SYNTHESIS AND USE OF ZEOLITIC MATERIAL HAVING THE ITH FRAMEWORK STRUCTURE TYPE

摘要

A zeolitic material having the ITH framework structure type.A process for the preparation of a zeolitic material having the ITH framework structure type, the process comprising : (1) preparing a mixture comprising one or more specific organotemplates as structure direct-ing agents, one or more sources of YO2, optionally one or more sources of X2O3, seed crystals, and a solvent system, wherein Y is tetravalent element and X is a trivalent ele-ment,(2) heating the mixture obtained in (1) for crystallizing a zeolitic material having the ITH framework structure type comprising YO2 and optionally X2O3 in its framework structure; wherein the one or more organotemplates comprise a specific polymeric cation.
