Abstract: Fluidized-bed coating of peroxy compounds, especially sodium percarbonate for use in detergent and bleaching products. Production of coated peroxy compounds by fluidized-bed coating comprises spraying an aqueous coating solution onto particles of the peroxy compound in a fluidized-bed chamber and drying the coating by means of a fluidizing gas injected through a radial distributor plate at a fluidized bed temperature of 30-70 degrees C, where the fluidizing gas emerges (upwards) from openings in the distributor plate at an angle of less than 35 degrees to the horizontal and the coating solution emerges (downwards) from spray nozzles at the same angle.

Abstract: Sodium percarbonate of the formula 2 Na2CO3 3 H2O2 can be produced by fluidised-bed spray granulation by spraying an aqueous solution of sodium carbonate and a hydrogen peroxide solution on sodium percarbonate seeds and evaporating water. The previously necessary use of phosphorus-containing crystallisation inhibitor to prevent blockages and incrustations in and on the nozzle can be avoided by the invention if the solutions are sprayed using a single three-substance pulverisation nozzle with the external mixing of the solutions.

Abstract: The invention concerns washing, bleaching and cleaning agent compositions containing coated alkali metal percarbonate, in particular sodium percarbonate, and conventional components of such compositions, including in particular silicate-like builders. Compositions according to the invention, which have good stability during storage yet dissolve rapidly and thus render extension of the washing, bleaching or cleaning period unnecessary, contain an alkali metal percarbonate with an Oa* content in the composition of at least 70 %, a dissolution time of the alkali metal percarbonate in water of less than 10 minutes, determined under specific test conditions in each case, and a morphology index MI greater than 0.03, in particular greater than 0.04, in which: MI = 0.0448 . CV + 3.61 . 106 . d-3; CV = .sigma./d; .sigma. = .SIGMA.(di-d)2.wi/100 and d = .SIGMA.di.wi/100.

Abstract: Two reactants are introduced into a slot-shaped reaction space (3) of a reactor. The space is formed between lateral surfaces (2) of two equally large and right parallelepipedal wall elements (1) comprising solid plates. The reactants are introduced from the edge of the slot-shaped reaction spaces situated on the same side of the block. Two reactants are introduced into a slot-shaped reaction space of a reactor. The spaces are formed between lateral surfaces of two equally large and right parallelepipedal wall elements comprising solid plates. The wall elements are arranged interchangeably in a block within the virtual parallelepiped. The reactants are introduced from edge regions of the slot-shaped reaction spaces situated on the same side of the block. The reactants are conducted as a reaction mixture through the reaction spaces in the same direction in parallel flows. A fluid heat exchange medium is conducted through tubular cavities (5) extending in the interior of the wall elements to obtain the desired reaction. An independent claim is also included for apparatus comprising the reactor in which the slot-shaped reaction spaces are capable of having the reactants supplied from the same side of the block. The reaction spaces are oriented to guide the reaction mixture in the same direction in parallel flows.

Abstract: The invention relates to a process for the production, by fluid-bed spray granulation, of granular sodium percarbonate having a low TAM value. According to the invention, in the fluid-bed spray granulation, an Mg compound in a quantity of 50 to 2,000 ppm, in particular 100 to 1,000 ppm, or/and a complexing agent from among the hydroxycarboxylic acids, aminocarboxylic acids, aminophosphonic acids and phosphonocarboxylic acids, hydroxyphosphonic acids and their alkali metal salts, ammonium salts or Mg salts, in a quantity of 50 to 2,000 ppm, in particular 200 to 1,000 ppm, are added as stabilisers to the soda solution and/or H 2 O 2 solution. Preferably a combination of an Mg compound in a quantity of 100 to 1,000 ppm Mg 2+ and waterglass in a quantity of 0.1 to 1 wt. %, in particular 0.1 to 0.5 wt. %, is used, and in this case granules having a TAM value of about or below 6 muW/g and simultaneously a short dissolving time, are obtainable.
