMA which are broadly
consistent with model data, no experimental photodegradation data exist
for MAA. A
model calculation using EpiWin v4.00 AOP v1.92 showed a rate constant
for the reaction of MAA with hydroxyl radicals in the atmosphere of 18.6460
From this rate constant the half-life for the reaction of OH radicals
with the test substance is calculated as 20.6 h.
after evaporation or emission to air, methacrylic acid will be rapidly
degraded by photochemical processes.
