Process for improving the storage stability of alkali persalts |
摘要 |
A process for improving the storage behavior of alkali persalts in particularly alkali percarbonates, by preparing a granulate composition therefore is disclosed. The process comprises the steps of: (a) granulating an alkali persalt, wherein the alkali cation is an alkali metal cation or ammonium and which is selected from the group consisting of solid addition-products of an alkali salt with hydrogen peroxide and alkali salts of peroxo-acids in the presence of a sodium phosphate which is selected of sodium polyphosphates and sodium phyrophosphate and of water, and (b) drying the resulting granulate.
