weise Leinöl, zugeben. Die nach dem vorliegenden Verfahren erhaltenen Harze lösen sich leicht in fetten Ölen, und es erübrigt sich daher, bei ihrer Verarbeitung zu ÖIlacken ein längeres Erhitzen in Leinöl, wie es in der Schweizer Patentschrift Nr. 89243 vorgeschlagen wird. Für viele Zwecke lässt sich das nochmalige, besondere Einschmelzen des Harzes umgehen. Man kann das von der Flüssigkeit abgetrennte Harz auch in geeigneten Lösungsmitteln direkt in Lösung bringen.
Bei niedrigsiedenden Lösungsmitteln wie Alkohol, Benzol usw. wird das abgenutschte Harz zweckmässig vorgetrocknet, bei hochsiedenden, wie Leinöl, Holzöl
EMI2.2
Azeton usw. vorzüglich zur Herstellung von Lacken, Imprägnierungsmitteln, Polituren u. dgl., infolge ihrer guten Löslichkeit in fetten Ölen, z. B. Leinöl auch besonders zur Öllack- und Ölfarbenfabrikation. Die Harze sind weitgehend temperaturbeständig und können deshalb auch als Schutzanstrich von Heizkörpern, Kesseln usw. Verwendung finden. Sie stellen vermöge dieser Eigenschaften einen hochwertigen Ersatz für Sehellack, Kopal, Bernstein und andere Naturharze dar.
PATENT-ANSPRÜCHE :
1. Velfahren zur Veredlung von Aldehydharzen, dadurch gekennzeichnet, dass man die bei einer über 30 Reaktionstemperatur hinausgetriebenen Kondensation bzw. Polymerisation von Aldehyden erhaltenen Produkte vor oder nach ihrer Überführung in Hartharze in einem geeigneten Lösungsmittel löst und sie aus der Lösung wieder ausfällt.
2. Verfahren zur Veredlung von Aldehydharzen, dadurch gekennzeichnet, dass man die bei einer über 300 Realdionstemperatur himusgetriebenen Kondensation bzw. Polymerisation von Aldehyden erhaltenen Harze einer Behandlung mit Wasser, zweckmässig bei Gegenwart von SäUlen und in feiner Zerteilung unterwirft.

EMI2.1
wise linseed oil, add. The resins obtained by the present process dissolve easily in fatty oils, and there is therefore no need for prolonged heating in linseed oil when they are processed into oil varnishes, as is suggested in Swiss Patent No. 89243. For many purposes, the repeated, special melting of the resin can be avoided. The resin separated from the liquid can also be brought into solution directly in suitable solvents.
In the case of low-boiling solvents such as alcohol, benzene, etc., the suction-filtered resin is expediently predried, in the case of high-boiling solvents such as linseed oil, wood oil
EMI2.2
Acetone etc. excellent for the production of paints, impregnation agents, polishes, etc. Like., Due to their good solubility in fatty oils, z. B. linseed oil also especially for oil varnish and oil paint production. The resins are largely temperature-resistant and can therefore also be used as a protective coating on radiators, boilers, etc. Due to these properties, they represent a high-quality substitute for optical lacquer, copal, amber and other natural resins.
PATENT CLAIMS:
1. Velfahren for refining aldehyde resins, characterized in that the products obtained at a reaction temperature above 30 condensation or polymerization of aldehydes are dissolved in a suitable solvent before or after their conversion into hard resins and they precipitate out of the solution.
2. A process for upgrading aldehyde resins, characterized in that the resins obtained at a condensation or polymerization of aldehydes which are driven above 300 realdione temperature are subjected to a treatment with water, advantageously in the presence of columns and finely divided.
