MICROPOROUS CRYSTALLINE ZEOLITIC MATERIAL (ZEOLITE ITQ-22), METHOD FOR PRODUCING AND APPLICATION AS CATALYST

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to the microporous crystalline material of zeolite origine (ITQ-22) which in tempered condition has the empiric formula x (M_1/nXO₂): y YO₂ - z GeO₂ : (1 - z) SiO₂ where M is H⁺ or at least one inorganic cation with +n charge; X is at least one chemical element with the oxidation rate +3 chosen preferably from the group that consists of Al, Ga, B, Fe and Cr; Y is at least one chemical element with the oxidation rate +4, different from Si and Ge, and chosen preferably from the group that consists of Ti, Sn and V; x has the value less than 0.2, preferably less than 0.1 and can be equal to zero, y has the value less than 0.1, preferably less than 0.05 and can be equal to zero, z has the value less than 0.8, preferably between 0.005 and 0.5 and can be equal to zero. In accordance with the invention, the material has the typically X-ray diffraction pattern.;EFFECT: invented material can recommended as catalyst in processes which include separation and transformation of organic compounds.;40 cl, 2 dwg, 18 ex
