    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 process for producing granular sodium percarbonate by fluidized bed buildup granulation comprises the spraying of an aqueous solution of hydrogen peroxide and of an aqueous solution of sodium carbonate with at least one multisubstance nozzle with external mixing into a fluidized bed comprising sodium percarbonate particles and simultaneously evaporating water, and is characterized in that the solution of sodium carbonate additionally comprises sodium carbonate and/or sodium percarbonate in suspended form and is passed through a dispersing apparatus for dispersion of solids before being fed to the multisubstance nozzle.The process allows the blockage of the multisubstance nozzle to be avoided and sodium percarbonate dust to be recycled from the offgas stream of the fluidized bed into the granulation.

    摘要： The invention relates to the continuous production of epoxide resins of low, medium and high molecular weight, and also to their purification and to that of the waste water. No raw materials are required in addition to epichlorohydrin, 2,2-bis-(4-hydroxyphenyl)-propane, alkali hydroxide and water. The raw materials are fed at a shear rate of 7.5-50.times.10.sup.4 sec.sup.-1 (at a peripheral speed of the rotor of 15 to 50 m/sec and a distance of the rotor elements from the stator elements of 0.01 to 0.02 cm) continuously into a reactor and mixed in such a way that by the concentration of high kinetic energy in a very limited space the interfaces of the phases of the heterogeneous reaction mixture are increased to an extreme extent and the reagents are caused to react with one another within 5 sec. at the latest.The reaction proceeds very evenly in the reactor. By conversion of the kinetic energy and reaction heat of the chemical reaction the necessary reaction temperature is maintained for the reaction system within the reactor. The resins obtained and also their waste water are extracted in a pulsation unit in a counterflow, by means of water or organic solvents. This process enables epoxide resins of superior quality to be economically produced. The contamination of the waste water can be thus reduced to a minimum.
