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.
