Abstract

Spray drying alkoli metal percorbmates and perborates.. N6A. is carried out with sprayable material containing only the stable basic components, the carrier of the active oxygen being supplied to the sprayable material immediately before spraying, the mixture then being sprayed and dried in the spray tower. The carrier for the active oxygen is pref. hydrogen peroxide.

Description

Verfahren zur Nerstellung von Alkaliperboraten und -percarbonaten (Zusatz zur Patentanmeldung T 17 92 273.5) In dem Hauptpatent ... (Patentanmeldung P 17 92 273.5) wird ein Verfahren zur Herstellung von Alkaliperboraten und -Porcarbonaten durch Sprühtrocknen beschrieben, bei dem der Sprühansatz nur die stabilen Grundkomponenten der Perverbindungen enthält und der Aktivsauerstoffträger unmittelbar vor dem Zerstäuben in die stabilen Komponenten eingeführt wird, worauf das Gemisch bei üblichen Touiperaturen in den Sprübturm versprüht und in bekannter Weise dort getrocknet wird. Process for the production of alkali perborates and percarbonates (Addition to patent application T 17 92 273.5) In the main patent ... (patent application P 17 92 273.5) is a process for the production of alkali perborates and porcarbonates described by spray drying, in which the spray approach only the stable basic components contains the per compounds and the active oxygen carrier immediately before atomization is introduced into the stable components, whereupon the mixture at usual Touiperatures sprayed into the spray tower and dried there in a known manner.

T)e Temperaturen der Trocknungsluft wurden mit 60 bis 2000 C, die der Luft an Ausgang der Sprühvorrichtung, die etwa der des Sprühgutes entspricht, mit ca. 40 bis 700 c angegeben.T) e temperatures of the drying air were with 60 to 2000 C, the the air at the outlet of the spray device, which corresponds roughly to that of the spray material, indicated with approx. 40 to 700 c.

Es wurde nun weiter gefunden, dass auch Temperaturen bis 1000 C für die Luft am Ausgang der Sprühvorriohtung anwendbar sind.It has now been found that temperatures up to 1000 C for the air at the outlet of the spray device can be used.
