| 摘要 |
The present invention discloses a cyclic process for the production of taurine from ethylene oxide in a high yield of greater than 95% by continuously converting the byproducts of the ammonolysis reaction, sodium ditaurinate and sodium tritaurinate, to sodium taurinate. The cyclic process is completed by using sulfur dioxide or sulfurous acid to neutralize sodium taurinates to recover taurine and to regenerate sodium bisulfite, which is then reacted with ethylene oxide. |
