Summary: | FIELD: organic synthesis catalysts. ^ SUBSTANCE: method of preparing catalyst based on high-silica zeolite comprises calcination of zeolite and treating it with ammonium salt solutions at 160-200°C followed by mixing with binder, drying, and calcination. High-silica zeolite utilized is ZSM-5 zeolite, which is treated with aqueous ammonium solutions until degree of Na+ cation substitution above 99% is attained. ^ EFFECT: increased catalytic activity and selectivity in benzene-ethylene alkylation process. ^ 1 tbl, 6 ex |
