Description

technical field [0001] The invention belongs to the field of chemical production, and in particular relates to an improved recovery device for producing 3-amino-1-adamantanol. Background technique [0002] Since the beginning of the 21st century, the latest diabetes treatment drug dipeptidyl peptidase (DPP-IV) inhibitor has gradually emerged, breaking the monopoly of insulin, sulfonylureas, biguanides and other drugs. Most of these drugs use 3-aminoadamantanol or its derivatives as intermediates. However, the patents of the original research are close to expiration, and there are many applications for imitation one after another. The demand for 3-amino-1-adamantanol as a key raw material is very large. [0003] In the production of 3-amino-1-adamantanol in the prior art, first add concentrated sulfuric acid to the reaction liquid storage tank, and at the same time slowly add amantadine hydrochloride, and pass in frozen water to keep the temperature below 20°C, stir evenly, ...
