    Abstract: The invention relates to a method and an arrangmement in which a percarboxylic acid product is prepared and used. Conventional methods include refrigerated transport and double storage of the percarboxylic acid product before the consumption thereof at its site of use. These expensive stages have now been eliminated carrying out the preparation in connection with the use.

    Abstract: A process for the continuous production of a mixture of substances or of a reaction mixture that has been formed by reaction of components contained therein. The component streams withdrawn from a storage container (1, 2 or 3) or a distribution network (12) are each conveyed via a controlled system (22, 23, 24, 25) which in each instance comprises a flow-measuring device (8, 9, 10, 11) and a regulating element (34, 35, 36, 37). The flow-rates of the individual components are regulated in quantitatively proportional manner with reference to the flow-rate of a first component. The resulting regulated flow-rates are introduced into a receiving container, either directly or after individual flow-rates have been completely or partially conducted together. The process and the device are especially suitable for the on-site production of mixtures of substances that cannot be transported or that can only be transported in elaborate manner, such as relatively highly concentrated solutions of peroxycarboxylic acid.
