Abstract: The kinetics of photosensitized oxygenation of cis, cis-1,5-cyclooctadiene was studied in the presence of different sensitizers. (Rose bengal, Hematoporphyrin, Methylene blue, Hypo-crellin A) matching high pressure sodium lamp. According to the rates of consumption of cis, cis-1, 5-cyclooctadiene, the order of photosensitized oxygenation efficiency is as follows:Hypocrellin A > Methylene blue > Hematoporphyrin > Rose bengal

Key words: Singlet Oxygen, Hypocrellin A, High Pressure Sodium Lamp, Photosensitized Oxygenation Efficiency
