    Abstract: An aqueous solution of hydrogen peroxide is produced by direct synthesis from hydrogen and oxygen in the presence of a heterogeneous catalyst. According to the invention, a gas mixture comprising H2 and O2, essentially saturated or supersaturated with water (=containing fog) is fed into a reactor containing the catalyst. The volume ratio of the gas mixture fed in (standard liters per hour) to liquid removed (liters per hour) is adjusted to a value equal to or greater than 15,000, especially 20,000 to 50,000, and the gas mixture leaving the reactor is recycled after replenishment with H2, O2, and H2O vapor. Solutions with high H2O2 concentration can be obtained according to the invention without additional concentration.

    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.
