Process for the continuous production of mixtures of substances and reaction mixtures and device for its implementation
First Claim
1. A process for the continuous production of an aqueous equilibrium peroxycarboxylic acid solution, comprising withdrawing individual components from storage containers or from distribution networks that form the equilibrium peroxycarboxylic acid solution including a lower carboxylic acid, aqueous hydrogen peroxide, water and a mineral acid catalyst, forming continuous streams of the individual components, conveying each component stream by a controlled system including a mass-flow or volume-flow measuring device and a regulating element for regulating the rate of flow, regulating mass flow-rates of the individual components in quantitatively proportional manner with reference to the mass flow-rate of a first component and introducing the regulated mass flow-rates of the individual components into a receiving container, immediately or after individual mass flow-rates have been completely or partially combined together to form a total stream, thereby bringing together the individual components forming the equilibrium peroxycarboxylic acid and, and measuring the flow of the total stream formed from the individual streams or measuring the total quantity of the individual or partial streams fed into the container and balancing total flows against the sum of the individual streams, and, allowing the mixture of substances to stand in a container until a desired conversion has been established.

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 The component streams withdrawn from a storage container (1, 2 or 3) or a distribution network (12) are each conveyed via a controlled system (22, 23, 24, 25) which in each instance comprises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.
