Abstract
A method for synthesizing an aluminosilicate molecular sieve of SWY framework topology via interzeolitic conversion is described. The method includes (1) a step of preparing a reaction mixture containing an aluminosilicate zeolite of FAU framework topology, a structure directing agent comprising a 1-methyl-1-[7-(trimethylammonio)heptyl]piperidinium cation, a source of an alkali metal cation, a source of hydroxide ions, and water; and (2) a step of heating the reaction mixture to obtain an aluminosilicate molecular sieve of SWY framework topology.
