The framework structures of two closely related molecular sieves, SSZ-26 and SSZ-33, are described. These materials possess a previously missing but desired structural feature in a group of industrially significant zeolites. They contain a three-dimensional pore system that provides access to the crystal interior through both 10- and 12-rings. This property is a consequence of the organic structure-directing agents used in the synthesis of these materials. These materials are examples of the purposeful design of a micropore architecture. Both SSZ-26 and SSZ-33 contain the 4=4-1 building unit that had been previously found only in natural zeolites.
描述了两种密切相关的分子筛SSZ - 26和SSZ - 33的骨架结构。这些材料在一组具有工业重要性的沸石中具有以前缺失但理想的结构特征。它们包含一个三维孔系统，该系统通过10元环和12元环都能通向晶体内部。这种性质是合成这些材料时所用有机结构导向剂的结果。这些材料是微孔结构有目的设计的实例。SSZ - 26和SSZ - 33都包含4 = 4 - 1结构单元，该结构单元以前仅在天然沸石中发现过。
