Description

  

  Verfahren zur Herstellung eines Gemisches     kernalkylierter    aromatischer  Verbindungen.    Bei der katalytischen Reduktion des Koh  lenoxydes     bezw.        kohlenoxydhaltiger    Gase mit  Wasserstoff entstehen neben Methanol eine  Reihe höherer Alkohole mit verzweigter     Koh-          lenstoffkette    und einer Kettenlänge von etwa       C5-C12,    aus denen sich durch     Dehydrati-          sierung    und     Polymerisierung    ein Gemisch  höherer     Olefine    herstellen lässt.  



  Es wurde gefunden, dass man durch Ein  wirkung der von     180-2200    C siedenden  Fraktion eines solchen polymerisierten     Ole-          fingemisches    auf     Phenoxyessigsäure    in guter  Ausbeute ein Gemisch     kernalkylierter        Phen-          oxyessigsäuren    erhält.  



  Als Katalysatoren können die bekannten  Substanzen, wie     Borfluorid    und seine Mole  külverbindungen, Aluminiumchlorid, Schwe  felsäure u. a., dienen.  



  Das so erhaltene Säuregemisch kann als  Textilhilfsmittel oder als Ausgangsmaterial  hierfür verwendet werden.         Beispiel:     152 Gewichtsteile     Phenoxyessigsäure    wer  den bei<B>700</B> C in 800 Gewichtsteilen Tetra  chlorkohlenstoff gelöst und 30 Gewichtsteile       Borfiuorid    eingeleitet.

   Dann werden bei 60   C  185 Gewichtsteile     Olefin    von den Siedegren  zen     180--2200,    das durch     Dehydratisierung     und     Polymerisierung    der bei der katalytischen  Reduktion von Kohlenoxyd oder     kohlenoxyd-          haltiger    Gase entstehenden Alkohole mit etwa  5-12     C-Atomen    gewonnen wird, eingetragen.       Man    rührt zwei Stunden lang bei 60   C und  15 Stunden lang bei Zimmertemperatur. Nach  dem Waschen des Reaktionsproduktes mit  Wasser und dem Trocknen geht das Gemisch  der     Alkylplsenoxyessigsäureri    im Vakuum von  2 mm bei 170-225   C über.

   Ausbeute     87'/0     der Theorie.  



  Das so gebildete     Alkylphenoxyessigsäure-          gemisch    bildet ein hellgelbes, viskoses<B>01,</B>  das in     Sodalösung    löslich ist.



  Process for the preparation of a mixture of ring-alkylated aromatic compounds. In the catalytic reduction of the Koh lenoxydes respectively. Carbon-oxide-containing gases with hydrogen, in addition to methanol, produce a number of higher alcohols with a branched carbon chain and a chain length of around C5-C12, from which a mixture of higher olefins can be produced by dehydration and polymerisation.



  It has been found that the action of the fraction boiling from 180-2200 C of such a polymerized olefin mixture on phenoxyacetic acid gives a mixture of ring-alkylated phenoxyacetic acids in good yield.



  As catalysts, the known substances such as boron fluoride and its Mole külverbindungen, aluminum chloride, sulfuric acid and. a., serve.



  The acid mixture thus obtained can be used as a textile auxiliary or as a starting material for this. Example: 152 parts by weight of phenoxyacetic acid are dissolved in 800 parts by weight of carbon tetrachloride at 700 C and 30 parts by weight of boron fluoride are introduced.

   Then 185 parts by weight of olefins with a boiling point of 180--2200, which is obtained by dehydrating and polymerizing the alcohols with about 5-12 carbon atoms formed during the catalytic reduction of carbon oxides or gases containing carbon oxides, are introduced at 60 C. The mixture is stirred for two hours at 60 ° C. and for 15 hours at room temperature. After the reaction product has been washed with water and dried, the mixture of alkylplsenoxyacetic acids passes over in a vacuum of 2 mm at 170-225 ° C.

   Yield 87% of theory.



  The resulting alkylphenoxyacetic acid mixture forms a pale yellow, viscous 01, which is soluble in soda solution.
