摘要： A process for the preparation of coated peroxygen compounds, in particular sodium percarbonate, by fluidized bed coating. By using a fluidized bed reactor with a radial inflow base, the passage openings of which allow the fluidized bed gas to emerge in the region of the opening at an angle of less than 35°, measured with respect to the horizontal, in the form of directed part streams, and in which are arranged spray nozzles, the pulse of which points in the same direction as the pulse of the fluidizing gas, it is possible to obtain products with an increased active oxygen stability. A circular reactor, the inflow base of which has lamellae overlapping like turbine blades and nozzles aligned in the direction of rotation of the fluidized bed is preferred.

摘要： The invention relates to coated peroxygen compounds, in particular coated sodium percarbonate particles, with a delayed release of the active oxygen (=increased dissolving time). Particles according to the invention comprise an innermost shell layer, comprising at least one hydrate-forming inorganic salt, and an outer shell layer, comprising 0.2 to 3 wt. % alkali metal silicate with a modulus of greater than 2.5, in particular 3 to 5, the outer layer having been prepared using an alkali metal silicate solution with an alkali metal silicate concentration in the range from 2 to 20 wt. %. By lowering the alkali metal silicate concentration in the solution to be used, the dissolving time can be increased for the same shell amount. The dissolving time can be increased greatly by the layer sequence and the concentration of the solution, at a low amount of alkali metal silicate.
