MIPC was photocatalytically transformed to 3,4-dihydroxyl hypnone, 2-iso-butyl phenol and acetic acid, and mineralized ultimately in oxygenated TiO2 slurries. The photocatalytic degradation processed according to first order kinetics with the apparent rate constant depending on initial concentration, light intensity and the amount of catalyst. The amount of catalyst had an optimum value (0.5g/L). The apparent rate was inversely proportional to square root of the initial concentration approximately.
