Application of ZL-N311 in the production of phenylethylamine hydrogenation to phenethylamine

The optical isomer of α-phenethylamine can be used as an alkaline splitter for the separation of acidic racemates. α-Phenethylamine is an important intermediate in the preparation of fine chemicals, and its derivatives are widely used in the field of pharmaceutical and chemical industry, mainly used in the synthesis of pharmaceuticals, dyes, fragrance emulsifiers, etc.

Determination of active hydrogen of ranny nickel by mannose method

There are many methods for the determination of the speech properties of Rainey nickel catalysts, and the determination of active hydrogen by mannose can meet the production requirements of most batch coping processes. The method is simple, accurate and fast.

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.

Reni Nickel Science Trivia (2)

Raney nickel is a solid-state heterogeneous catalyst composed of fine grains of nickel-aluminum alloy with a porous structure, which was first used as a catalyst by American engineer Murray Raney in the hydrogenation of vegetable oils. [1] 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 the name of Grace Chemicals (W. Rainey". R. Grace and Company), so strictly speaking, only products made by the company's Grace Davison division can be called "Lanny Nickel." The term "metal backbone catalyst" [2] or "sponge-metal catalyst" is used to refer to catalysts with a microporous structure and physical and chemical properties similar to Ranie nickel.

How to package Raney nickel

Raini nickel packaging, because it is a flammable and harmful substance, the packaging box is filled with vermiculite in the preparation of Raney nickel, the raw material nickel used is a carcinogen (group 2B, EU Class 3) and teratogens considered by the Internation Agency for Research on Cancer, and inhalation of fine alumina particles can cause bauxite pneumoconiosis, so the preparation of Raini nickel must be careful. In the activation process, because its surface area is gradually increasing and the hydrogen produced by the leaching reaction is constantly adsorbed, the activated Raini nickel has medium flammability, so the reaction in which Raini nickel participates should be treated in an inert gas environment.

Amorphous alloy catalytic hydrogenation method to prepare indole-2-carboxylic acid

Using o-nitrotoluene and diethyl oxalate as starting materials, the ethanol alkaline solution of ethyl o-nitrophenylpyruvate was synthesized, and then the indole-2-carboxylic acid was synthesized by catalytic hydrogenation at 60~70 °C and 1.5MPa pressure with a total yield of > 70% (calculated by o-nitrotoluene), and the compound was identified by melting point, NMR, GC-MS spectra. The synthesis of indole-2-carboxylic acid by amorphous catalytic hydrogenation method has low cost, good activity, simple post-treatment and no environmental pollution.
