FIELD: chemistry.
SUBSTANCE: H-form of ultrastable dealuminated Y-zeolites HUSY with SiO2/Al2O3 ratio within 5 to 120 is used as catalyst. As a rule, zeolites are combined with a binding agent represented by aluminum oxide, silicon oxide or their mix. Usually the catalyst is preliminarily activated by calcination in air at 300-600°C, while the method is implemented at 20-100°C. As a rule, cumol hydroperoxide concentration in the raw mix varies within 3 to 80%, and acetone, cumol, phenol or their mix with various component ratio are used as solvent.
EFFECT: increased process selectivity in relatively mild conditions.
