Abstract
A process is described for forming taurine, which comprises reacting monoethanolamine with sulfuric acid to provide an 2-aminoethanol hydrogen sulfate ester product, combining the 2-aminoethanol hydrogen sulfate ester product with at least one of carbon dioxide, a carbonate or bicarbonate and with at least one of a sulfite or bisulfite to form a sulfonation reaction mixture, and heating the sulfonation reaction mixture for a sufficient time to form a taurine product therefrom. The efficiency of the sulfonation step is improved sufficiently to enable a continuous process for making taurine, particularly with at least some concurrent water removal in the first, esterification step to facilitate full conversion of the monoethanolamine to the desired 2-aminoethanol hydrogen sulfate ester intermediate.
