Kinetics and Hydrolysis Mechanism of 2,4-dichlorofenoxyacetic acid
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 1
Abstract
The hydrolytic transformation kinetics of the 2,4-dichlorofenoxyacetic acid (2,4-D) was investigated as a function of pH. The hydrolysis rate was pH-dependent and the first order. The hydrolysis was much faster in acidic media than under neutral conditions. Two metabolites have been isolated and identified. At all pH values studied, the primary pathway of degradation was the cleavage of the methoxyl oxygen bond.
