A method is disclosed for the production of taurine by a cyclic process of reacting ethylene oxide with sodium bisulfite and ammonium to obtain sodium taurinate. After excess ammonia is removed from the reaction mixture, sodium taurinate is neutralized with sulfur dioxide or sulfurous acid to recover taurine and to regenerate sodium bisulfate, which is then reacted with ethylene oxide. |
