Erhitzung aui eine genügend hohe Temperatur und während genügend langer Zeit gelöst wird, um eine vollständige Umwandlung des Betulins eintreten zu lassen. Im allgemeinen dürfte dieses Verfahren sich am besten für industrielle- Aut\Übung eignen, da es die Durchführung der Umwandlung bei niedrigeren Temperaturen ermöglicht und deshalb ein mehr farbloses Produkt gibt. Die zweckmässigste Temperatur und die Dauer der Erhitzung müssen auch in diesem Falle empirisch festgestellt werden.
PATENT-ANSPRÜCHE : l. Verfahren zur Behandlung von Betulin, um es für die Herstellung von Anstrichmitteln geeignet zu machen, dadurch gekennzeichnet, dass das Betulin für sich oder in einem das Betulin lösenden Mittel, beispielsweise Leinöl-oder Terpentinöl, gelöst, auf eine Temperatur über seinen Schmelzpunkt und während so langer Zeit erhitzt wird, dass es bei Abkühlung aus einer warmen, konzentrierten Lösung eines bei der Herstellung von Firnissen gewöhnlich benutzten Lösungsmittels nicht ausgeschieden wird und dass es bei dem Eintrocknen oder der Entfernung des Lösungs- mittels zu einer Masse mit harter glasartiger Struktur erstarrt.

Heating to a sufficiently high temperature and for a sufficiently long time is dissolved to allow complete conversion of the betulin to occur. In general, this process is believed to be best for industrial practice as it allows the conversion to be carried out at lower temperatures and therefore gives a more colorless product. The most appropriate temperature and the duration of the heating must also be determined empirically in this case.
PATENT CLAIMS: l. Process for the treatment of betulin in order to make it suitable for the production of paints, characterized in that the betulin by itself or in an agent which dissolves the betulin, for example linseed oil or turpentine oil, is dissolved to a temperature above its melting point and while so It is heated for a long time so that it does not precipitate when it cools from a warm, concentrated solution of a solvent commonly used in the manufacture of varnishes, and that when the solvent dries out or is removed it solidifies to a mass with a hard glass-like structure.
