Abstract
The thermal decomposition of 6-hydroperoxy-6-hexanelactam was studied in the presence of antioxidants of the phenol, secondary aromatic amin e and piperidine-1-oxyl types. The thermolysis of the hydroperoxide pr oceeds mainly as a chain decomposition induced by radicals. This proce ss can be inhibited only by a piperidine-1-oxyl derivative. Phenols an d secondary aromatic amines only interrupt the chain reaction in the f irst step. Neither heterolysis, nor homolysis of the hydroperoxide is influenced by the presence of antioxidants.
