При этом образуетс кремнефторид аммони и 100% сернистый ангидрид, которые вл ютс товарными продуктами ..The resulting sulphite solution is treated with a solution of fluorosilicic acid (waste of superphosphate production) under conditions of excess acid or with slight heating. This forms ammonium silicofluoride and 100% sulfurous anhydride, which are marketable products.
