| titleOfInvention | Synthesis method of 2-aminoethanesulfinic acid |
| abstract | The invention relates to the technical field of organic synthesis, in particular to a method for synthesizing 2-aminoethanesulfinic acid, which comprises the following steps: adding the reaction raw material A and the reaction raw material B into a solvent, heating for reaction, and performing post-treatment to obtain 2-aminoethanesulfinic acid; wherein, the reaction raw material A is dithionite, and the reaction raw material B is 2-halogen ethylamine or halogen acid salt thereof, or aminoethanol sulfate. Compared with the prior synthesis process, the synthesis method of 2-aminoethanesulfinic acid provided by the invention has the following technical advantages: the raw materials are cheap and easy to obtain, the process conditions are mild, the reaction is carried out under normal pressure, and the product can be directly separated out from the reaction system without refining, so that the product yield is high, and the overall production cost is low; therefore, the synthesis method of the 2-aminoethanesulfinic acid is very suitable for large-scale industrial production. |
