Description

  

  Verfahren zur Herstellung     eines        ehromierbaren        Farbstoffes.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines     chromier-          baren        Farbstoffes.    Das Verfahren ist dadurch  gekennzeichnet, dass man     diazotiertes        2-Amino-          1-oxy-benzol-4-methy        lsulfon    mit     1-Phenyl-3-          methyl-5-pyrazolon    vereinigt.  



  Der Chromkomplex des erhaltenen neuen  Farbstoffes stellt ein oranges Pulver dar, das  Wolle aus essigsaurem Bade in klaren orangen  Tönen von sehr guter     Lichteehtheit    sehr ein  heitlich färbt.  



  <I>Beispiel:</I>  18,7 Teile     2-Amino-l-oxy-benzol-4-methyl-          sulfon    werden in 150 Teilen heissem Wasser  mit 17 Teilen konzentrierter Salzsäure gelöst,  auf 50 abgekühlt und mit einer Lösung von  6,9 Teilen     Natriumnitrit        diazotiert.    Die     Diazo-          niumverbindung    fällt dabei teilweise in Form  lehmgelber Kristalle aus.

   Durch Zugabe von       Natriümbicarbonat    neutralisiert man die     über-          schüssige    Salzsäure und giesst. bei 50 auf eine  Lösung von 18,3 Teilen     1-Phenyl-3-methyl-5-          pyrazolon    und 20 Teilen wasserfreier Soda in  200 Teilen Wasser. Nach Beendigung der       Farbstoffbildung    salzt. man aus und filtriert  den     ausgeschiedenen    Farbstoff ab.

      Der Chromkomplex des Farbstoffes kann  erhalten werden, indem man ihn in 500 Teilen  Wasser     anschlämmt,    200 Teile einer Lösung  von     chromsalicylsaurem    Ammonium (entspre  chend 7,6 Teilen Chromoxyd) dazu gibt und  während einiger Stunden     zum    Sieden erhitzt.  Der chromhaltige Farbstoff scheidet sich da  bei während der     Chromierung    in feinkristal  liner Form weitgehend aus.     llan    filtriert ihn  ab, trocknet und vermischt den Farbstoff mit       Trinatriumphosphat,    Soda oder mit     Tetra-          nat.riumpyrophosphat.  



  Process for the production of an honorable dye. The subject of the present patent is a process for the production of a chromable dye. The process is characterized in that diazotized 2-amino-1-oxy-benzene-4-methyl sulfone is combined with 1-phenyl-3-methyl-5-pyrazolone.



  The chromium complex of the new dye obtained is an orange powder which uniformly colors wool from an acetic acid bath in clear orange tones of very good lightness.



  <I> Example: </I> 18.7 parts of 2-amino-1-oxy-benzene-4-methylsulfone are dissolved in 150 parts of hot water with 17 parts of concentrated hydrochloric acid, cooled to 50 and with a solution of 6 , 9 parts of sodium nitrite diazotized. The diazonium compound partially precipitates in the form of clay-yellow crystals.

   The excess hydrochloric acid is neutralized by adding sodium bicarbonate and poured. at 50 to a solution of 18.3 parts of 1-phenyl-3-methyl-5-pyrazolone and 20 parts of anhydrous soda in 200 parts of water. Salts after the formation of the dye. one out and filtered off the precipitated dye.

      The chromium complex of the dye can be obtained by slurrying it in 500 parts of water, adding 200 parts of a solution of chromium salicylic acid ammonium (corresponding to 7.6 parts of chromium oxide) and heating it to the boil for a few hours. The chromium-containing dye is largely separated out in fine crystalline form during the chromating process. Ilan filters it off, dries it and mixes the dye with trisodium phosphate, soda or with tetrasodium pyrophosphate.
