Title (EN) PROCESS FOR PRODUCING TAURINE FROM ALKALI TAURINATES
(FR) PROCÉDÉ DE PRODUCTION DE TAURINE À PARTIR DE TAURINATES ALCALINS
Abstract:
(EN) The present invention discloses a process and catalysts for producing taurine by catalytic ammonolysis of alkali ditaurinate, alkali tritaurinate, and their mixture. Useful catalysts are the ammonium and alkali salts of sulfate, bisulfate, sulfite, bisulfite, carbonate, bicarbonate, nitrate, phosphate, and organic carboxylic acids.
(FR) La présente invention concerne un procédé et des catalyseurs pour la production de taurine par une ammonolyse catalytique d'un ditaurinate alcalin, d'un tritaurinate alcalin, et de leur mélange. Les catalyseurs utiles sont les sels alcalins et d'ammonium de sulfate, de bisulfate, de sulfite, de bisulfite, de carbonate, de bicarbonate, de nitrate, de phosphate et d'acides carboxyliques organiques.
