Description

  

  Verfahren zur Herstellung einer in     hydroaylgruppenhaltigen    organischen  Lösungsmitteln löslichen Chromverbindung des     TriphenylmethanfarbstofFes    aus       p-Dimethylaminobenzaldehyd    und     o-gresotinsäure.       Gegenstand dieses Patentes ist ein Ver  fahren zur Darstellung einer in     hydrogyl-          gruppenhaltigen,    organischen     Lösungsmitteln     löslichen Chromverbindung des     Triphenyl-          methanfarbstoffes    aus     p-Dimethylaminobenz-          aldehyd    und     o-Kresotinsäure.    Behandelt man,

    zweckmässig unter Erhitzen, die zum Bei  spiel nach üblichem Verfahren dargestellte,  in Wasser und organischen     Lösungsmitteln     unlösliche     Chromverbindung    des     Triphenyl-          methanfarbstoffes    aus     p-Dimethylaminobenz-          aldehyd    und     o-Kresotinsäure    mit Salzsäure  oder Verbindungen, die Salzsäure abspalten,  in Gegenwart von organischen Verdünnungs  mitteln, so erhält man nach dem Verjagen  des Verdünnungsmittels     ein        violettes,    gelb  glänzendes     Pulver,

      das in     niederen    Alkoholen  sehr gut löslich ist und dessen Lackfärbun  gen sich durch sehr gute Lichtechtheit aus  zeichnen.     Beispiel:     106 Teile der unlöslichen Chromverbin  dung des     Triphenylmethanfarbstoffes    aus  1     Mol.        p-Dimethylaminobenzaldehyd    konden  siert mit 2     Mol.        o-Kresotinsäure,    geben b<U>eim</U>  Rühren in 500 Teilen Alkohol bei 60 bis  <B>78'</B> C, mit 50 Teilen 31%iger Salzsäure    tropfenweise     in    60     Minuten    versetzt, eine  klare violette Lösung.

   Durch     Abdestillieren     des Alkohols     und    Trocknen des Rückstandes  im Vakuum erhält man die in niederen Al  koholen zu 10 oder mehr Prozent lösliche neue  Verbindung als     violettes,    gelbglänzendes  Pulver.



  Process for the preparation of a chromium compound of the triphenylmethane dye from p-dimethylaminobenzaldehyde and o-gresotinic acid which is soluble in organic solvents containing hydroal groups. The subject of this patent is a process for the preparation of a chromium compound of triphenyl methane dye made from p-dimethylaminobenzaldehyde and o-cresotinic acid which is soluble in organic solvents containing hydrogyl groups. Are you treating

    expediently with heating, the chromium compound of the triphenyl methane dye made from p-dimethylaminobenzaldehyde and o-cresotinic acid with hydrochloric acid or compounds that split off hydrochloric acid, which is insoluble in water and organic solvents, in the presence of organic diluents, after chasing away the diluent, a violet, yellow shiny powder is obtained,

      which is very soluble in lower alcohols and whose lacquer colors are characterized by very good lightfastness. Example: 106 parts of the insoluble chromium compound of the triphenylmethane dye from 1 mole of p-dimethylaminobenzaldehyde condenses with 2 moles of o-cresotinic acid, give it with stirring in 500 parts of alcohol at 60 to 78 ' </B> C, with 50 parts of 31% hydrochloric acid added dropwise over 60 minutes, a clear purple solution.

   By distilling off the alcohol and drying the residue in vacuo, the new compound, which is 10 percent or more soluble in lower alcohols, is obtained as a violet, shiny yellow powder.
