摘要： The use of lactobionic acid, lactobionic acid salts and/or lactobionic acid derivatives as covering material is disclosed for coating alkali metal peroxy salts, in particular for coating sodium percarbonate. In an advantageous alternative of the invention, alkali metal peroxy salts are provided with a covering layer that contains as covering materials lactobionic acid and/or lactobionic acid salt mixed with boric acid and/or a boric acid salt as additional covering material. This coating stabilizes the alkali metal peroxy salts and protects them against humidity and decomposition.

In some embodiments at least a fraction of the mother liquor introduced into the dissolution tank is obtained by extraction from the reaction vessel and in other embodiments a fraction of the sodium percarbonate is introduced in solution in the mother liquor and a fraction is introduced in particulate form directly into the reaction vessel. Large particle sodium percarbonate is provided which has a 7 day aged heat emission at 40C. of not more than 3 &mgr;W/g measured in a microcalorimeter over 16 hours that is lower than the heat emission from conventionally produced sodium percarbonate employing a chloride salting-out agent.

摘要： A method for the “dry” production of sodium percarbonate (dry process), in which monohydrate crystals of sodium carbonate are reacted with a quasi-stoichiometric quantity of concentrated aqueous hydrogen peroxide solution, relative to the quantity of active oxygen required in the sodium percarbonate to be produced. This method can be combined to great advantage with subsequent compaction of the sodium percarbonate obtained. Sodium percarbonate products containing varying concentrations of active oxygen of at least 10 weight percent, particularly high active oxygen concentrations of above 14.5 weight percent, can be produced. The resulting sodium percarbonate products are distinguished in that they have remarkably advantageous dissolution rates, stabilities and compatibility with detergent bases, and are superior to conventional sodium percarbonates obtained, for example, by a crystallization process. The invention also relates to the sodium percarbonate products obtained and to detergent compositions containing such sodium percarbonate products.

摘要： A flexible process for production of homogeneous sodium precarbonate particles or granules according to which a reaction slurry with an average to high solids content is prepared initially from an aqueous hydrogen peroxide solution of up to maximum 50% by weight and solid soda, this reaction slurry, which optionally may be finely ground by wet comminution, being subsequently subjected immediately to short-term drying, preferably spray drying, and, optionally, granulation. The process enables production, in an efficient manner, of essentially homogeneous sodium percarbonate particles or granules with variable active oxygen contents of 10 to 14.5% by weight and grain sizes and bulk densities which are variable within wide ranges.
