Description

Verfahren zur Herstellung von Furfurolseifen. Für das Furfurol, welches in erheblichen Mengen bei der Zellstoff- und Futtermittelfabrikation gewonnen werden kann, hat man bisher keine geeignete Verwendung gefunden. Es hat sich nun gezeigt, daß man das an sich in Wasser schwer lösliche Furfurol in Seifenlösungen (Kali- sowie Natron- und auch Harzseifen) auflösen kann. Es ist überraschend, daß diese alkalischen Präparate sich beim Aufbewahren nicht verändern, während Furfurol eine sehr alkaliempfindliche Substanz ist, indem es nicht nur wie andere aromatische Aldehyde der Umbildung in Säure und Alkoliol durch Alkali unterliegt, sondern fernerhin die besondere Eigentümlichkeit besitzt, unter dem Einfluß schon geringer Alkalimengen zu verharzen.Process for the production of furfural soaps. For the furfural which are obtained in considerable quantities in the manufacture of pulp and animal feed no suitable use has yet been found. It has now been shown that furfural, which in itself is sparingly soluble in water, can be dissolved in soap solutions (potash as well as soda and resin soaps). It is surprising that this alkaline preparations do not change when stored, while furfurol is a very alkali-sensitive substance is by being not only aromatic like other Aldehydes are subject to conversion into acid and alkoliol by alkali, but continue to do so has a special peculiarity under the influence of even small amounts of alkali to resinify.

Der flüssigen Furfurolseife kann man eine Furfurolkonzentration erteilen, die ein Vielfaches der Löslichkeit des Furfurols in Wasser beträgt. Man erhält z. D. ein solches Furfurolpräparat mit 18 Prozent Furfurolgehalt, wenn 41 Gewichtsteile einer 25 prözentigen Leinöl-Harz-Kaliseife (die noch schmierseifenartige Konsistenz besitzt) mit 9 Gewichtsteilen Furfurol in der Hitze vermischt werden. Dieser Vorgang ist auf eine L ösungsaffinität des Furfurols zur Seife zurückzuführen, während nach allen bisherigen Erfahrungen aromatische Aldehyde in ihrer Löslichkeit von gewöhnlichen Seifenlösungen ` nicht beeinflußt werden.The liquid furfural soap can be given a furfural concentration, which is a multiple of the solubility of furfural in water. One obtains z. D. such a furfural preparation with 18 percent furfural content if 41 parts by weight a 25 percent linseed oil resin potash soap (the still slippery soap-like consistency owns) are mixed with 9 parts by weight of furfural in the heat. This process is due to a solution affinity of furfural for soap, while after all previous experiences aromatic aldehydes in their solubility from ordinary ones Soapy solutions `are not affected.

Feste Furfurolseifen kann man einerseits herstellen, indem man heißen konzentrierten Natronseifenlösungen Furfurol hinzufügt; wobei man beim Erkalten in bekannter Weise Leimseifen bzw. Halbkernseifen erhält, oder indem man anderseits Seifenspäne unter Zusatz von Furfurol piliert, da es sich gezeigt hat, daß erwärmte Seifenspäne Furfurol gut ..aufsaugen.Solid furfural soaps can be produced on the one hand by being called adding furfurol to concentrated soda soap solutions; whereby one when cooling down in a known manner, glue soaps or semi-core soaps are obtained, or by doing the other hand Soap shavings with the addition of furfural piled, since it has been shown that warmed Soak up Furfurol soap shavings well.

Die nach dem vorliegenden Verfahren hergestellten Produkte lassen sich als Desinfektionsmittel verwenden, da die bakteriologische Prüfung ergeben hat, daß Furfurol ein praktisches, seifenfestes Desinfektionsmittel ist. Gegenüber den bekannten Desinfektionsmitteln ähnlicher Zusammensetzung, insbesonders gegenüber Kresolseifen, zeichnen sich die Furfurolseifen durch ihre Salzbeständigkeit aus, was sowohl bei der Herstellung wie bei der Anwendung von Bedeutung ist.Leave the products made according to the present process Use as a disinfectant, as the bacteriological test reveal has that furfural is a practical, soap-proof disinfectant. Opposite to the known disinfectants of similar composition, especially compared to Cresol soaps, the furfural soaps are characterized by their salt resistance, which is important both in production and in use.

Furfurolseifen eignen sich ferner als Textilseifen, da sie Mineralöl sowie Chlormethanclerivate emulgieren und der übrigens angenehme Furfurolgeruch sich in den Textilwaren nicht verfängt, sondern rasch verfliegt. Schließlich können Furfurolseifen unter Zusatz eines geringen Überschusses an verdünntem Alkalihydroxyd als Lösungsmit tel eingetrockneter Lacke und Anstriche verwendet werden.Furfural soaps are also suitable as textile soaps because they are mineral oil as well as chloromethane derivatives emulsify and the incidentally pleasant furfural smell does not get caught in the textile goods, but dissipates quickly. Finally you can Furfural soaps with the addition of a small excess of dilute alkali hydroxide as a solution tel dried varnishes and paints are used will.
