  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 182961.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man ehren neuen       Azofarbstoff    erhält, wenn man dianotiertes  4     -(4'-Methyl-)        phenoxyacetylamirro    - 2 -     äthoxy-          5-R-methoxyäthyläther-1-aminobenzol    mit     2,3-          Oxynaplrthoesäure-1'-naphthylamid    .vereinigt.  Der neue     Farbstoff    bildet ein blaues, in  Wasser unlösliches Pulver. Auf geeigneten  Substraten, wie zum Beispiel Zellulose, her  gestellt, färbt es diese in wertvollen, blauen  Tönen.  



  <I>Beispiel:</I>  37,4 Teile     4-(4'-Methyl-)phenoxyacetyl-          ami        no    - 2 -     äthoxy    - 5 -     (3-        methoxyäthyl        äther        -1-          aminobenzol    werden wie üblich dianotiert und  in eine Lösung von 31,3 Teilen     2,3-Oxy-          naphthoesäure-1'-naphthylamid,    60 Teilen  30      /oiger    Natronlauge, 30 Teilen Soda und  2000 Teilen Wasser eingetragen. Der ge  bildete Farbstoff fällt sofort aus. Der blaue  Niederschlag wird filtriert und getrocknet.  



  Das     4-(4'-Methyl-)phenoxyacetylamino-2-          äthozy-5-p-rnethoxyäthyläther-1-anrirrobenzol       kann hergestellt werden durch Umsetzen von       2,5-Dichlor-o-nitrobenzol    mit     Glykolmono-          methyläther    zum     4-Chlor-2-nitrobenzol-l-ss-          methoxyäthyläther.    Dieses wird dann zum       4-Chlor-2-aminobenzol-l-p-meth        oxyätbyläther     reduziert, welcher     acetyliert,

      nitriert und  durch Abspalten der     Acetylgruppe    in den       5-Nitro-4-chlor#-2-aminobenzol-l-p-metboxy-          äthyläther    übergeführt wird. Dieses Produkt  wird nun mit     Äthylalkohol    umgesetzt, wo  bei das     4-ständige    Chloratom durch die  Gruppe     002H5    ersetzt wird und hierauf  durch Kondensation mit     4-(Methyl-)phenoxy-          essigsäure    und Reduzieren in das     4-(4'-Me-          thyl-)

          phenoxyacetylamin        o-2-äth        oxy-5-        ss-m        eth-          oxyäthyläther-l-aminobenzol    umgewandelt  wird.



  <B> Additional patent </B> to main patent No. 182961. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 4 - (4'-methyl-) phenoxyacetylamirro-2-ethoxy-5-R-methoxyethyl ether-1-aminobenzene is used with 2,3-oxynaplrthoic acid-1'-naphthylamide. united. The new dye forms a blue, water-insoluble powder. Produced on suitable substrates such as cellulose, it colors them in valuable blue tones.



  <I> Example: </I> 37.4 parts of 4- (4'-methyl-) phenoxyacetylamine - 2 - ethoxy - 5 - (3-methoxyethyl ether -1- aminobenzene are dianotized as usual and put into a solution of 31.3 parts of 2,3-oxynaphthoic acid-1'-naphthylamide, 60 parts of 30% sodium hydroxide solution, 30 parts of soda and 2000 parts of water are introduced, the dyestuff formed precipitates out immediately. The blue precipitate is filtered and dried.



  The 4- (4'-methyl-) phenoxyacetylamino-2-ethoxy-5-p-methoxyethyl ether-1-anirrobenzene can be prepared by reacting 2,5-dichloro-o-nitrobenzene with glycol monomethyl ether to give 4-chloro-2 -nitrobenzene-l-ss- methoxyethyl ether. This is then reduced to 4-chloro-2-aminobenzene-l-p-methoxyethyl ether, which acetylates

      nitrated and converted by splitting off the acetyl group in the 5-nitro-4-chloro # -2-aminobenzene-l-p-metboxy-ethyl ether. This product is then reacted with ethyl alcohol, where the 4-position chlorine atom is replaced by the group 002H5 and then by condensation with 4- (methyl-) phenoxyacetic acid and reduction to the 4- (4'-methyl)

          phenoxyacetylamine o-2-ethoxy-5- ss-m ethoxyethylether-l-aminobenzene is converted.
