Description
Patentiert im Deutschen Reiche vom 9. Oktober 1921 ab. Es ist bekannt, daß man durch Mischen von Steinkohlenteerölen mit Fettsäure-, Harzsäure- oder auch Naphthensäureseifen Desinfektionsmittel erhält, die mit Wasser be- ständige Emulsionen liefern. Diese Teeröle fallen bei der Destillation des Steinkohlenteers unmittelbar an.Patented in the German Empire on October 9, 1921 . It is known that receives disinfectant by mixing coal tar oils with fatty acid, rosin acid or Naphthensäureseifen that provide constant loading with water emulsions. These tar oils are obtained directly when the coal tar is distilled.
Es enthält aber auch der Braunkohlenteer desinfektorisch wertvolle Teeröle, sogenannte Kreosotöle. Diese werden nicht unmittelbar durch Destillation des Teers gewonnen, vielmehr muß diesermitAlkaliausgelaugtwerden, und die Lauge muß dann zur Gewinnung der freien Kreosote erst mit Säure zersetzt werden. Braunkohlenteerkreosot hat als Bestandteil von seifenhaltigen Desinfektionsmitteln bisher keine Anwendung gefunden, es wurde lediglich in Gemisch mit Steinkohlenteerölen zur Imprägnierung von Holz verwendet, wenn nicht überhaupt nur zu Heizzwecken.But it also contains lignite tar that is valuable for disinfection Tar oils, so-called creosote oils. These are not made directly by distillation obtained from the tar, rather this must be leached with alkali, and the lye must then first be decomposed with acid in order to obtain the free creosote. Lignite tar creosote has not been used as a component of soap-based disinfectants found, it was only used in a mixture with coal tar oils for impregnation of wood used, if not only for heating purposes at all.
Es wurde nun gefunden, daß man die aus dem Braunkohlenteer ursprünglich anfallenden Kreosotlaugen unmittelbar, ohne vorherige Abscheidung der Kreosote durch Säure, zur Herstellung von wertvollen Desinfektionsmitteln verwenden kann, wenn man sie mit Naphthensäure neutralisiert. Hierbei werden Flüssigkeiten erhalten, die bei der Verdünnung mit Wasser beständige Emulsionen liefern und ohne weiteres als hochwertige Desinfektionsmittel verwendbar sind. Es beruht das darauf, daß die Natriumsalze der Naphthensäure im Gegensatz zu denen der Fett- und Harzsäuren schmierseifenähnliche Eigenschaften besitzen. Nimmt man die Neutralisation der freien Braunkolilenteerkreosotlaugen mit Harzsäure oder mit Fettsäure vor, so erhält man mehr oder weniger zähe, nicht gießbare Gemische, welche sich zur Herstellung desinfizierender Emulsionen nicht eignen.It has now been found that those from the lignite tar were originally accruing creosote liquor immediately, without prior separation of the creosote Acid, can be used to produce valuable disinfectants, though they are neutralized with naphthenic acid. Liquids are obtained here, which when diluted with water provide stable emulsions and easily can be used as high-quality disinfectants. It is based on the fact that the Sodium salts of naphthenic acid in contrast to those of fatty and resin acids similar to soft soap Possess properties. If one takes the neutralization of the free brown coal tar creosote liquor with resin acid or with fatty acid, more or less tough ones are not obtained Pourable mixtures, which are not suitable for the production of disinfecting emulsions suitable.
An Stelle der gewöhnlichen Naphthensäuren kann man zum Absättigen der Laugen auch sulfurierte Naphthensäure verwenden, deren Salze ein höheres Ernulgierungsvermögen als die der nicht sulflerten Naphthensäure haben. B eispiel.Instead of the usual naphthenic acids, it can be used for saturation of alkalis also use sulfurized naphthenic acid, the salts of which have a higher emulsifying power than that of non-sulphurised naphthenic acid. Example.
5oo Teile Braunkohlenteerkreosotlauge werden mit der zur Neutralisation notwendigen Menge Naphthensäure oderNaphthensulfosäure und so viel Wasser versetzt, daß der Gehalt der Mischung an Kreosoten etwa 30 Prozent beträgt.500 parts of lignite tar creosote liquor are mixed with the amount of naphthenic acid or naphthene sulfonic acid necessary for neutralization and enough water that the creosote content of the mixture is about 30 percent.
# Die Darstellung von Desinfektionsmitteln durch Mischen von Kohlenteerkreosot mit naphthensaurem Ammonium ist bekannt. Dabei wird eine weißgraue Emulsion erhalten, und es findet kein Neutralisieren von Kreosotlauge mit Naphthensäure statt; ferner handelt es sich dort ausschließlich um Steinkohlenteerkreosot, wie aus der für dieses charakteristischen weißgrauen Farbe der Emulsion hervorgeht. Zudem liegt hier bereits eine Emulsion vor, während die nacli dem vorliegenden Verfahren hergestellten Erzeugnisse dunkle gleichförmige Flüssigkeiten darstellen, die erst beim Verdünnen mit Wasser Emulsionen liefern. Steinkohlenteerkreosotlaugeist, wie Versuche gezeigt haben, nicht geeignet, mit Naphthensäure brauchbare DesinfektionsmitLel zuliefern, dadieaussolchenMischungen hergestellten Emulsionen wenig beständig sind. Es beruht dieg auf der geringeren Viskosität der Kohlenwasserstoffe des Steinkolilenteerkreosots gegenüber denen des Braunkohlenteerkreosos. Zudem b,-s*tzen die aus Braunkohlenteerkreosot hergestellten Desinfektionsmi-,tel infolge ihres höheren Gehaltes an mehrwertigen Plienolen bei sonst gleicher Zusammensetzung eine größere Desinfektionskraft als die aus Steinkohlenteerkreosot hergestellten-# The presentation of disinfectants by mixing coal tar creosote with ammonium naphthenic acid is known. A white-gray emulsion is obtained, and there is no neutralization of creosote liquor with naphthenic acid; further it is exclusively coal tar creosote, like the one for this one characteristic white-gray color of the emulsion. In addition, here is already an emulsion before, while the products manufactured according to the present process represent dark, uniform liquids that only appear when diluted with water Deliver emulsions. Coal tar creosote liquor, like attempts have shown that disinfectants that can be used with naphthenic acid are not suitable because the emulsions produced from such mixtures are not very stable. It is based on the lower viscosity of the hydrocarbons in stone colil tar creosote compared to those of the lignite tar creos. In addition, those made from lignite tar creosote manufactured disinfectants due to their higher content of polyvalent Plienols with otherwise the same composition have a greater disinfectant power than those made from coal tar creosote
