Abstract

The invention provides a method for preparing taurine from sodium isethionate, which uses molybdate homogeneous catalyst to catalyze the ammonolysis reaction of sodium isethionate, and then obtains the finished taurine through steps such as neutralization and crystallization separation. sulfonic acid. Compared with traditional basic catalysts, the process can significantly reduce the temperature and pressure of the ammonolysis reaction of sodium isethionate, shorten the reaction time, and is easy for industrial production.

Description

technical field

[0001] The invention relates to a method for preparing taurine from sodium isethionate. Background technique

[0002] Taurine, also known as taurocholic acid, taurobilin, and chemical name 2-aminoethanesulfonic acid, is an essential non-protein amino acid that exists in almost all organs of humans and mammals in free form. The role of taurine is different from that of other amino acids. It can promote the growth and development of the nervous system, protect the brain, improve memory, and improve optic nerve conduction and visual function. It can also protect the heart, prevent and treat cardiovascular and cerebrovascular diseases and other important diseases. Function. Taurine has high medicinal value and is an important nutrient. It is widely used in functional beverages, pet food, health food, feed, medicine and other fields. It can also be used as biochemical reagents and other organic synthesis intermediates. A fine chemical with wide application value...
