Zur Darstellung von' Cumaronharz dienen die rohen Solventnaphtha und die Schwerbcfizole, Fraktionen des Teeres bzw. der Teeröle. Aus diesen Schwerbenzolen wurde das Cumaronharz bisher so gewonnen, daß die Schwerbenzole zuerst mit verdünnter Natronlauge "zwecks Befreiung von ' Phenolen und deren Homologen und hierauf mit verdünnter Schwefelsäure zwecks Befreiung von Basen gewaschen wurden, hierauf einer Polymerisation mit konzentrierter Schwefelsäure unterworfen und nach Abscheidung dieser und der üblichen Nachwaschung und Neutralisation der verbleibenden Öle das Cumaronharz durch Destillation abgeschieden wurde. Das so erhaltene Cumaronharz zeigt nun den Übelstand, daß es in Alkohol nicht löslich ist. Die Eigenschaft der Alkohollöslichkeit ist aber besonders deshalb er-Serve to represent 'coumarone resin the crude solvent naphtha and heavy fizole, Fractions of the tar or tar oils. The coumarone resin has so far been obtained from these heavy benzenes in such a way that the Heavy benzenes first with dilute sodium hydroxide solution "for the purpose of freeing them from phenols and their homologues and then with dilute sulfuric acid for the purpose of liberation from Bases were washed, then a polymerization with concentrated sulfuric acid subjected and after deposition of this and the usual post-washing and neutralization of the remaining oils, the coumarone resin is deposited by distillation became. The coumarone resin thus obtained now shows the disadvantage that it is not in alcohol is soluble. The property of alcohol solubility is therefore particularly important
ao wünscht, weil das Cumaronharz, welches ein vorzügliches Ersatzprodukt - für Naturharze darstellt, oft infolge Fehlens dieser Eigen-ao wishes because the coumarone resin, which is an excellent substitute for natural resins represents, often due to the lack of this characteristic

Durch Gewinnung eines alkohollöslichen Cumarön-. harzes gewinnt man die Möglichkeit, Naturharze auch da durch Cumaronharze zu ersetzen, wo es bisher nicht möglich war.. . cannot be used. By obtaining an alcohol-soluble coumarone. resin gives you the opportunity to replace natural resins with coumarone resins, where it was previously not possible.
Die Darstellung eines in Alkohol löslichen Cumaronharzes .gelingt nun überraschenderweise dadurch, daß man die Solventnaphtha oder die Schwerbenzole, ohne sie durch Waschen mit verdünnten Säuren und Alkalien von Phenolen und Basen zu befreien, oder nachdem man ihnen noch Phenole zugesetzt hat, in rohem Zustand der Polymerisation mit. aliphatischen oder aromatischen Sulfosäuren, wie beispielsweise Äthyisulfat, Benzolsulfosäure, Suifanilsäure, Phenolsultosäure, KresolsulfosäurcNaphthalinsulfosäure, Naphtensäure usw. oder konzentrierter bzw. rauchender Schwefelsäure oder eines Gemisches von konzentrierter bzw. rauchender Schwefelsäure mit organischen Säuren bzw. Sulfosäuren der oben genannten Art '.unterwirft. Die Phenole !,müssen in der Solvent- ^5 naphtha oder den Schwerbenzolen vorhanden sein, dagegen können die Basen entfernt sein. Die Wirkung der konzentrierten Schwefelsäure dürfte.aüf einer teilweisen Sulfonierung :. der" im Gemische vorhandenen Phenole be- ^o ruhen. Das so gewonnene Produkt wird in üblicher Weise gewaschen und aus der Lösung mittels Destillation das Cumaronharz in-bekannter Weise gewonnen. Dieses Produkt zeigt die Eigenschaft, in Alkohol löslich zu sein.The preparation of an alcohol-soluble coumarone resin succeeds, surprisingly, in that the solvent naphtha or heavy benzenes are freed from phenols and bases without washing them with dilute acids and alkalis, or after phenols have been added to them, in the raw state Polymerization with. aliphatic or aromatic sulfonic acids, such as ethyl sulfate, benzenesulfonic acid, sulfanilic acid, phenol sulfonic acid, cresol sulfonic acid, naphthalenesulfonic acid, naphthenic acid etc. or concentrated or fuming sulfuric acid or a mixture of concentrated or fuming sulfuric acid with organic acids or sulfonic acids of the type mentioned above. The phenols!, Must be present in the Solvent ^ 5 naphtha or heavy benzenes, however, the bases can be removed. The effect of the concentrated sulfuric acid is likely to result from a partial sulfonation:. The product obtained in this way is washed in the usual way and the coumarone resin is obtained from the solution by distillation in a known manner. This product has the property of being soluble in alcohol.
Die als Zusatz verwendeten Phenole können roh oder gereinigt sein. Gewöhnlich verwendet man Rohphenole. Die Sulfosäuren können in isoliertem Zustande verwendet. werden, doch benutzt man gewöhnlich Mischungen. Man kann das Sulfonierungsgemisch unmittelbar ohne vorherige Abstumpfung.der Schwefelsäure anwenden. The phenols used as additives can be raw or purified. Usually one uses raw phenols. The sulfonic acids can be used in an isolated state. but mixtures are usually used. One can use the sulfonation mixture apply immediately without dulling the sulfuric acid.
