Abstract
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.
Claims9
A process for producing taurine from alkali ditaurinate, alkali tritaurinate, or their mixture, comprising,

- (b) subjecting the solution of (a) to ammonolysis reaction;
- (c) removing excess ammonia and neutralizing with an acid to obtain a crystalline suspension of taurine;
- and
- (d) recovering taurine by solid-liquid separation.
