There is disclosed a process for producing taurine by decomposing ammonium taurinate to taurine and ammonia. Ammonium taurinate is prepared by the hydrogenation of ammonium 2-nitroethanesulfonate, by the reaction of aziridine with ammonium bisulfite, or by mixing alkali taurinate with an ammonium salt selected from the group from ammonium isethionate, ammonium bisulfite, ammonium sulfite, ammonium sulfate, ammonium bisulfate, ammonium chloride, ammonium bromide, ammonium nitrate, ammonium phosphate, ammonium hydrogen phosphate, ammonium dihydrogen phosphate, ammonium carbonate, ammonium bicarbonate, ammonium carboxylate, ammonium alkyl sulfonate, ammonium aryl sulfonate, and a mixture of two or more thereof. |
