| titleOfInvention | A kind of catalyst and its preparation method and its application in the preparation of pyridine compounds by condensation of aldehyde and ammonia |
| abstract | The invention provides a catalyst, its preparation method and its application in the preparation of pyridine compounds by condensation of aldehydes and ammonia, which belongs to the technical field of fine chemical intermediate production. %-2.5% of modified metal oxide, 0.5%-2.0% of P 2 O 5 by mass fraction, and the rest are alumina and kaolin. The ITH configuration molecular sieve is a hydrogen-type silicon-aluminum ITQ‑13 molecular sieve, and the silicon-aluminum molar ratio ranges from 40 to 120. The catalyst raw material is mixed with water spray molding and calcined to obtain a finished catalyst. The catalyst is used in the production of pyridine compounds prepared by condensation of aldehyde and ammonia. The catalyst of the invention has the advantages of simple preparation process, good repeatability, easy industrial scale-up, and is used in the process of preparing pyridine compounds by condensing aldehydes and ammonia, and has the characteristics of high pyridine selectivity and low by-products. |
