Abstract:
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.

Abstract:
The present invention provides a purification process whereby deferoxamine B produced by a microorganism and in mixture with other polyhydroxamates produced by the microorganism may be converted into its mesylate salt substantially free of the other polyhydroxamates and substantially free of chloride ion. The process includes adsorption and desorption of the deferoxamine B on an adsorption resin, direct precipitation of the deferoxamine free base out of the eluent from the adsorption resin, contacting of the deferoxamine B free base with methanesulfonic acid and isolation of the deferoxamine B mesylate salt by precipitation. This process minimizes decomposition of deferoxamine B.
