<正>Pirimicarb(2-(dimethylamino)-5,6-dimethylpyrimidin-4-yl-N-dimethylcarbamate)is one of the class of substituted N-dimethylcarbamate insecticides.A primary pathway for the transformation of pirimicarb in aquatic environments is hydrolysis.In this paper,we focus on hydrolysis of pirimicarb affected by pH and temperature.
