Study on liquid phase hydrogenation reaction catalyzed by ZL-N411 amorphous alloy

The hydrogenation reaction of dicyclopentadiene (DCPD) was investigated by ZL-N411 amorphous alloy catalyst, and the effects of stirring speed, temperature, pressure and catalyst concentration on the hydrogenation reaction of dicyclopentadiene were studied. The results showed that the DCPD hydrogenation reaction was a series reaction, and the intermediate products were mainly 9,10-dihydrodicyclopentadiene (9,10-DHDCPD) and a small amount of l,2. dihydrodicyclopentadiene (1,2-DHDCPD). DCPD is easy to hydrogenate to form the intermediate product 9,10-DHDCPD, which is further hydrogenated to tetrahydrodicyclopentadiene (endo-THDCPD) requires more severe conditions. The DCPD hydrogenation process adopts two stages, the temperature is llO °C, the second stage is 130 °C, the pressure is 1.5MPa, and the catalyst concentration is 1.18%. The hydrogenation activity of amorphous alloy (catalyst) on DCPD is significantly higher than that of RaneyNi, and the hydrogenation reaction of l, 2 positions can be carried out to generate 1,2-DHDCPD, and the amount of catalyst is small, the reaction temperature and reaction pressure are low, the reaction time is short, and the by-products are few.

Reni nickel catalyst science knowledge(1)

Physical and chemical properties: Reni nickel catalyst before activation is silver-gray amorphous powder (nickel-aluminum alloy powder), with a moderate degree of flammability, partial activation in the presence of water and the production of hydrogen easy agglomeration, long-term exposure to air is easy to weather. Nickel-aluminum alloy powder is activated into gray-black particles, accompanied by active hydrogen, extremely unstable, oxidative combustion in the air, must be immersed in water or ethanol for preservation. It was first used by American engineer Murray Rainey as a catalyst in the hydrogenation of vegetable oils. The preparation process is to treat nickel-aluminum alloy with concentrated sodium hydroxide solution, in this process, most of the aluminum will react with sodium hydroxide and dissolve, leaving a lot of micropores of different sizes. In this way, the surface of Raininickel is a fine gray powder, but from a microscopic point of view, each tiny particle in the powder is a three-dimensional porous structure, this porous structure greatly increases its surface area, and the large surface area brings high catalytic activity, which makes Raininickel widely used as a heterogeneous catalyst in organic synthesis and industrial hydrogenation reactions. Since "Rainey" is a registered trademark of Grace Chemicals, strictly speaking, only products manufactured by the company's Davidson Chemical Division can be called "Lanny Nickel". The term "metal backbone catalyst" or "sponge-metal catalyst" is used to refer to catalysts with a microporous structure and physical and chemical properties similar to Raney nickel.
