Description
Lederfettungsmittel Gegenstand des Patents 896 697 sind Lederfettungsmittel mit einem, Gehalt an Stoffgemischen, welche durch teilweise Oxydation von -sehr hochmolekularen. a.liphatischen, praktisch gesättigten Kohlenwasserstoffenbis zu einer Säurezahl wesentlich unterhalb derjenigen, die sich unter Annahme einer Carboxyl.gruppe je Durchschnittsmolekül des Ausgang;sstoffes errechnet, erhalten werden.Leather fatliquor The subject of patent 896 697 is leather fatliquor with a content of mixtures of substances, which by partial oxidation of -very high molecular weight. a.liphatic, practically saturated hydrocarbons up to an acid number significantly below that which is calculated assuming one carboxyl group per average molecule of the starting material.
Es wurde nun gefunden, diaß man die mit solchen Enzeugn.issen hergestellten Lederfettungsmitteli noch verbessern, kann, wenn. man, ihnen Oxyd:at;ion@sprodukte von bei gewöhnlicher Temperatur flüssigen gesättigten oder teilweise ungesättigten höhermolekuliaren Kohlenwasserstoffen oder ihren Chlorierungspradukten zusetzt. Die Kohlenwasserstoffe können. z. B. durch Hydrieren von Kohlenoxyd erhalten. sein.It has now been found that one produced with such products Leather oiling agents can improve, if. man, them Oxyd: at; ion @ products of saturated or partially unsaturated ones that are liquid at ordinary temperature adding higher molecular hydrocarbons or their chlorination products. The hydrocarbons can. z. B. obtained by hydrogenation of carbon oxide. be.
Durch den Zusatz dieser Oxydationsprodukte erhält man Ledenfettungsmittel, die in dass Leder besonders leicht eindringen. Sie machen das Leder gut wasserabweisend und verleihen ihm einen vollen, geschmeidigen Griff.By adding these oxidation products, leather fat-giving agents are obtained, which penetrate the leather particularly easily. They make the leather well water repellent and give it a full, supple grip.
Beispiel i ioo kg abgeweliktes Fablleder werden. im Heiß-1u@ftifaß ibei 6o° mit ig kg eines I.ede:rfettu:ngsmi ttels gewalkt, das durch Zuisam,menschmelzen. von gleichen Teilen von Tran, @Degras und einer Mischung aus 25"/o eines bis zur Säurezahl, 4o oxydierten, hochschmelzenden Paraffins aus der Kohlenoxy.dhydrierung und 75% eines zwischen Zoo bis 35o° siedenden, bis zur Säurezahl 35 oxydierten Koh ,lenwasserstoffgemi.sches hergestellt wurde. Man erhält ein hochwertiges Fahlleder von. gutem Griff und guter Wasserabweisung, wie man es sonst nur durch entsprechenden Zusatz eines guten Talgs zur Fettschmiere erhält. Beispiele ioo kg abgewelktes Blankleder wenden ,mit einer Mischung .aus o,6 kg des im Bespiel i erwähnten Oxydationspro.dul,ts, von hochschmelzendem Paraffin (Säurezahl 4o), 2,4 kg eines bis zur Säurezahl 40 oxydierten Chlorierungsprodukts von flüssigen Paraffinen aus der Kohlenoxydhydrierung (Siede-Bereich 22o bis 32o°), i,4 kg Tran und i,6 kg Degras von Hand geschmiert. Dann walkt ,man es i Stunde im Heißluftfaß bei etiwa 55°. Man erhält ein im Griff, in der wasserahweisenden Wirkung und in allen sonstigen Eigenschaften einwandfreies Blankleder.Example ioo kg of worn-out leather will become. in the hot 1u @ ftifaß Ibei 60 ° with ig kg of an I.ede: rfettu: ngsmi ttels tumbled, that through Zuisam, human melting. of equal parts of Tran, @Degras and a mixture from 25 "/ o a high-melting paraffin from carbo-oxyhydrogenation, which is oxidized up to the acid number 4o and 75% of a Koh which boils between zoo and 35o ° and is oxidized to an acid number of 35 , Hydrogen Mixture was produced. A high quality pale leather is obtained from. good grip and good water repellency, as otherwise only possible with the appropriate Good sebum is added to the grease. Examples 100 kg of withered leather turn, with a mixture of 0.6 kg of the oxidation process mentioned in example i, of high-melting paraffin (acid number 4o), 2.4 kg of one up to acid number 40 oxidized chlorination product of liquid paraffins from carbohydrate hydrogenation (Boiling range 22o to 32o °), 1.4 kg of Tran and 1.6 kg of Degras lubricated by hand. Then you mill it for an hour in a hot air barrel at around 55 °. You get a grip Impeccable in the water-repellent effect and in all other properties Bare leather.
