摘要: Catalytic behavior of isomorphously substituted B‐, Al‐, Ga‐, and Fe‐containing extra‐large pore UTL zeolites was investigated in Knoevenagel condensation involving aldehydes, Pechmann 1‐naphthol with ethylacetoacetate, Prins reaction β‐pinene formaldehyde compared large‐pore aluminosilicate zeolite BEA representative Metal‐Organic‐Frameworks Cu3(BTC)2 Fe(BTC). The yield the target product over catalysts increases following sequence: (Al)BEA < (Al)UTL (Ga)UTL (Fe)UTL Fe(BTC) (B)UTL being mainly related to improving selectivity decreasing strength active sites individual catalysts. catalytic performance Fe(BTC), containing highest concentration Lewis acid appropriate is superior Fe‐substituted ethylacetoacetate.
