Verfahren zur Herstellung von Lacitgrundmassen und hartgummiähnlichen Produkten
Es ist bekannt, dass schwarze, krümelige, spröde Massen entstehen, welche bis heute keinen technischen Wert besitzen, wenn Furfurol mit Säuren erwärmt wird.
Es wurde gefunden, dass schöne, schwarze, glänzende, hartgummiähnliehe Massen erzielt werden, wenn Furfurol nicht allein, sondern zusammen mit Teerölen in Anwesenheit von Schwefelsäure, Phosphorsäure oder Salzsäure oder organischen Verbindungen der Schwefelsäure (z. B. Phenolsehwefelsäure) oder von Säure abspaltenden Stoffen usw. erhitzt wird. Die so erzielten Massen können durch Erhitzen auf höhere Temperatur fester und härter gemacht werden. Unter Teerölen werden im vorliegenden Falle sämtliche Rohteeröle verstanden, also Leicht-, Mittel-und Schweröle, sowie Anthrazenöle, die aus gewöhnlichem Steinkohlenteer oder Tieftempera. turteer oder Braunkohlenteer gewonnen sein können.
Beispiel : 100 Teile Furfurol und 100 Teile eines sauren Teeröles werden in Anwesenheit von 3 bis 10 Teilen (je nach der Teerart) konzentrierter Schwefelsäure, am besten unter Druck (1-6 Atm.) auf 130-1750 erhitzt : Es bildet sich in dieser Zeit ein Kondensationsprodukt, aus dem etwa noch vorhandene ölige Substanzen mit einem Lösungsmittel, z. B. Chlorkohlenwasserstoff, extrahiert werden können.
Danach kann die Masse allein oder unter Zumischung von Füllstoffen in Formen unter weiterem Erhitzen zu schönen, hartgummiartigen Gegenständen gepresst werden.
Durch Zusatz von wasserfreier Phosphorsäure oder Einlassen von Salzsäuregas kann die Kondensation verbessert werden, da diese Säuren das bei der Kondensation freiwerdende Wasser binden.
Die Kondensation kann auch ohne Schwefelsäure nur in Gegenwart von gasförmiger Salzsäure oder Phosphorsäure bzw. einem Gemisch dieser Säuren hervorgerufen werden. Ferner können statt Schwefelsäure auch organische Verbindungen der Schwefelsäure (z. B. Äthylschwefelsäure, Phenolsehwefel- säure u. dgl. ) verwendet werden.
Der Prozess geht auch bei gewöhnlichem Druck vor sich, aber nur in träger Weise, während er bei Überdruck glatt und schnell vonstatten geht. Der Überdruck wird zweckmässig durch inerte Gase wie Stickstoff, Kohlensäure usw. erzielt.
Kondensiert man in Gegenwart von 10-30 Teilen Paraformaldehyd, so wird dem Produkt eine höhere Löslichkeit in einigen organischen Lösemitteln erteilt, so dass diese Stoffe auch als Lackgrundstoffe verwendet werden können. Anstatt Paraformaldehyd kann auch Hexamethylentetramin oder ein anderes Polymerisations-oder Kondensationsprodukt des Formaldehyds verwendet werden.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Lackgrundmassen und hartgummiähnlichen Produkten, dadurch gekennzeichnet, dass Furfurol und Teeröle mit Säuren, z. B. Schwefelsäure, Salzsäuregas, Phosphorsäure oder organischen Sehwefelsäureverbindungen erhitzt werden, u. zw. vorteilhaft unter erhöhtem Druck (1-6 Atm.), der zweckmässig durch inerte Gase erzeugt wird.

Process for the production of lacite bases and hard rubber-like products
It is known that black, crumbly, brittle masses are formed, which to this day have no technical value when furfural is heated with acids.
It has been found that beautiful, black, shiny, hard rubber-like masses are achieved when furfural is not used alone, but together with tar oils in the presence of sulfuric acid, phosphoric acid or hydrochloric acid or organic compounds of sulfuric acid (e.g. phenol sulfic acid) or substances that split off acids etc. is heated. The masses obtained in this way can be made stronger and harder by heating to a higher temperature. In the present case, tar oils are understood to mean all crude tar oils, that is to say light, medium and heavy oils, as well as anthracene oils, which are made from common coal tar or low tempera. turteer or lignite tar can be obtained.
Example: 100 parts of furfural and 100 parts of an acidic tar oil are heated to 130-1750 in the presence of 3 to 10 parts (depending on the type of tar), preferably under pressure (1-6 atm.): It is formed in this Time a condensation product from which any oily substances still present with a solvent, e.g. B. chlorinated hydrocarbon, can be extracted.
Afterwards, the mass can be pressed into beautiful, hard rubber-like objects alone or with the addition of fillers in molds with further heating.
The condensation can be improved by adding anhydrous phosphoric acid or letting in hydrochloric acid gas, since these acids bind the water released during the condensation.
Even without sulfuric acid, the condensation can only be brought about in the presence of gaseous hydrochloric acid or phosphoric acid or a mixture of these acids. Furthermore, instead of sulfuric acid, organic compounds of sulfuric acid (for example ethylsulphuric acid, phenol / sulfuric acid and the like) can also be used.
The process also goes on under normal pressure, but only in a sluggish manner, while under overpressure it takes place smoothly and quickly. The overpressure is expediently achieved using inert gases such as nitrogen, carbonic acid, etc.
Condensation in the presence of 10-30 parts of paraformaldehyde gives the product a higher solubility in some organic solvents, so that these substances can also be used as paint base materials. Instead of paraformaldehyde, it is also possible to use hexamethylenetetramine or another polymerization or condensation product of formaldehyde.
PATENT CLAIMS:
1. A process for the production of paint base masses and hard rubber-like products, characterized in that furfural and tar oils with acids, eg. B. sulfuric acid, hydrochloric acid gas, phosphoric acid or organic sulfuric acid compounds are heated, u. between. Advantageously under increased pressure (1-6 atm.), which is expediently generated by inert gases.
