Abstract: PCT No. PCT/EP94/00422 Sec. 371 Date Sep. 28, 1995 Sec. 102(e) Date Sep. 28, 1995 PCT Filed Feb. 15, 1994 PCT Pub. No. WO94/20413 PCT Pub. Date Sep. 15, 1994The invention relates to a method for increasing the storage stability of sodium percarbonate (2 Na2CO3.3 H2O2) by coating with a sodium perborate. According to the present invention wet sodium percarbonate salt, obtained by reacting sodium carbonate with hydrogen peroxide in aqueous phase and separating the salt from the aqueous phase, is treated with a solution or suspension containing sodium perborate in a solid-liquid separator by a kind of displacement wash. In contrast to previously known methods, according to the present invention a greater storage stability is attained with smaller quantities of perborate coating.

Abstract: In the prior art, sodium percarbonate is coated with compounds which produce a stabilizing action in order to increase the shelf life. There is a need for an improved, boron-free, coating for sodium percarbonate. Proposed by the invention is a particle coating containing sodium carbonate plus one or more optionally partly hydrated magnesium compounds, preferably magnesium sulphate, in a single coat or in separate coats. The coating preferably contains two coats. The particles are produced by spraying aqueous solutions containing the coating compounds on to sodium percarbonate in a fluidized bed and at the same time evaporating off the water. Their long shelf life makes particles coated in this way suitable for use in washing, bleaching and cleaning agents.

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: Reactions between at least two fluid reactants are performed in a reactor comprising wall elements (1), slot- shaped reaction spaces (3) and cavities (5) for conducting a fluid heat-carrier through. Depending on the process and throughput, a modular structural design is chosen wherein an arbitrary number of wall elements (1) are assembled to a right-parallelepipedal block (24), the reaction spaces (3) are formed between lateral surfaces (2) of right- parallelepipedal wall elements (1), the reactants are introduced into the reaction spaces (3) from edge regions of one side of the block (24) and are conducted through the reaction spaces (3) in parallel flows and the fluid heat- carrier is conducted through the tubular cavities (5) extending in the interior of the wall elements (1).

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.
