Description

technical field

[0001] The invention relates to a process for preparing taurine by ion membrane method. Background technique

[0002] Taurine is a sulfur-containing non-protein amino acid with the chemical name 2-aminoethanesulfonic acid (NH 2 CH 2 CH 2 SO 3 h). In recent years, with the in-depth research on the physiological effects and nutritional value of taurine, its application has become more and more widespread, and it has important applications in medicine, food, dyes, surfactants, pH buffers, etc. As a drug, taurine can be used for choleretic, liver protection, detoxification, anti-inflammatory, antipyretic, sedative, anticonvulsant, antiarrhythmia, treatment of cardiac insufficiency, regulation of osmotic pressure, lowering blood pressure, treatment of arteriosclerosis, inhibition of central nervous system, maintenance of eyesight etc. At present, some developed countries in the world, such as the United States and Japan, have added appropriate amounts of tau...
