Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to hydrogenation continuous flow equipment. Background Art

[0002] Hydrogenation reactions are very common in fine chemicals or pharmaceutical production. Typical reaction types include hydrogenation of unsaturated bonds and removal of certain protecting groups (also known as hydrogenolysis). In hydrogenation, high pressure can increase the solubility of hydrogen gas in the solvent when a catalyst is added. Heating can also play a similar role, thereby accelerating the reaction.

[0003] Catalysts play an important role in hydrogenation reactions. Most hydrogenations are completed under the catalysis of catalysts. Catalysts include transition metals, transition metal salts, and complexes formed by transition metals and ligands.

[0004] The existing hydrogenation continuous flow equipment has some shortcomings during use. During the feeding process, materials are easily accumulated, resulting in insufficient reaction and waste of raw materials. At the same time, the discharge port is easily blocked, affecting the reaction rate. For this reason, we propose a new type of hydrogenation continuous flow equipment. Utility Model Content
