Description
Verfahren zur Herstellung heller Harzlösungen. Die bei der Reinigung der leichten Öle des Steinkohlenteers durch Schwefelsäure fallende sogenannte Abfallsäure nimmt aus den zu reinigenden Ölen gewisse Verunreinigungen auf, welche unter dem Einfluß der Schwefelsäure eine mehr oder weniger tief gehende Umsetzung erfahren und dabei harzartige Produkte bilden. Vorliegende Erfindung bezweckt, diese harzartigen Produkte in einer Form zu gewinnen, in welcher sie sowohl selbst als Lackkörper benutzt werden können, als. auch besonders als trocknende Zusätze zu anderen Lackkörpern, insbesondere zu Cumaronharzlack Anwendung finden können. Wesentlich ist hierbei, daß die Harzkörper aus der Abfallsäure in einem möglichst hellen Zustande gewonnen werden, da andernfalls ihre Verwendung als Lack oder Lacksikkativ nicht wohl in Frage kommt.Process for the preparation of pale resin solutions. The one when cleaning of the light oils of coal tar, so-called waste acid falling through sulfuric acid picks up certain impurities from the oils to be cleaned, which are under the Influence of sulfuric acid experience a more or less profound conversion and thereby form resinous products. The present invention aims to provide these resinous Obtain products in a form in which they can be used as a lacquer body can be used as. also especially as drying additives to other paint bodies, can be used in particular for coumarone resin varnish. It is essential here, that the resin body obtained from the waste acid in the lightest possible condition otherwise their use as a varnish or varnish siccative would not be in Question comes.
Gemäß der vorliegenden Erfindung werden die harzartigen Bestandteile der Abfallschwefelsäure dadurch in verhältnismäßig hellem Zustande gewonnen, daß man sie in Benzolkohlenwasserstoffen aufnimmt. Die Säure wird von den Harzbestandteilen in bekannter Weise ducrh Zufügung von Wasser entfernt, wobei nur darauf zu achten ist, daß die Lösungswärme der Schwefelsäure in Wasser die Reaktionsmasse nicht so hoch erwärmt, daß eine schädlicEe Dunkelfärbung der Harzkörper eintritt. Das spezifische Gewicht der Harzlösung muß stets kleiner sein als das der verdünnten Säure, damit sie nicht untersinkt oder sich mit der verdünnten Säure vermischt und untrennbare Suspensionen bildet.According to the present invention, the resinous ingredients the waste sulfuric acid obtained in a relatively pale state in that they are taken up in benzene hydrocarbons. The acid is from the resin components removed in a known manner by adding water, being careful only is that the heat of dissolution of sulfuric acid in water does not affect the reaction mass highly heated that a harmful darkening of the resin body occurs. The specific The weight of the resin solution must always be less than that of the dilute acid, so they do not sink or mix with the dilute acid and are inseparable Forms suspensions.
Die Härzlösüng in den Benzolkohlenwasserstoffen kann Harzlacken unmittelbar zugesetzt werden und wirkt dann günstig auf die Trocknung der Lackanstriche, insbesondere wenn der Lack mit Cumaronharz angesetzt war. Man kann die Harzkörper auch von dem Lösungsmittel isolieren und gewinnt sie dann in Form eines hellgelben Pulvers. Die helle Farbe des gewonnenen Harzpulvers hängt hierbei davon ab, daß das Lösungsmittel aus Benzolkohlenwasserstoffen besteht, deren Siedepunkt so tief liegt, daß beim Abtreiben des Lösungsmittels keine zerstörenden Umsetzungen des Harzes, die mit einer Dunkelfärbung verknüpft . sind, eintreten. Auch das Pulver kann als Zusatz. zu Lacken benutzt werden und wirkt dann ebenfalls trocknend, insbesondere auf Cumaronharzlackanstriche.The Harzlösüng in the benzene hydrocarbons can resin varnishes directly are added and then has a beneficial effect on the drying of the paint coatings, in particular if the paint was set with coumarone resin. You can also get the resin body from the Isolate solvents and then recover them in the form of a light yellow powder. the light color of the resin powder obtained depends on the solvent consists of benzene hydrocarbons whose boiling point is so low that the Driving off the solvent does not have any destructive reactions of the resin with linked to a dark color. are to enter. The powder can also be used as an additive. used to paint and then also has a drying effect, especially on coumarone resin paints.
