Phototransformation in air

The phototransformation in air of ‘Esterification products of 1,3-dioxo-2-benzofuran-5-carboxylic acid with nonan-1-ol’, calculated using the EPA model AOPWIN v1.92, is estimated in the following range values:

Overall OH radical rate constant: (33.53 ÷ 37.77) E-12 cm3/molecule-sec, equivalent to: (2.90 ÷ 3.26) E-6 cm3/molecule-day

OH Radical Reaction Half-Life: 10.20 ÷ 11.48 hours (24-hr day; 0.5E+06 OH/cm3)


Study technically not feasible. The substance is highly insoluble in water.
