【Abstract】 The chemical hydrolysis of sulfonylurea herbicide is firstorder kinetic nuclearphylic substitution reaction, it conforms Arrhenius formula. The acid is effective catalysis of this reaction. The major hydrolysis products are arylsufonamide and aminoheterocyclic compounds. The mechanism and the rate of chemical hydrolysis are related to the structure of compound itself and the characters of reaction medium and environmental factors such as temperature and acidity, etc.更多还原
