| Abstract | Linear free energy relationships are given for use in estimating alkaline hydrolysis of carbamate pesticides in water as applied to environmental conditions. Plots of the second-order alkaline hydrolysis rate constants versus pKa of the resulting alcohol are given for N, N-dimethyl-, N-methyl-N-phenyl-, N-methyl-, and N-phenyl-carbamates. Use of these relationships allows one to estimate rate constants for specific compounds and make general statements about hydrolytic stability of classes of compounds. |
