ALKYLATION OF AROMATIC MOLECULES USING A SILICA- ALUMINA CATALYST DERIVED FROM ZEOLITE

摘要

Aromatic molecules are alkylated using a silica-alumina catalyst derived from zeolite. The silica-alumina catalyst is a partially collapsed zeolite, i.e., a material of reduced crystallinity. The alkylation process which employes this material of reduced crystallinity is characterized by a high level of selectivity for the production of monoalkylated product.
