Conclusions
-
1.
The kinetics of the hydrolysis of cyclic oligomers of polycaproamide was investigated in a broad range of temperatures and H2SO4 concentrations by a spectrophotometric method.
-
2.
The effective rate constant of hydrolysis passes through a maximum with increasing acid concentration.
-
3.
A mechanism of hydrolysis was proposed.
-
4.
The anomalous reactivity of the cyclic dimer of polycaproamide is explained by electrostatic interaction of closely situated amide groups through space.
