Preparation of isethionic acid |
| abstract |
A method for the preparation of isethionic acid by treating an alkali metal isethionate with hydrochloric acid to form isethionic acid and a chloride salt. The chloride salt is removed so as to provide at least a 50% by weight aqueous solution of the isethionic acid after removal of excess hydrochloric acid, which solution may be further reacted with a polyvalent metal oxide, hydroxide or amine to form the corresponding heavy metal isethionate. Zinc isethionate, for instance, is useful as a catalyst for making acyl isethionates used in making soap bars. |
