Die in der Mineralölraffinerie bei Behandlung der zu raffinirenden OeIe mit Schwefelsäure sich ergebenden sogen. Brandharze haben bislang eine befriedigende Verwendung nicht gefunden. Dieselben lassen sich, wie zahlreiche Versuche erwiesen haben, in folgender, sehr einfacher Weise auf ein vorzügliches. Anstrichmittel für Eisen und für Metalle jeder Art, sowie für Holz, Steine und dergl. verarbeiten. In the mineral oil refinery, when the oils to be refined are treated with sulfuric acid resulting so-called. Fire resins have not yet had a satisfactory use found. As numerous experiments have shown, these can be found in the following very simple way in an excellent way. Paints for iron and for metals everyone Art, as well as for wood, stones and the like. Process.
Die Brandharze werden zunächst von der ihnen noch stets beigemengten freien Schwefelsäure befreit, sei es durch Erhitzen oder durch Erwärmen mit Kalkwasser, in welchem Falle die freie Säure unter Bildung von schwefelsaurem Kalk gebunden wird. Man erhöht sodann die Temperatur vortheilhaft auf circa .300° C. und setzt die Masse dieser hohen Temperatur zweckmäfsig in einer Retorte so lange aus, bis sie in ein völlig festes Product übergegangen ist. Letzteres wird sodann in geeigneten Lösungsmitteln,, wie Petroleum, Benzin, Terpentinöl u. s. w., gelöst.The fire resins are initially removed from the free sulfuric acid that is still added to them freed, be it by heating or by warming with lime water, in which case the free acid is bound with the formation of sulphate of lime. The temperature is then advantageously increased to approx .300 ° C. and expediently sets the mass of this high temperature in a retort like this long until it has turned into a completely solid product. The latter is then used in suitable solvents, such as petroleum, gasoline, turpentine oil and so on.
Nach der Patentschrift.3577 werden die bei der Mineralölreinigung sich ergebenden Abfallstoffe nach erfolgter Neutralisation der Schwefelsäure lind nach dem Abdestilliren der niedriger siedenden Antheile einem energischen Oxydationsprocefs unterworfen, sei es, indem man bei 150 bis 2000 48 Stunden lang Luft durch sie leitet oder indem man sie mehrere Tage in offenen Gefäfsen auf 100 bis 1 50° erwärmt.According to Patent Specification 3577, the waste materials resulting from mineral oil cleaning after the sulfuric acid has been neutralized and after the lower boiling components have been distilled off are subjected to an energetic oxidation process, either by passing air through them at 150 to 200 0 for 48 hours or by they are warmed to 100 to 150 ° for several days in open vessels.
Für das vorliegende Verfahren kommt eine Oxydation, welche das Wesentliche des Verfahrens der Patentschrift 3577 bildet, nicht in Betracht. Die Brandharze werden einfach in einer Retorte auf ca. 3000 erhitzt, wobei zunächst natürlich leichter siedende Antheile entweichen; dann aber vollzieht sich lediglich unter dem Einflufs der hohen Temperatur, ohne Oxydation, eine Umwandlung der Masse, wie sich daraus ergiebt, dafs 1. die Masse unmittelbar nach dem Verflüchtigen der leichter siedenden Antheile keineswegs schon für den in Rede stehenden Zweck verwendbar ist, und 2. sie durchaus brauchbar wird, wenn man den Zutritt von Luft während des Erhitzens auf ca. 3oo° direct völlig verhindert.For the present process, an oxidation, which is the essence of the process of Patent 3577, is out of the question. The fire resins are simply heated in a retort at about 300 0, initially, of course, lower boiling Antheile escape; but then, under the influence of the high temperature, without oxidation, a transformation of the mass takes place, as follows from the fact that 1. immediately after the volatilization of the lower-boiling parts, the mass is by no means usable for the purpose in question, and 2. It becomes entirely usable if the admission of air is completely prevented during the heating to about 300 ° direct.
Durch vorstehend beschriebenes Verfahren wird ein bisher lästiges Abfallproduct in einfacher und lucrativer WTeise für gewerbliche Zwecke nutzbar gemacht.By the method described above a previously troublesome waste product in a simple and lucrativer W T is harnessed else for commercial purposes.

Verfahren zur Herstellung eines Anstrichmittels, dadurch gekennzeichnet, dafs man die bei der Schwefelsäurebehandlung der Mineralöle sich ergebenden sogen. Brandharze zunächst von noch anhaftender freier Schwefelsäure befreit und sodann hohen Temperaturen, bei denen indefs noch keine Zersetzung unter Kohleabscheidung erfolgt, aussetzt, bis eine völlig feste Masse entsteht, worauf man diese in geeigneten Lösungsmitteln löst.Godfather saying:
Process for the production of a paint, characterized in that the so-called resulting from the sulfuric acid treatment of the mineral oils. Fire resins are first freed from still adhering free sulfuric acid and then exposed to high temperatures, at which, however, no decomposition with carbon deposition occurs, until a completely solid mass is formed, whereupon this is dissolved in suitable solvents.
