Sulfate-hydrogensulfate hydrolysis

Sulfate-Hydrogensulfate Hydrolysis If sulfuric acid is used as the cation resin regenerant, under insitu regeneration a portion of anion... [Pg.220]

The complete hydrolysis of the soluble cellulose derivative required gradual addition of water and, preferably, acid. Water can act on cellulose acetate hydrogensulfate in three ways (a) saponification of sulfate groups, (b) saponification of acetate groups, and (c) hydrolysis of glycosidic bonds. Reaction (a) is most rapid and occurs under the mildest conditions. As Table II shows, the product is not any more water soluble (Entries 1-4). Under more severe conditions, the deacetylation (b) has proceeded to water-soluble products, the total amount of dissolved carbohydrates corresponding to theory (Entries 5-10). How-... [Pg.163]

After remix, and during the rinse, the prevailing neutral pH condition leads to hydrolysis of the hydrogensulfate ion which reverts to sulfate and releases sulfate ions as sulfuric acid ... [Pg.221]
