| titleOfInvention | A kind of preparation method of taurine |
| abstract | The invention discloses a preparation method of taurine, which comprises: (1) in the presence of an ammonia complex ion catalyst, an aqueous solution of sodium isethionate and ammonia are subjected to ammonolysis reaction to obtain a reaction solution containing sodium taurine (2) the reaction solution containing sodium taurine undergoes deamination, concentration and water removal, acidification and crystallization to obtain the taurine and the mother liquor; the ammonia complex ion catalyst is obtained by the complexation of ammonia and catalyst precursor, The catalyst precursor contains one or more metal elements among chromium, zinc, nickel, cobalt, copper and silver. The method has the advantages of mild process conditions, short reaction time, high yield, simple source of catalyst and the like. |
