Es wurde gefunden, daß man die Möglichkeit der Abscheidung schwer filtrierbarer Stoffe aus wäßrigen Flüssigkeiten, insbesondere ihre Filtrierfähigkeit, dadurch günstig beeinflussen, kann, daß man die Flüssigkeiten mit geringen Mengen höhermolekularer Fettsäureester oder Fettsäureamide, die im aliphatischen Ester- oder Amidrest durch eine endständige Sulfogruppe substituiert sind, versetzt.It has been found that the possibility of separation is difficult to filter Substances from aqueous liquids, especially their filterability, are therefore beneficial can influence the fact that the liquids with small amounts of higher molecular weight fatty acid esters or fatty acid amides in the aliphatic ester or amide radical by a terminal Sulfo group are substituted, added. Solche Körper sind beispielsweise in den britischen Patentschriften 366916, 367585 und 372 005 beschrieben. Danach sind als Zusatzstoffe z. B. verwendbar die Veresterunigsprodukte höherer Fettsäuren mit Oxy-Such bodies are for example in British patents 366916, 367585 and 372 005. Thereafter, as additives such. B. usable the Veresterunigsprodukte higher fatty acids with oxy- J5 alkylsulfosäure, z. B. Oxäthansulfosäure, Oxypropansulfosäure, oder die Umsetzungsprodukte höherer Fettsäuren mit Aminosulfosäuren vom Typus des Taurins oder substituierten Taurins, z. B. einer Aminooxyalkylsulfosäure, wie a-Amino-ß-Oxypropansulfosäure usw.J5 alkyl sulfonic acid, e.g. B. oxethanesulfonic acid, oxypropanesulfonic acid, or the reaction products of higher fatty acids with aminosulfonic acids of the taurine type or substituted Taurines, e.g. B. an aminooxyalkylsulfonic acid, such as α-amino-ß-oxypropanesulfonic acid etc. Die als Zusatz in Frage kommenden relativ geringen Mengen vorgenannter Stoffe können sich in ziemlich weiten Grenzen bewegen.The relatively small amounts of the aforementioned substances which can be used as additives move within fairly wide limits. Einem mengenmäßig zu hohen Zusatz ist dadurch eine Grenze gesetzt, daß bei Zusatz größerer Mengen die bekannte Dispergierwirkung vorgenannter Stoffe zur Geltung kommt und somit die umgekehrte Wirkung erreicht wird.There is a limit to an excessively high amount of additive larger amounts the known dispersing effect of the aforementioned substances comes into play and thus the opposite effect is achieved. Es war überraschend und neuartig, daß bei Anwendung geringer Mengen der Zusatzstoffe eine vorteilhafte Beeinflussung der FiI-trierfähigkeit eintritt. Die Wirkung ist sowohl in neutralen als auch in sauren oder alkalischen Flüssigkeiten vorhanden. Es tritt keine Erhöhung der Viscosität der Flüssigkeiten ein, was auch schon daraus hervorgeht, daß die als Zusatz verwendeten Produkte mehr oder weniger molekulardispersen Charakter besitzen.It was surprising and novel that when using small amounts of the additives an advantageous influence on the filtering ability entry. The effect is in neutral as well as in acidic or alkaline liquids present. There is no increase in the viscosity of the liquids a, which is also evident from the fact that the products used as additives are more or less molecularly disperse Have character. Bei spielExample 5 g Tonerdehydrat, die in nicht mehr filtrierbarer feinster Form in 11 Wasser verteilt sind, werden mit 0,07 g eines Produktes versetzt, welches erhalten ist durch Umsetzung von Ölsäurechlorid mit oxäthansulfosaurem Natrium. Das Tonerdehydrat flockt sogleich aus und läßt sich leicht filtrieren.5 g of alumina hydrate, which is distributed in 11 water in the finest form that can no longer be filtered are, are mixed with 0.07 g of a product which is obtained by reaction of oleic acid chloride with sodium oxäthansulfosaurem. The alumina hydrate flocculates immediately and can be easily filtered.
