Embodiment 1

[0024] The catalyst of embodiment 1 is 15%Ni-0.1%Ru / Al 2 o 3 . Weigh 20 grams of Al 2 o 3 (20-40 mesh), roasted at 500°C for 6 hours before use, and configure 22ml containing 10.999 grams of Ni(NO 3 ) 2 and 0.041 g RuCl 3 aqueous solution, with half of this aqueous solution impregnated with the above Al 2 o 3 The carrier is air-dried, oven-dried at 120°C for 4 hours (h), and baked at 500°C for 5 hours. The other half of the above aqueous solution was impregnated with the above Ni, and Ru metal-loaded Al 2 o 3 The carrier is then air-dried, oven-dried at 120°C for 4 hours, and baked at 500°C for 5 hours. Before use, in 300°C hydrogen (atmospheric pressure, 2500h -1 ) reduction activation for 5 hours.

Embodiment 2

[0026] Catalyst 15%Ni-0.3%Pd-0.03%Ru / Al of embodiment 2 2 o 3 . In addition to the configuration of 22ml containing 11.157 grams of Ni (NO 3 ) 2 , 0.119 g PdCl 2 and 0.0147 g RuCl 3 Except aqueous solution, all the other preparation steps are identical with embodiment 1.

Abstract

The invention discloses a catalyst for use in the preparation of piperidine and piperidine derivatives by hydrogenation of pyridine and pyridine derivatives. The catalyst consists of an active component, an assistant, and a carrier. The active component is one or several of transitional metals Pd, Rh and Ni. The carrier is one of Al2O3, active carbon, ZrO2 or SiO2. In fixed fluidized bed reactor, the pyridine and pyridine derivatives can be converted into the piperidine and piperidine derivative products with high activity and high selectivity at certain temperature and hydrogen pressure and under the action of the catalyst.

Description

technical field [0001] The present invention relates to a kind of catalyst of pyridine and pyridine derivative hydrogenation to prepare piperidine and piperidine derivative, relate to a kind of catalyst that is used for pyridine and pyridine derivative (such as monoalkyl or polyalkylpyridine) hydrogenation conversion in detail Catalysts for piperidine and piperidine derivatives such as mono- or polyalkyl piperidines. technical background [0002] Piperidine, also known as hexahydropyridine or azacyclohexane, is a colorless liquid. Has a peppery smell. Density 0.8606. Melting point -7~-9℃. The boiling point is 106°C. Soluble in water, ethanol and ether. A strong organic base that reacts with inorganic acids to form salts. Can be volatile together with steam. Piperidine is mainly used in organic synthesis, pharmaceuticals, solvents, epoxy resin curing agents, chemical reagents, rubber vulcanizing agents, etc. The main preparation method is the hydrogenation of pyridine...
