Abstract: The ESR method has been used for the measurement of the concentration-time dependence of the paramagnetic particles arising in the micropores of
the synthetic Na X faujasite after the adsorption of benzoyl peroxide from
benzene or methacrylic acid by heating the sample to the temperatures ranging
from 70°C to 100°C.
It has been found that the values of the rate constants k' corresponding to
the formation of stabilized radicals for the benzoyl peroxide adsorbed from
benzene at the temperatures between 80— 100°C are 1 x 10-3 —3 X 10-3 s-1
approximatively while the value of this constant for the benzoyl peroxide
adsorbed from methacrylic acid is к = 1.4 x 10-4 s-1 at 90°C.
The particles caught in the microstructure of zeolite are stable even at the
temperatures high above 100°C (140°C).
