摘要：
Recent procedures for synthesis of zeolite Y in either cubic or hexagonal forms that make use of crown ethers as template, are modified using gels containing fluorides. 15 Crown-5 ether gives the cubic and 18 crown-6 ether gives the hexagonal form. By using a synthesis mixture in which both templates are present, intergrowths of the two forms can be produced including material analogous to ZSM-20 that is typically synthesized in alkaline systems.
