Framework-Bound Organic Structure-Directing Agent-Containing Molecular Sieves and Their Manufacturing Process

摘要

The present invention is based on the framework-bound Organic Structure-Directing Agent-Containing Molecular Structure which is an organic-inorganic hybrid molecular sieve completely different from the conventional zeolite and aluminophosphate-based molecular sieves And more particularly to ECR-40 seeds (Seed) as well as organic structure-directing molecules including hydroxyl groups (OH Group) (Al) in the skeleton structure and the organic structure-derived molecules directly form covalent bonds, together with various ECR-40 silicoaluminophosphate organic / inorganic mixed molecular sieves (Si ) Instead of germanium (Ge) by homologous substitution, and FOMS including the PST-10 germanoaluminophosphate organic-inorganic mixed molecular sieves There is provided a method for this purpose.In order to accomplish the above object, the present invention is characterized in that each basic skeletal structure is composed of oxides having the same molar ratios as the following formulas (1) and (2), and has uniform pores having a minimum size of 3 therein The organic structure-derived molecules used in the synthesis have a strong covalent bond with the molecular sieve inorganic skeleton, and thus can be used as a separating agent, adsorbent for a specific molecule, a catalyst having a unique shape selectivity, or a novel crystalline organic-Can be achieved by providing its own FOMS, ECR-40 and PST-10 molecular sieves.1.0 R: 1.0-2.0 Al₂O₃: 0.5-1.0 P₂O₅: 0.5-1.0 SiO₂(One)1.0 R: 1.0-2.0 Al₂O₃: 0.5-1.0 P₂O₅: 0.5-1.0 GeO₂(2)Here, R represents an organic structure-derived molecule having a covalent bond with the molecular sieve inorganic skeleton.
