Description
Bekanntlich entstehen bei der Kondensation von fettaromatischen Ketonen mit Formaldehyd in Gegenwart alkalischer Kondensationsmittel je nach den angewandten Arbeitsmethoden schmelzbare oder nicht schmelzbare Harze (vgl. Patentschrift 402 996). Diese in Leinöl, Äthylalkohol und Testbenzin unlöslichen Harze gehen unter verhältnismäßig milden Hydrierungsbedingungen in alkohollösliche Harze über; unter energischeren Bedingungen können leinöllösliche Harze erhalten werden, die in 94o/oigem Alkohol in der Kälte nur noch trüb löslich sind, während unter noch energischeren Bedingungen in Testbenzin lösliche Harze entstehen, die in 94o/oigem Alkohol unlöslich, jedoch in Leinöl noch löslich sind. Führt man die Hydrierung im kontinuierlichen Betrieb in GegenwartvonLösungsmitteln, wie Butanol, Dioxan oder Essigester, durch, so können nach längerem Betrieb Störungen durch Abschneidung fester Produkte im Hydrierofen eintreten, so daß die Hydrierung abgebrochen werden muß.It is well known that the condensation of fatty aromatic ketones is formed with formaldehyde in the presence of alkaline condensing agents depending on the applied Working methods meltable or non-meltable resins (see patent specification 402 996). These resins, which are insoluble in linseed oil, ethyl alcohol and white spirit, perish relatively mild hydrogenation conditions in alcohol-soluble resins; under In more vigorous conditions, linseed oil-soluble resins can be obtained, which are in 94% Alcohol in the cold are only cloudy, while under still more energetic Resins which are soluble in white spirit and are insoluble in 94% alcohol are formed, however are still soluble in linseed oil. If the hydrogenation is carried out continuously Operation in the presence of solvents such as butanol, dioxane or ethyl acetate, After long periods of operation, malfunctions due to solid products being cut off in the Enter hydrogenation furnace, so that the hydrogenation must be stopped.
Es wurde nun gefunden, daß man die erwähnten Harze in Gegenwart von
Lösungsmitteln störungsfrei kontinuierlich hydrieren kann, wenn man als Lösungsmittel
oberhalb etwa 18o° siedende, unter den Reaktionsbedingungen indifferente organische
Verbindungen verwendet, die sowohl das zu hydrierende Harz als auch entstehende
Hydrierungsprodukte zu lösen vermögen. Organische Verbindungen dieser Art sind z.
B. hochsiedende Äther, Ester und Alkohole, insbesondere die Monoalkyläther des Diäthylenglykols.
Die Abtrennung der als Lösungsmittel verwendeten Verbindung erfolgt
