Phototransformation in air

Half-life for reaction with photochemically-produced hydroxyl radicals: estimated to be between 0.175 and 0.262 days.

Half-life for reaction with photochemically-produced ozone: estimated to be 0.057 days.

Hydrolysis

Hydrolysis of a structural analogue of the substance, tetrahydromethylphthalic anhydride (MTHPA), has been investigated. The substancewas found to hydrolyse rapidly, resulting in formation of the respective di-acid. The calculated half-lives at 20 degree C are, for all three pH values ( 4, 7 and 9) below 3.5 minutes (about 0.06 hours).
