Abstract
The decomposition of endrin in hexane solutions under the sun light were investigated. A main photolysis product (III) was found out by means of the thin-layer chromatography and the electron capture gas chromatography. It was cleared that this substance was the same as one of the spots which were yielded by ultraviolet irradiation of endrin in hexane solution. The photolysis product was isolated, using silicagel column, and its chemical structure was elucidated by infrared spectrophotometry, nuclear magnetic resonance and mass-spectrometry. Also, in this study, 1, 8-exo-9, 10, 11, 11-hexachloropentacyclo [6, 2, 1, 13, 6, 02, 7, 04, 10] dodecan-5-one (II) was synthesized and it was assumed that a photolysis product (III) may be formed through the compound (II) under the sun light.
