摘要
Photolysis of isoprothiolane (di-isopropyl 1,3-dithiolan-2-ylidenemalonate) was studied as a thin film on glass surface, soil surface, and plant surface. Three photoproducts, namely 1,3-dithiolan-2-ylidenepropane, 1,3-dithiolan-2-ylidenemalonic acid, and 1,3-dithiolan-2-ylidenemethane have been identified on the basis of GC-MS method. The major route of photodegradation of this compound is through the de-esterification process, followed by de-carboxylation and rearrangement. The rate of photodegradation in all cases followed first-order kinetics with a statistically significant correlation coefficient.
