실험 절차

In the first preferred embodiment of the present invention, ethionic acid is reacted with an aqueous solution of excess ammonia to afford ammonium ethionate. The molar ratio of ammonia to ethionic acid can be in the range of 5 to 15, more preferably in the range of 8 to 10. Too little ammonia increases the formation of ditaurine, a byproduct, while more ammonia is desirable for the reaction, too much ammonia increases the process cost in the recovery of excess ammonia. The reactions are described as follows:
