Description

technical field

[0001] The invention relates to the technical field of taurine preparation, in particular to an ammonolysis reaction system, a preparation method of taurine intermediate sodium taurate and a preparation method of taurine. Background technique

[0002] Taurine (2-aminoethanesulfonic acid), also known as taurocholic acid and taurobilin, is white crystal or powder, odorless, non-toxic, and slightly sour. It is a non-protein amino acid, one of the important amino acids necessary for the human body, and has unique pharmacological and nutritional health effects. Taurine can be widely used in medicine, food additives, optical brighteners, organic synthesis and other fields, and can also be used as biochemical reagents, wetting agents, buffers, etc. Western developed countries have generally used taurine in medicine and food additives.

[0003] The preparation methods of taurine mainly include biological extraction method, fermentation method and chemical synthesis...
