Abstract
Kinetic measurements by H-1 NMR spectroscopy and chemically induced dynamic nuclear polarization (CIDNP) effects were used to study thermolysis of sol utions of acetyl propionyl peroxide in methanol-d(4). It is found that the thermolysis may occur both by radical and by nonradical mechanisms. A schem e of the thermolysis is proposed. Parameters of the Arrhenius equation for the rate constants of the decomposition of the peroxide and the decarboxyla tion of acyloxyl radicals are obtained.
