Description
Mittel gegen Schaumbildung Bei der Verarbeitung wäßriger kolloider Lösungen, beispielsweise von Leim, Gelatine, Casein, Blutalbumin und anderen Eiweißstoffen, ferner von Seifen und manchen organischen Farbstoffen sowie von bei der Vergärung kohlenhydrathaltiger Stoffe erhaltenen Schlempen u. dgl., wirkt die Schaumbildung äußerst störend. Dies gilt auch für manche unter Gasentwicklung oder unter Hindurchleiten von Gasen durch Flüssigkeiten verlaufende chemische Prozesse.Anti-foaming agent when processing aqueous colloids Solutions, for example of glue, gelatine, casein, blood albumin and other proteins, also from soaps and some organic dyes as well as from fermentation Schlempen and the like obtained from carbohydrate-containing substances, the foaming takes place extremely annoying. This also applies to some with evolution of gas or with passing through Chemical processes moving gases through liquids.
Demgegenüber wurde gefunden, daß sich diese Schaumbildung durch einen Zusatz äußerst geringer Mengen von höhermolekularen aliphatischen zweiwertigen Alkoholen, derea Hydroxylgruppen an benachbarten Içoh lenstoffatomen stehen, so gut wie völlig vermelden läßt. In contrast, it was found that this foam formation by a Addition of extremely small amounts of higher molecular weight aliphatic dihydric alcohols, there are almost all of the hydroxyl groups on neighboring carbon atoms lets report.
Höhermolekulare aliphatische zweiwertige Alkohole der genannten Art werden beispiels weise aus mindestens 8 Kohlenstoffatome enthaltenden Monoolefinen durch Oxydation vermittels Luft in Gegenwart von Säure oder durch Anlagerung von Halogenen mit nachfolgender Verseifung der entstandenen Mineralsäureester oder durch Anlagerung von Wasserstoffperoxyd erhalten. Higher molecular weight aliphatic dihydric alcohols of the type mentioned are example, from monoolefins containing at least 8 carbon atoms by oxidation by means of air in the presence of acid or by the addition of Halogens with subsequent saponification of the resulting mineral acid esters or by Accumulation of hydrogen peroxide obtained.
Beispiele 1. Einer 10%igen Lösung von Knochenleim in L:eitungswasser (12° D. H.) wird 1% (berechnet auf Trockensubstanz) eines Diolgemisches (OH-Zahl 395), dessen Bestandteile 13 bis 17 Kohlenstoffatome aufweisen (erhalten durch Ketonisierung synthetischer Fettsäuren aus der Paraffinoxydation, sog. Vor lauffettsäuren, mit nachfolgender Reduktion zu den entsprechenden sekundären Alkoholen, Dehydratisierung der letzteren zu den Olefinen und Oxydation der Olefine mit Luft in Gegenwart von Säure zu den Diolen), zugesetzt. Man erhält eine bei 45° nicht mehr schäumende Leimlösung. Examples 1. A 10% solution of bone glue in tap water (12 ° D.H.) is 1% (calculated on dry matter) of a diol mixture (OH number 395), the components of which have 13 to 17 carbon atoms (obtained by ketonization synthetic fatty acids from paraffin oxidation, so-called pre-run fatty acids, with subsequent reduction to the corresponding secondary alcohols, dehydration the latter to the olefins and oxidation of the olefins with air in the presence of Acid to the diols), added. A glue solution which no longer foams at 45 ° is obtained.
10 cm5 der Leimlösung mit und ohne Diolzusatz werden mit der Hand
geschüttelt und die Schaumhöhe in Millimetern gemessen.
3. Einer Fischeiweißlösung in Leitungswasser (25 g!l) wird 1010 (berechnet auf die Trockensubstanz) 1, 2-Dioxyoctadecan (OH# Zahl 351, CO-Zahl 8) zugesetzt. Man erhält eine nicht schäumende Lösung. 3. A fish protein solution in tap water (25 g! L) is 1010 (calculated on the dry substance) 1,2-Dioxyoctadecane (OH number 351, CO number 8) was added. A non-foaming solution is obtained.
10 cms der Fischeiweißlösung werden mit der Hand geschüttelt, worauf
die Schaumhöhe in Millimetern gemessen wird.
