Description

Verfahren zur Herstellung von Dispergier-, Netz- und Reinigungsmitteln Es ist an sich bekannt, daß die bei der Sulfitzelluloseherstellung .anfallende Ablauge, die als Sulfitablauge bekannt ist und in der Hauptsache aus Ligninsulfonsäure besteht, dispergierende und schutzkolloide Eigenschaften besitzt und beim Färben von Textilien als Schutzkolloid verwendet «-erden kann. Ein großer Nachteil für ihre ausgedehnte Verwendung ist jedoch die dunkle Farbe der Sulfitablaugen, welche ihre Verwendung in verschiedenen Prozessen der Textilveredelung ausschließt, und der vollkommene Mangel an Netz-und Reinigungswirkung.Process for the production of dispersants, wetting agents and cleaning agents It is known per se that the waste liquor obtained in the production of sulphite cellulose, which is known as sulphite waste liquor and consists mainly of lignosulphonic acid, Has dispersing and protective colloid properties and when dyeing textiles used as a protective colloid. A big disadvantage for her extended However, the dark color of the sulphite waste liquors is what their use is used for excludes in various processes of textile finishing, and the perfect one Lack of wetting and cleaning action.

Es wurde nun, gefunden, daß die Di-spergierfähigkeit von Sulfitzelluloseablaugen wesentlich gesteigert werden kann und außerdem Produkte mit Netz- und Reinigungswirkung erhalten werden, wenn sie mit Verbindungen, welche die Gruppen Alkyl-, Alkylaryl-, Aryl-, Aralkyl-, Acyl-, besonders sulfonsäuregruppenhaltige Verbindungen enthalten, kondensiert werden. Am vorteilhaftesten hat sich die Einführung von Sulfonsäureresten erwiesen, welche mit Hilfe von deren Chloriden leicht erfolgen kann. Ein Zusatz wasserlöslicher Alkohole beschleunigt die Kondensation.It has now been found that the dispersibility of sulphite cellulose waste liquors can be increased significantly and also products with a wetting and cleaning effect are obtained when they are combined with compounds containing the groups alkyl, alkylaryl, Contain aryl, aralkyl, acyl, especially sulfonic acid group-containing compounds, be condensed. The introduction of sulfonic acid residues has proven to be most beneficial proven, which can easily be done with the help of their chlorides. An addition water-soluble alcohols accelerate condensation.

Diese Produkte besitzen gegenüber dem Ausgangsstoff ein gesteigertes Dispergiervermögen, haben außerdem Netz- und Reinigungswirkung und können beim Färben, Bleichen und Waschen von Fasergut Verwendung finden. Ein wesentlicher Vorteil dieser Kondensationsprodukte ist außerdem ihre Bleichfähigkeit, wodurch sie im Gegensatz zum Ausgangsmaterial (Sulfitablauge) stehen. Die hellen Produkte, die hierbei gewonnen werden, können bei den verschiedensten Textilveredlungsprozessen mit Vorteil angewendet werden, wo es auf Dispergieren, Netzen und Reinigen ankommt.These products have a higher quality than the starting material Dispersing power, also have a wetting and cleaning effect and can be used during dyeing, Find bleaching and washing of fiber material use. A major benefit of this Condensation products is also their bleaching ability, which makes them unlike to the starting material (sulphite waste liquor). The bright products obtained here can be used in a wide variety of textile finishing processes with Advantageously, wherever dispersing, wetting and cleaning are important.

Beispiel z 2oo kg Sulfitablauge mit einem Gehalt von 5o% ligninsulfonsaurem Natrium werden bei einer Temperatur von 5o bis 6o° mit etwa $o kg eines durch Sulfochlorierung von Kogasin mittels eines Schwefeldioxyd-Chlor-Gemisches erhältlichen Alkylsulfönsäurechlonides unter Zusatz von Ätzalkalrien kondensiert. Nach Beendigung der Reaktion wird verdünnt und das Unverseifbare getrennt. Das Reaktionsprodukt ist eine leicht viskose Flüssigkeit, die als solche verwendet werden kann.Example z 2oo kg of sulphite waste liquor with a content of 50% lignosulphonic acid Sodium are at a temperature of 50 to 6o ° with about $ o kg of one by sulfochlorination Alkylsulfönäurchlonides obtainable from Kogasin by means of a sulfur dioxide-chlorine mixture condensed with the addition of caustic alkalis. After the reaction has ended, it is diluted and the unsaponifiable separately. The reaction product is a slightly viscous liquid, which can be used as such.

Beispie12 Das nach Beispiel r erhaltene Kondensationsprodukt wird mit 2 bis, 3 % H2 02 stufenweise unter Erwärmen behandelt, wodurch man ein gelbbraunes Produkt erhält. Werden die nicht in Reaktion getretenen Anteile der Zellstoffablauge vorher durch Aussalzen abgetrennt, so erhält man ein noch helleres Produkt.Beispie12 The condensation product obtained according to Example r is with 2 to, 3% H2 02 gradually treated with heating, whereby a yellow-brown Product received. Are the unreacted portions of the pulp waste liquor previously separated by salting out, an even lighter product is obtained.
