Description
Verfahren zur Darstellung von 11Zonobrom-Bz1, Bz1'-Benzantluonylsulfid. Es wurde gefunden, dass die Benzantliro- nylmeikaptane, -disulfide und -sulfide, sowie ihre Derivate beim Behandeln mit Halogen oder halogenabspaltenden Mitteln in Halogen substitutionsprodukte übergehen.
Gegenstand dieses Patentes ist ein Ver fahren zur Darstellung von Monobrom-Bzl, Bzl'-benzanthronylsulfid durch Umsetzung von Bz1, Bzl'-benza.nthronylsulfid mit einem Br omierungsmittel.
Das AIonobrom-Bzl, Bzl'-benzantlirony 1- sulfid ist ein wichtiges Zwischenprodukt zur Herstellung von Farbstoffen.
Beispiel 100 Gewichtsteile Bzl, Bzl'-benzanthro- nylsulfid werden in 1000 Gewichtsteile Chlorsulfonsäure bei minus 5 C eingerührt und allmählich 17 Gewichtsteile Brom zuge- geben. Nachdem alles Brom verbraucht ist, wird auf Eis gegossen und das Bromierungs- produkt wie üblich isoliert. Es stellt ein orangegelbes Pulver dar, das sich in konzen trierter Schwefelsäure mit blaugrüner Farbe löst.
Process for the preparation of 11zonobromo-Bz1, Bz1'-benzantluonyl sulfide. It has been found that the benzantliro- nylmeikaptans, -disulfides and -sulfides, as well as their derivatives, convert into halogen substitution products when treated with halogen or halogen-releasing agents.
The subject of this patent is a process for the preparation of monobromo-Bzl, Bzl'-benzanthronyl sulfide by reacting Bz1, Bzl'-benza.nthronyl sulfide with a bromination agent.
The Alonobrom-Bzl, Bzl'-benzantlirony 1- sulfide is an important intermediate for the production of dyes.
Example 100 parts by weight of Bzl, Bzl'-benzanthanyl sulfide are stirred into 1000 parts by weight of chlorosulfonic acid at minus 5 ° C., and 17 parts by weight of bromine are gradually added. After all the bromine has been consumed, it is poured onto ice and the bromination product is isolated as usual. It is an orange-yellow powder that dissolves in concentrated sulfuric acid with a blue-green color.
