반응 단계
If calcium carbonate is used as a source of calcium, the sequence of addition needs to be altered. After ethionic acid is diluted with water and hydrolyzed into isethionic acid and sulfuric acid, calcium carbonate is carefully added the aqueous solution to form a slurry of calcium sulfate and calcium isethionate. Then calculated or excess amount of alkali metal sulfate is introduced into the reaction system to replace calcium in calcium isethionate with alkali metal in alkali metal sulfate.
