Description
DEUTSCHESGERMAN
Gegenstand der Erfindung ist die Verwendung von Pyrokohlensäureestern als Konservierungsmittel für verderbliche Stoffe. Die Pyrokohlensäureester entsprechen der allgemeinen FormelThe invention relates to the use of pyrocarbonic acid esters as preservatives for perishable products Fabrics. The pyrocarbonic acid esters correspond to the general formula
R—O—C—O—C—O—RR — O — C — O — C — O — R
in denen die beiden R gleiche oder verschiedene organisehe Reste bedeuten; solche Reste sind beispielsweise Alkylreste, wie Methyl, Äthyl, Propyl, Isopropyl, Butyl, Isobutyl, Amyl und Isoamyl, oder Cycloalkylreste, wie Cyclohexyl, ferner Aryl- oder Aralkylreste, wie Phenyl und Benzyl, oder auch heterocyclische Reste, wie z. B. Furfuryl.in which the two R's are the same or different Mean residues; such radicals are, for example, alkyl radicals, such as methyl, ethyl, propyl, isopropyl, butyl, Isobutyl, amyl and isoamyl, or cycloalkyl radicals such as cyclohexyl, and also aryl or aralkyl radicals such as phenyl and benzyl, or heterocyclic radicals, such as. B. furfuryl.
Die erfindungsgemäß als Konservierungsmittel zu verwendenden Pyrokohlensäureester können auf verschiedene Weise hergestellt worden sein, z. B. durch Umsetzung von Chlorameisensäureestern mit Alkalisalzen von Kohlensäurehalbestern.The pyrocarbonic acid esters to be used as preservatives according to the invention can have various properties Way have been made, e.g. B. by reacting chloroformic acid esters with alkali salts of Carbonated half-esters.
Die Anwendung der vorgeschlagenen Konservierungsmittel erfolgt in an sich bekannter Weise: man setzt die Mittel als solche oder in Form einer Lösung bzw. Dispersion in geeigneten Medien, z. B. in Form einer frisch bereiteten wäßrigen Dispersion, den zu konservierenden Stoffen zu, vermischt sie erforderlichenfalls innig mit den Stoffen und sorgt dafür, daß die Stoffe dann zweckmäßig verschlossen bzw. verpackt werden.The proposed preservatives are used in a manner known per se: the Agents as such or in the form of a solution or dispersion in suitable media, e.g. B. in the form of a fresh prepared aqueous dispersion, the substances to be preserved, mixed them intimately if necessary the substances and ensures that the substances are then appropriately sealed or packaged.
Die erforderlichen Mengen an den Konservierungsmitteln lassen sich von Fall zu Fall durch Vorversuche leicht ermitteln; im allgemeinen genügen Mengen von etwa 0,01 bis 2 0J0, bezogen auf die Menge des zu konservierenden Stoffes.The required amounts of preservatives can easily be determined from case to case by preliminary tests; In general, amounts of about 0.01 to 2 0 I 0 , based on the amount of the substance to be preserved, are sufficient.
Mit den vorgeschlagenen Mitteln ist es möglich, verderbliche Stoffe vegetabilischer oder animalischer Her-Konservierungsmittel With the proposed means it is possible to use perishable substances from vegetable or animal preservatives

kunft in vorteilhafter Weise zu konservieren. Zu den Stoffen, die erfindungsgemäß konserviert werden können, gehören insbesondere Kohlehydrate enthaltende Stoffe, wie z. B. Gemüsesorten der verschiedensten Art, Fruchtmark, Fruchtextrakte oder -safte und Drogenextrakte, ferner Kasein und andere proteinhaltige Stoffe sowie Injektionslösungen und andere pharmazeutische oder kosmetische Zubereitungen verderblicher Art. Die Mittel lassen sich auch bei sogenannten biologischen Konservierungsverfahren, z. B. bei der Silierung, vorteilhaft verwenden ; man kann auf diese Weise oftmals unerwünschte Gärungsvorgänge, etwa eine Buttersäuregärung, ganz oder für eine gewisse Zeit verhindern.to preserve the future in an advantageous manner. Among the substances that can be preserved according to the invention, include in particular substances containing carbohydrates, such as. B. Various kinds of vegetables, fruit pulp, Fruit extracts or juices and drug extracts, as well as casein and other protein-containing substances as well Injection solutions and other perishable pharmaceutical or cosmetic preparations. The means can also be used in so-called biological preservation processes, e.g. B. in ensiling, use advantageous ; In this way, undesired fermentation processes, such as butyric acid fermentation, can often be completely eliminated or prevent it for a period of time.
Es hat sich erwiesen, daß die Pyrokohlensäureester bei ihrem Einsatz als Konservierungsmittel mit Verbindungen, die aktive Wasserstoffatome enthalten, und in Gegenwart von Wasser innerhalb weniger Stunden quantitativ nach der GleichungIt has been shown that the pyrocarbonic acid esters when used as preservatives with compounds which contain active hydrogen atoms, and in the presence of water within a few hours quantitatively according to the equation

(X = Rest einer aktiven Wasserstoff enthaltenden Verbindung) reagieren. Wie hieraus ersichtlich ist, setzen sich die Ester bei ihrer Wirkungsentfaltung irreversibel um. Die Konservierung hält infolgedessen nur so lange vor, wie geeignete Verschlüsse oder Verpackungen eine Neuinfizierung verhindern. Andererseits sind die erfindungsgemäß konservierten Stoffe nach Öffnen des Verschlusses oder der Verpackung wieder fermentativen Prozessen zugänglich, was für die Verträglichkeit zur Verdauung gelangender Stoffe von großer Bedeutung ist.(X = residue of an active hydrogen-containing compound) react. As can be seen from this, set the esters are irreversibly reversed when they are active. As a result, the preservation only lasts that long suggests how suitable closures or packaging prevent re-infection. On the other hand, they are according to the invention Preserved substances are fermentative again after opening the closure or the packaging Processes accessible, which is of great importance for the tolerance of the digestive substances.
Von den Pyrokohlensäureestern verdient der Diäthylester im allgemeinen den Vorzug, da die hieraus entstehenden Umsetzungsprodukte physiologisch unbedenklich sind; handelt es sich in diesem Falle doch in der Hauptsache um Kohlensäure und Äthylalkohol, d. h. also um Stoffe, die auch natürliche Stoffwechselprodukte von Gärhefen sind.Of the pyrocarbonic acid esters, the diethyl ester generally deserves preference, since those resulting therefrom Reaction products are physiologically harmless; In this case it is the main thing about carbonic acid and ethyl alcohol, d. H. in other words, substances that are also natural metabolites of fermentation yeast are.
Gegenüber der bekannten Sterilisation von verderblichen Stoffen durch Hitzebehandlung weisen die erfindungsgemäß zu verwendenden Konservierungsmittel denCompared to the known sterilization of perishable substances by heat treatment, the invention the preservative to be used
