Description

  

  Verfahren zur Herstellung eines neuen     Zwischenproduktes    der Teerfarbenindustrie.    Es     wurde    gefunden, dass man ein neues  Zwischenprodukt, das tertiäre Kondensations  produkt von einem     Mol.        Cya,nurchlarid    mit  einem Mal.

       1,8-Aminonaphtol-3,6-disulfosäure     und zwei     Mol.        Methylialkahol,    erhält, wenn  man auf ein     Mol.        Cya.nurchlorid    in beliebiger  Reihenfolge ein     Mol.        1,8-Aminon.aphtol-3,6-          clisulfosäure    und zwei     Mol.    Methylalkohol  einwirken lässt.  



  Diese Kondensation wird durch     Zusam-          menrühren,der    Komponenten in einem     geeig-          n,        ten    Verdünnungsmittel     durchgeführt.    Das  tertiäre     Kondensationsprodukt    aus einem     Mol.          Cyanurchlorid    mit einem     Mol.        :

  ,8-Amino-          naphtol-3,6-disulfosäure    und zwei     Mol.        Me-          thylalkoho,1    bildet als     Alkalisalz    ein in Was  ser lösliches, fast farbloses Pulver. Es ent  hält kein reaktionsfähiges Chloratom mehr  und stellt ein wertvolles Ausgangsmaterial  zur     Herstellung    von Farbstoffen dar.  



       Beispiel:     <B>18,5</B> Teile     Cyanurchlorid    werden in 100  Teilen Benzol gelöst, und unter Kühlen trop  fenweise mit     einerNatriummethylatlösung    aus  4,6 Teilen. Natrium und 100 Teilen Methyl-         alkohol    versetzt. Das     Reaktionsgemisch        wird     hierauf mit einer wässerigen Lösung von  33,1 Teilen des     Dinatriumsalzes    der     1,8-Ami-          nonaphtol-3,6-sulfosäure    versetzt.

   Die ganze  Masse wird dann auf ca. 95<B>'</B>erhitzt und unter  gleichzeitigem     Abdestillieren    des Benzols so  lange bei dieser Temperatur ,gerührt bis die       Aminonaphtolsulfosäure    beinahe verschwun  den ist. Das tertiäre     Kondensationsprüdukt     aus einem     Mol.        Cyanurchlorid    mit zwei     Mol.          .Methyl.alko-hol    und einem     Mol.        1,8-Amino-          naphtol-3,6-,disulfosäure        wind    hierauf durch       Aussalzen    und     Aussäuern    abgeschieden,

   fil  triert und ,getrocknet.



  Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate, the tertiary condensation product of one mole. Cya, can be nurchlarid all at once.

       1,8-aminonaphthol-3,6-disulfonic acid and two moles of methyl alcohol, if one mole of 1,8-aminonaphthol-3,6-clisulfonic acid and two moles of cyanogen chloride are obtained in any order Allow methyl alcohol to take effect.



  This condensation is carried out by stirring the components together in a suitable diluent. The tertiary condensation product of one mole of cyanuric chloride with one mole:

  , 8-Amino-naphthol-3,6-disulphonic acid and two moles of methyl alcohol, 1, as the alkali metal salt, forms an almost colorless powder that is soluble in water. It no longer contains a reactive chlorine atom and is a valuable starting material for the production of dyes.



       Example: 18.5 parts of cyanuric chloride are dissolved in 100 parts of benzene, and with cooling, dropwise with a sodium methylate solution of 4.6 parts. Sodium and 100 parts of methyl alcohol are added. The reaction mixture is then treated with an aqueous solution of 33.1 parts of the disodium salt of 1,8-aminonaphthol-3,6-sulfonic acid.

   The whole mass is then heated to approx. 95 <B> '</B> and, while simultaneously distilling off the benzene, stirred at this temperature until the aminonaphthol sulfonic acid has almost disappeared. The tertiary condensation product of one mole of cyanuric chloride with two moles of methyl alcohol and one mole of 1,8-amino-naphthol-3,6-, disulfonic acid is then deposited by salting out and acidifying,

   fil trated and, dried.
