Description
Verfahren zur Herstellung harzartiger Körper und Kunststoffe aus Selektivextrakten der 1VIineralölraffination Es ist bekannt, daß man Säureteere durch Behandlung mit Salpetersäure oder Essigsäure in harzartige Körper überführen kann. Die in den Säureteeren enthaltene Schwefelsäure ist nicht nur ein schwer auswaschbarer Bestandteil des Endproduktes, sondern beeinflußt auch die Verharzung ungünstig.Process for the production of resinous bodies and plastics from selective extracts 1VIineralölrefination It is known that acid tars can be treated with Nitric acid or acetic acid can transfer into resinous bodies. The ones in the acid tars The sulfuric acid contained is not only a difficult-to-wash component of the End product, but also has an adverse effect on resinification.
Es wurde gefunden, daß durch Einwirkung von Salpetersäure, nicht jedoch von Essigsäure, auf die Extrakte, die durch die Verwendung selektiver Lösungsmittel, wie Furfurol, Schwefeldioxyd od. dgl., aus Mineralölen gewonnen wurden, gleichfalls harzartige Körper entstehen, die die nachteiligen Eigenschaften der aus Säureteeren hergestellten Harze nicht aufweisen.It has been found that by exposure to nitric acid, however, not of acetic acid, on the extracts obtained through the use of selective solvents, like furfural, sulfur dioxide or the like, obtained from mineral oils, likewise Resin-like bodies arise which have the adverse properties of acid tars produced resins do not have.
Es wurde weiter gefunden, daß man die Selektivextrakte durch Destillation, am besten im Vacuum, in einen trocknenden und einen nichttrocknenden Anteil zerlegen kann und daß beide Anteile, insbesondere aber das nichttrocknende Destillat, durch Salpetersäure in harzartige, braune Produkte übergeführt werden können. Während die Selektivextrakte selbst und das Destillat mit Polyvinylchlorid und Nitrocellulose nicht verträglich sind, lassen sich die durch Salpetersäurebehandlung gewonnenen Produkte mit Nitrocellulose und chlorierten Kohlenwasserstoffen, insbesondere Polyvinylchlorid und Chlorkautschuk, unter Bildung neuartiger wertvoller Kunststoffe umsetzen. Mit Polyvinylchlorid entsteht dabei eine zugelastische, dunkle Masse, die völlig wasserfest ist und sich hervorragend als wasserfester Anstrich, insbesondere für Keller- und Tunnelbauten, eignet.It was also found that the selective extracts by distillation, best to split it in a vacuum into a drying and a non-drying part can and that both parts, but especially the non-drying distillate, through Nitric acid can be converted into resinous, brown products. While the selective extracts themselves and the distillate with polyvinyl chloride and nitrocellulose are not compatible, those obtained by treatment with nitric acid can be used Products with nitrocellulose and chlorinated hydrocarbons, especially polyvinyl chloride and chlorinated rubber, with the formation of new valuable plastics. With Polyvinyl chloride creates an elastic, dark mass that is completely waterproof is and is excellent as a waterproof coating, especially for basement and Tunnel construction, is suitable.
Beim Erhitzen der Harzkörper über rzo° findet, vermutlich durch Oxydation, eine weitere Verharzung statt, wodurch die Harze härter werden und wobei die überschüssige Säure verdampft, so daß ein Auswaschen nicht mehr erforderlich ist.When the resin body is heated above rzo °, probably through oxidation, further resinification takes place, which makes the resins harder and the excess acid evaporates so that washing out is no longer necessary is.
Die neuen Harze sind, in Xylol, Benzol oder Testbenzin gelöst, wertvolle Lackrohstoff. Sofern die Harze mit chlorierten Kohlenwasserstoffen kombiniert sind, lösen sie sich nur in Cyclohexanon, Methylcyclohexanon, Monostyrol, Methylchlorid bzw. Mischungen dieser Lösungsmittel untereinander.The new resins are valuable when dissolved in xylene, benzene or white spirit Lacquer raw material. If the resins are combined with chlorinated hydrocarbons, they only dissolve in cyclohexanone, methylcyclohexanone, monostyrene, methyl chloride or mixtures of these solvents with one another.
BeiSpiele i. ioo Teile Furfürolextrrakt werden mit 6o Teilen 98o/oiger Salpetersäure bei etwa 9o° zur Reaktion gebracht. Nach Beendigung der Reaktion wird vorsichtig auf 14o° erhitzt, bis das Schäumen aufhört. Es entsteht ein rotbraunes, säurefreies, sprödes Harz, das inXylol gelöst, mitEisenoxydrot und Zinkoxyd pigmentiert, einen haltbaren Rostschutzanstrich ergibt.Examples i. 100 parts of Furfürolextrrakt are combined with 60 parts 98% Nitric acid reacted at about 90 °. After the reaction is finished carefully heated to 14o ° until foaming stops. The result is a red-brown, acid-free, brittle resin, which is dissolved in xylene, pigmented with iron oxide red and zinc oxide, results in a durable anti-rust coating.
2. ioo Teile Fu.rfurolextrakt werden in Gegenwart von 5 Teilen Polyvinylchlorid mit 6o Teilen 98o/oiger Salpetersäure, wie in Beispiel i angegeben, behandelt. Das Reaktionsprodukt zeigt zugelastische Eigenschaften und stellt mit io o/o Phthalsäureester gemischt, einen völlig wasserfesten Isolieranstrich das. Das Produkt kann entweder in geschmolzenem Zustand oder in Cyclohexanon gelöst verwendet werden.2. 100 parts of Fu.rfurolextrakt are in the presence of 5 parts of polyvinyl chloride treated with 60 parts of 98% nitric acid, as indicated in Example i. That Reaction product shows elastic properties and represents with io o / o phthalic acid ester mixed, a fully waterproof insulating paint. The product can either can be used in the molten state or dissolved in cyclohexanone.
