    . Verfahren   zur Erzielung eines dauerhaften, ergiebigen und durch Zusätze bekannter Art in der konservierenden Kraft verstärkten Belages von Benzoesäure auf Papier. 



   Im nachfolgendem wird ein Verfahren beschrieben, welches in erster Linie darauf abzielt, Benzoesäure in deren Anwendung als Konservierungsstoff besser und in grösseren Mengen an Papier binden zu können, als dies durch einfache Lösung dieser Säure in Wasser oder AlkoholGlyzeringemischen erreichbar wäre. Benzoesäure ist einerseits in solchen Lösungsmittel nur in Mengen löslich, welche bloss einen unzureichenden Niederschlag der Säure am Papiere ermöglichen, andrerseits haftet die Säure nach dem Verdunsten des Lösungsmittels so lose am Papiere an, dass dieselbe leicht abstäubt. Diesem Nachteile wirkt die Umwandlung der Säure in ein Benzoesäureglyzerid entgegen, welches erhalten wird, wenn man 100 Gewichtsteile Glyzerin auf   go0 C   erwärmt und 24 bis 92 Gewichtsteile Benzoesäure einträgt.

   Das hierdurch entstehende, ölige Produkt erstarrt zu einer festen Masse von kristallischem Gefüge, welche bei goo wieder schmilzt. Dem flüssigen Glyzeride werden noch die konservierende Kraft verstärkende, weiters den Geschmack verändernde Zusätze bekannter Art, wie Parachlorbenzoesaures Natron, Kochsalz, Essigsäure u.   dgl.,   beigegeben. Ein Ausführungsbeispiel enthält 48 Gewichtsprozent Benzoesäure und einen Zusatz von Essigsäure. Das Glyzerid wird in flüssigem Zustande oder in einem geeigneten Lösungsmittel, wie Alkohol, gelöst, am Papiere aufgetragen, wodurch ein gleichartiger, gut anhaftender Überzug, dessen Stärke beliebig gewählt werden kann, am Papiere entsteht.

    . Process for achieving a permanent, high-yield coating of benzoic acid on paper that is reinforced by additives of a known type in the preservative power.



   In the following, a method is described which primarily aims to be able to bind benzoic acid to paper better and in larger quantities when used as a preservative than could be achieved by simply dissolving this acid in water or alcohol-glycerine mixtures. On the one hand, benzoic acid is only soluble in such solvents in quantities that only allow insufficient precipitation of the acid on the paper, on the other hand, after the solvent has evaporated, the acid adheres so loosely to the paper that it easily dusts off. This disadvantage is counteracted by the conversion of the acid into a benzoic acid glyceride, which is obtained when 100 parts by weight of glycerol are heated to go0 ° C. and 24 to 92 parts by weight of benzoic acid are introduced.

   The resulting oily product solidifies to a solid mass of crystalline structure, which melts again with goo. The liquid glyceride contains additives of known types, such as sodium parachlorobenzoate, table salt, acetic acid and the like, which increase the preservative power and also change the taste. Like., added. One embodiment contains 48 percent by weight of benzoic acid and an addition of acetic acid. The glyceride is applied to the paper in a liquid state or dissolved in a suitable solvent such as alcohol, whereby a similar, well-adhering coating, the thickness of which can be selected as desired, is created on the paper.
