Problems solved by technology
At present, the industrial production of hydrogen mainly adopts methods such as the water gas method, the method of electrolysis of water, and the method of electrolysis of saturated saline. The hydrogen prepared by the above methods will inevitably contain impurities such as water vapor. During the hydrogenation reaction, it will affect the entire reaction system, and there will be reaction errors, which will affect the quality of etiforine hydrochloride produced

Description
technical field [0001] The invention relates to a pharmaceutical production technology, in particular to a hydrogen purification device for etiforine hydrochloride production. Background technique [0002] Etiforine hydrochloride is a pharmaceutical raw material intermediate with a wide range of applications. Its function is to strengthen myocardial contractility, constrict blood vessels, and increase blood pressure. It is mainly used for medical emergency treatment of hypotension. Etiforine hydrochloride is currently mainly prepared by amination of α-bromo-m-hydroxyacetophenone to obtain α-benzylethylamino-m-hydroxyacetophenone hydrochloride, and then through catalytic hydrogenation to obtain Etiforine hydrochloride Forest. Therefore, in the production of etiformine hydrochloride, hydrogen plays an important role as the main raw material of the catalytic hydrogenation reaction, and its purity and impurity components have a great influence on the catalytic hydrogenation rea...
