    Abstract

    The synthesis of Fe-MCM-22 zeolite is reported for the first time. Its structure and characteristics are similar to those of the MCM-22 zeolite. The aluminum is in a framework tetrahedral position in the [Fe,Al]-MCM-22 samples. The white color of the samples, the increase of the 29Si and 27Al NMR linewidths with increasing Fe content and the constancy of the (Fe+Al)/u.c. values all suggest that Fe is also incorporated in tetrahedral position of the framework.
