Zeolites are utilized in many catalytic applications on large scale, and we report here the direct synthesis of alumino- and borosilicate versions of UZM-55, a recent unidimensional (1D) zeolite with a kinked channel containing both 10MR and 12MR. Up to approximately one heteroatom per unit cell has been incorporated, and the aluminosilicate forms tested for the MTH reaction. UZM-55 shows very high selectivity to propene at ∼51%, <5% selectivity to ethene, and high selectivity to C3 + C4 products of ∼76–79%. Unlike other 1D zeolites containing 12MR, UZM-55 clearly favors the olefin cycle mechanism.

了解一维含10MR和12MR的孔以及铝含量对MTH反应途径的影响：含杂原子的UZM-55的直接合成

沸石被广泛用于许多催化应用中，我们在此报告了UZM-55的铝硅酸盐和硼硅酸盐版本的直接合成，UZM-55是一种最近的一维（1D）沸石，具有扭结通道，同时包含10MR和12MR。每个晶胞中最多可掺入约一个杂原子，并且测试了铝硅酸盐形式的MTH反应。UZM-55对丙烯的选择性很高，约为51％，对乙烯的选择性<5％，对C3 + C4产品的选择性很高，约为76-79％。与其他含有12MR的1D沸石不同，UZM-55显然有利于烯烃循环机理。
