Description

  

  Verfahren zur Darstellung eines Kondensationsproduktes.    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines Konden  sationsproduktes, dadurch gekennzeichnet, dass  man     3,5-Di(chlormethyl)-2-oxy-benzoesäure     mit 2     Mol.        2-Octadecylaminobenzoesäure    um  setzt. Die neue Verbindung bildet als Natrium  salz ein in Wasser klar lösliches, bräunliches  Pulver mit stark     subatantiven    Eigenschaften.  Sie eignet sich als     Weichmachungsmittel    für  Kunstseiden aller Art und kann gleichzeitig  mit Direktfarbstoffen im Färbebad verwendet  werden.  



  <I>Beispiel:</I>  76 Teile     2-Octadecylaminobenzoesäure     werden in 350 Teilen Chlorbenzol gelöst und  41,3 Teile     3,5-Di(chlormethyl)-2-oxy-benzoe-          säure    71,5     %ig    dazu gegeben. Man erhitzt  24 Stunden auf 110-120 0 C und treibt nach  beendigter Kondensation das Chlorbenzol mit  Wasserdampf ab.

   Der     Destillationsrückstand       wird in verdünnter Lauge neutral gelöst, die  Lösung erkalten gelassen, das     Natriumsalz          der        gebildeten        Carbonsäure        mit        15%        Koch-          salz    ausgefällt,     abfiltriert    und getrocknet. Das  Enderzeugnis ist ein in Wasser klar lösliches,  bräunliches Pulver.



  Process for the preparation of a condensation product. The present patent relates to a process for the preparation of a condensation product, characterized in that 3,5-di (chloromethyl) -2-oxy-benzoic acid is reacted with 2 moles of 2-octadecylaminobenzoic acid. As sodium salt, the new compound forms a brownish powder that is clearly soluble in water and has strong subatantive properties. It is suitable as a softening agent for all types of rayon and can be used at the same time as direct dyes in the dye bath.



  <I> Example: </I> 76 parts of 2-octadecylaminobenzoic acid are dissolved in 350 parts of chlorobenzene and 41.3 parts of 71.5% strength 3,5-di (chloromethyl) -2-oxy-benzoic acid are added. The mixture is heated to 110-120 ° C. for 24 hours and, after the condensation has ended, the chlorobenzene is driven off with steam.

   The distillation residue is dissolved neutrally in dilute lye, the solution is allowed to cool, the sodium salt of the carboxylic acid formed is precipitated with 15% sodium chloride, filtered off and dried. The end product is a brownish powder that is clearly soluble in water.
