TITANIUM-CONTAINING ZEOLITE, METHOD OF PREPARATION THEREOF (VERSIONS), METHOD OF EPOXIDATION OF OLEFINS, AND BENZYL- SUBSTITUTED AMMONIUM DERIVATIVES

摘要

FIELD: molecular sieves. SUBSTANCE: molecular sieve has matrix structure isomorphous to beta-zeolite structure, contains silicon and titanium but no lattice aluminium. This zeolite may efficiently catalyze epoxidation of olefins when using hydrogen peroxide or organic hydroperoxide as oxidizing agent. EFFECT: new high-efficiency catalyst proposed.
