Description

Die vorliegende Erfindung betrifft Flachsöle, und zwar aus Flachswachs oder flachswachshaltigem Material erhältliche ölartige Stoffgemische.The present invention relates to flax oils, namely oil-like substance mixtures obtainable from flax wax or material containing flax wax.

Flachswachs, welches in der Rindenschicht des Flachses zu etwa 10 % enthalten ist, wurde in der Literatur schon beschrieben. Es soll im wesentlichen aus Fettsäureestern ; langkettiger Alkohole und Kohlenwasserstoffen bestehen (Technologie der Textilfasern, "Der Flachs", Band V, 1,1,1930, 129 - 141 und 283; Hofmeister Ber. 1903, 1047; Ullmanns Enzyklopädie der technischen Chemie, 18. Band, 1967, 287). Ein flachswachshaltiges Material fällt bei der Flachsaufbereitung, insbesondere beim Knicken und Schwingen des Röststrohs, beim Grünflachsknicken, bei der Verbaumwollung und auch noch in weiteren Stufen bis einschließlich dem Verspinnen an-in mehr oder weniger feinteiliger Form. Der grobe, Scheben und kurze Wergteile enthaltende Staub enthält Flachswachs in einer.Menge bis zu etwa 10 Gew.% und der feine und feinste Staub, wie er beispielsweise in der Spinnerei anfällt, in einer Menge bis zu etwa 25 Gew.%. Das Flachswachs kann durch Extraktion daraus, beispielsweise in kontinuierlicher Weise mit Lösungsmitteln, wie Aceton, Äthanol, Benzol und anschliessendem Abtreiben des Lösungsmittels gewonnen werden (GB-PS 630 274). Der Extraktion können z.B. auch Gemische der vorgenannten Stäube mit geringeren Mengen Hanfstaub unterworfen werden. Auch ist ein vorheriger Aufschluß der Flachsabfälle mit Wasser und Dampf bekannt (DE-PS 817 335). Es wurde nun gefunden, daß aus Flachswachs erhältliche Produkte wertvolle Eigenschaften aufweisen. Gegenstand der vorliegenden Erfindung sind danach Stoffgemische ölartiger Konsistenz, erhältlich

  • a) durch Wasserdampfdestillation von flachswachshaltigem Rohmaterial oder von aus solchem Rohmaterial durch Lösungsmittelextraktion und, gegebenenfalls nach Abtreiben des Lösungsmittels, gewonnenem Rohflachswachs und Isolierung der bei der Wasserdampfdestilla- tion in der Vorlage anfallenden spezifisch leichteren Phase, schwereren Phase und/oder wäßrigen Phase und deren Entwässerung oder Entwässerung des Gemischs der Phasen .
  • b) durch Behandlung von flachswachshaltigem Rohmaterial oder von aus solchem Rohmaterial durch Lösungsmittelextraktion, gegebenenfalls nach Abtreiben des Lösungsmittels, gewonnenem Rohflachswachs, gegebenenfalls nachdem das Rohmaterial oder das Rohflachswachs zuvor der Wasserdampfdestillation unterworfen waren, mittels wäßriger Säuren, Extraktion der dann alkalisch gemachten wäßrigen Lösung mit organischen, polaren Lösungsmitteln, insbesondere eines Siedepunktes bis zu etwa 80 - 85°C/ 96 kPa und Gewinnung daraus des lösungsmittelfreien Extrakts oder
  • c) durch fraktionierte Destillation flachswachshaltiger - Lösungen in organischen Lösungsmitteln unter Gewinnung der Fraktion von 90 - 150°C/96 kPa.
Flax wax, which is about 10% contained in the bark layer of flax, has already been described in the literature. It is said to consist essentially of fatty acid esters; Long-chain alcohols and hydrocarbons exist (technology of textile fibers, "Der Flachs", volume V, 1,1,1930, 129 - 141 and 283; Hofmeister Ber. 1903, 1047; Ullmanns Enzyklopadie der Technische Chemie, 18th volume, 1967, 287 ). A material containing flax wax falls during the preparation of flax, in particular when kinking and swinging the roasted straw, when buckling green flax, when the shoring is carried out and also in other stages up to and including spinning into a more or less finely divided form. The coarse dust containing shafts and short tow parts contains flax wax in an amount of up to about 10% by weight and the fine and finest dust, such as is obtained in the spinning mill, in an amount of up to about 25% by weight. The flax wax can be extracted therefrom, for example in a continuous manner Solvents such as acetone, ethanol, benzene and subsequent stripping of the solvent can be obtained (GB-PS 630 274). Mixtures of the aforementioned dusts with smaller amounts of hemp dust can also be subjected to the extraction. A previous digestion of the flax waste with water and steam is known (DE-PS 817 335). It has now been found that products obtainable from flax wax have valuable properties. The present invention accordingly provides mixtures of substances of an oil-like consistency
  • a) by steam distillation of flax wax-containing raw material or from such raw material by solvent extraction and, if appropriate after the solvent has been removed, crude flax wax obtained and isolation of the specifically lighter phase, heavier phase and / or aqueous phase obtained in the steam distillation and the dewatering thereof or dewatering the mixture of phases.
  • b) by treatment of raw material containing flax wax or of raw raw material obtained from such raw material by solvent extraction, if necessary after stripping off the solvent, if necessary after the raw material or the raw flax wax beforehand were subjected to steam distillation, by means of aqueous acids, extraction of the then made alkaline aqueous solution with organic, polar solvents, in particular a boiling point up to about 80-85 ° C./96 kPa and obtaining therefrom the solvent-free extract or
  • c) by fractional distillation of flax-containing solutions in organic solvents to obtain the fraction of 90-150 ° C / 96 kPa.

Als flachswachshaltiges Rohmaterial kann z.B. das zuvor schon genannte, bei der Flachsaufbereitung, insbesondere beim Knicken und Schwingen des Röststrohs oder beim Grünflachsknicken,.bei der Verbaumwollung und auch noch in weiteren Stufen, wie dem Spinnen, anfallende mehr oder weniger feinteilige Material verwendet werden. Als Rohflachswachs kann das in bekannter Weise durch Extraktion gewonnene Flachswachs eingesetzt werden. Bevorzugt werden aber für die Extraktion, wegen der besseren Abtrennbarkeit, mit Wasser nicht mischbare, organische, polare Lösungsmittel, insbesondere Halogenkohlenwasserstoffe, wie 1,1,1-Trichloräthan, Methylenchlorid, Chloroform, Tetrachlorkohlenstoff benutzt, wenn auch Äthanol und Methanol sowie Ketone, wie Aceton, nicht ausgeschlossen sind. Ganz allgemein sind mit Wasser nicht mischbare, polare Lösungsmittel mit einem Siedepunkt von kleiner als etwa 80 - 85°C bevorzugt. Regelmäßig erfolgt die Gewinnung des Rohflachswachses aus diesen Lösungen durch Abdestillieren des Lösungsmittels, gegebenenfalls unter vermindertem Druck.As a raw material containing flax wax, the above-mentioned more or less fine material can be used, for example, in flax preparation, in particular when kinking and swinging the roasted straw or when folding green flax, in the case of shoring and in other stages, such as spinning. The flax wax obtained in a known manner by extraction can be used as raw flax wax. However, because of the better separability, water-immiscible, organic, polar solvents, in particular halogenated hydrocarbons, such as 1,1,1-trichloroethane, methylene chloride, chloroform, carbon tetrachloride, are preferably used for the extraction, although ethanol and methanol, and ketones, such as Acetone, are not excluded. In general, water-immiscible, polar solvents with a boiling point of less than about 80-85 ° C. are preferred. The raw flax wax is regularly obtained from these solutions by distilling off the solvent, if appropriate under reduced pressure.

Die Wasserdampfdestillation, insbesondere im Temperaturbereich um oder unter 100°C, vorzugsweise zwischen 95 und 100°C, sollte an einem neutralen bzw. schwach basischen Material, was gegebenenfalls durch entsprechende pH-Einstellung erfolgen kann, durchgeführt werden. Bei der Wasserdampfdestillation fallen in der Vorlage insgesamt drei Phasen an, nämlich eine obere (spezifisch leichtere), eine mittlere (wäßrige) und eine untere (spezifisch schwerere) Phase. Bevorzugt sind die Flachsöle der spezifisch schwersten, unteren Phase und die aus der darüber angeordneten wäßrigen Phase durch Entwässerung gewonnenen Flachsöle. Die Stoffe der oberen, spezifisch leichteren Phase riechen terpenartig. Weiter beinhaltet die Erfindung die aus diesen Phasen durch übliche Reinigung erhältlichen Konzentrate. Zu den Reinigungsverfahren gehören beispielsweise Adsorptionsmethoden, wie säulehchromatographische Behandlung, Destillationsmethoden, wie beispielsweise die Feindestillation, Extraktion der Phasen mit Lösungsmitteln, insbesondere der vorgenannten, und Gewinnung des lösungsmittelfreien Extrakts durch Destillation.The steam distillation, in particular in the temperature range around or below 100 ° C., preferably between 95 and 100 ° C., should be carried out on a neutral or weakly basic material, which can optionally be carried out by adjusting the pH accordingly. In the case of steam distillation, a total of three phases are produced, namely an upper (specifically lighter), a middle (aqueous) and a lower (specifically heavier) phase. The flat oils of the specifically heaviest, lower phase and the flat oils obtained from the aqueous phase arranged above them by dewatering are preferred. The substances in the upper, specifically lighter phase smell like terpenes. The invention further includes the concentrates obtainable from these phases by customary cleaning. The cleaning processes include, for example, adsorption methods, such as column chromatography treatment, distillation methods, such as, for example, fine distillation, phase extraction with solvents, in particular the aforementioned, and obtaining the solvent-free extract by distillation.

Für die Säureextraktion von flachswachshaltigem Rohmaterial oder Rohflachswachs empfehlen sich insbesondere verdünnte Mineralsäuren oder niedrige aliphatische Säuren, wie 0,1 - 1 n Salzsäure bzw. wäßrige Essigsäure. Für die Extraktion der durch Säurebehandlung, vorzugsweise von unlöslichen Bestandteilen befreiten und dann alkalisch, insbesondere pH 7,5 - 11, gemachten Lösung sind vor allem die gleichen Lösungsmittel geeignet, wie sie bei der Extraktion des Rohflachswachses aus flachswachshaltigem Rohmaterial zuvor schon genannt sind.Dilute mineral acids or low aliphatic acids, such as 0.1-1N hydrochloric acid or aqueous acetic acid, are particularly recommended for the acid extraction of raw material containing flax wax or raw flax wax. For the extraction of the solution made by acid treatment, preferably freed from insoluble components and then alkaline, in particular pH 7.5-11, the same solvents are particularly suitable as those previously mentioned for the extraction of the raw flax wax from raw material containing flax wax.

Der fraktionierten Destillation werden vorzugsweise flachswachshaltige Lösungen in wiederum solchen organischen Lösungsmitteln unterworfen, wie sie zuvor für die Gewinnung von Rohflachswachs bereits genannt sind, also mit einem Siedepunkt außerhalb etwa 90 - 150°C/96 kPa. Als Lösungsmittel kann beispielsweise auch Dibutylketon (Kp < 150°C) verwendet werden. Die Erfindung beinhaltet auch die durch übliche Reinigungs- und Trennungsverfahren isolierbaren Anteile. Zu solchen Verfahren gehören u.a. Adsorptionsverfahren, Feindestillation, Extraktionsverfahren, Ausfrieren usw.Fractional distillation is preferably subjected to solutions containing flax wax in organic solvents of the type already mentioned above for the production of raw flax wax, that is to say with a boiling point outside about 90-150 ° C./96 kPa. Dibutyl ketone (K p <150 ° C.), for example, can also be used as the solvent. The invention also includes the parts that can be isolated by conventional cleaning and separation processes. Such processes include, among others, adsorption processes, fine distillation, extraction processes, freezing out, etc.

Die erfindungsgemäß erhältlichen Stoffe zeichnen sich durch biologisch vorteilhafte Eigenschaften aus. So können sie in Salbengrundlagen zur Herstellung pharmazeutischer und kosmetischer Produkte verwendet werden. Sie wirken insbesondere im Sinne einer Förderung der Durchblutung und wirken schmerzlinderndbei Erkrankungen des rheumatischen Formenkreises, Muskelverspannungen und dergleichen. Sie können auch in Vitaminfeuchtigkeitscremes und -fetten verwendet werden. Auch als Zusätze zu Poliermitteln wie beispielsweise für Möbelpflegemittel, haben sie sich geeignet.The substances obtainable according to the invention are distinguished by their biologically advantageous properties. So they can be used in ointment bases for the manufacture of pharmaceutical and cosmetic products. They act in particular in the sense of promoting blood circulation and relieving pain in diseases of the rheumatic type, muscle tension and the like. They can also be used in vitamin moisturizers and fats. They are also suitable as additives to polishing agents such as furniture care products.
