Procedure
It has been found that ethionic acid can also be used to neutralize the sodium taurinate to yield taurine and sodium ethionate. After the separation of taurine, sodium ethionate is combined with equimolar ethionic acid and then treated with calcium oxide/calcium hydroxide to obtain sodium vinyl sulfate. In this variation of the cyclic process, sulfuric acid is eliminated from the process and production cost is further reduced.
