Description

  

  Verfahren zur Herstellung eines Kondensationsproduktes.    Gegenstand des Hauptpatentes ist ein  Verfahren zur Herstellung eines Konden  sationsproduktes, das dadurch gekennzeichnet  ist, dass man ein durch Abbau von Eiweiss  substanzen erhaltenes     Peptidgemisch    mit dem  Gemisch der     Chlorkohlensäureester    des Alko  holgemisches, das durch Reduktion von Palm  kernfettsäure erhältlich ist, umsetzt.  



  Gegenstand vorliegenden Patentes ist nun  ein Verfahren zur Herstellung eines Konden  sationsproduktes, dadurch gekennzeichnet,  dass man ein gleiches     Peptidgemisch    mit dem       Chlorkohlensäureester    des     Oleylalkohols    um  setzt. Das so erhältliche Produkt kann bei  spielsweise als Netz-, Wasch- und     Disper-          giermittel    dienen und eignet sich insbesondere  als     Egalisiermittel    in der Färberei.  



  <I>Beispiel 1:</I>  Man schliesst 125 Teile Leim unter     Zu-          satz        von        20        cms        20%iger        Schwefelsäure    6  Stunden bei einer Temperatur von 115-1200    auf,

   neutralisiert mit Natronlauge und stellt       die        Reaktionsbrühe        auf        ca.        40        %        ein.        Dann     kondensiert man bei Zimmertemperatur mit  35 Teilen     Chlorkohlensäureester    des     Oleyl-          alkohols,    indem man durch Zugabe von  330%iger Natronlauge das Gemisch dauernd  schwach     triazenalkalisch    hält.     plan    rührt  2 Stunden bei 80-900 nach, dampft zur  Trockne und extrahiert das Reaktionsprodukt  mit Aceton.

   Der     acetonunlösliche    Rückstand  ist eine     bellbraun    gefärbte, krümelige Masse,  die sich in Wasser leicht zu klaren, gut  schäumenden Lösungen auflöst.    <I>Beispiel 2:</I>  Man schliesst 100 g Hautsubstanz mit       einem        Trockengehalt        von        70        %        mit        2,2        g     Kalk 12 Stunden bei 125-1300 auf,

   fällt  den Kalk mit Soda und stellt auf etwa       30        %        ige        Brühe        ein.        Diese        Brühe        kondensiert     man mit 60 g     Oleylchlorkohlensäureester,          indem        man        durch        Zugabe        von        33        %        iger         Natronlauge das Gemisch dauernd schwach       triazenalkalisch    hält.

   Die Aufarbeitung und  die Eigenschaften des erhaltenen, braun ge  färbten Produktes entsprechen den in Beispiel 1  angegebenen.



  Process for the production of a condensation product. The main patent relates to a process for producing a condensation product, which is characterized in that a peptide mixture obtained by breaking down protein substances is reacted with the mixture of chlorocarbonic acid esters of the alcohol mixture, which can be obtained by reducing palm kernel fatty acid.



  The present patent is now a process for the production of a condensation product, characterized in that an identical peptide mixture is implemented with the chlorocarbonic acid ester of oleyl alcohol. The product obtainable in this way can, for example, serve as a wetting agent, detergent and dispersant and is particularly suitable as a leveling agent in dyeing.



  <I> Example 1: </I> 125 parts of glue are digested with the addition of 20 cms of 20% sulfuric acid for 6 hours at a temperature of 115-1200,

   neutralized with sodium hydroxide solution and adjusts the reaction liquor to approx. 40%. The mixture is then condensed at room temperature with 35 parts of chlorocarbonate of oleyl alcohol by keeping the mixture permanently slightly alkaline with triazene by adding 330% strength sodium hydroxide solution. plan stirs for 2 hours at 80-900, evaporates to dryness and extracts the reaction product with acetone.

   The acetone-insoluble residue is a pale brown colored, crumbly mass which easily dissolves in water to give clear, well foaming solutions. <I> Example 2: </I> 100 g skin substance with a dry content of 70% is broken up with 2.2 g lime for 12 hours at 125-1300,

   drops the lime with soda and adjusts to about 30% broth. This broth is condensed with 60 g of oleylchlorocarbonic acid ester by keeping the mixture permanently slightly alkaline with triazene by adding 33% strength sodium hydroxide solution.

   The work-up and the properties of the brown colored product obtained correspond to those given in Example 1.
