Cyclic process for producing taurine from monoethanolamine |
| abstract |
There is disclosed a cyclic process for producing taurine from monoethanolamine comprising the steps of: (a) recovering monoethanolamine sulfate from an aqueous mother liquor solution; (b) reacting the monoethanolamine sulfate with sulfuric acid to form an aqueous solution comprised of monoethanolamine bisulfate; (c) heating the aqueous solution comprised of the monoethanolamine sulfate and optionally added monoethanolamine sulfate to yield 2-aminoethyl hydrogen sulfate ester; (d) reacting the ester with ammonium sulfite or an alkali sulfite to yield taurine and ammonium or alkali sulfate; (e) separating taurine and ammonium or alkali sulfate to give an aqueous mother liquor solution; and (f) recovering the monoethanolamine sulfate from the aqueous mother liquor solution and recycling to the monoethanolamine sulfate to step (b). |
