Description

Verfahren zur Darstellung von Dioxyperylen. Vorliegende Erfindung hat ein Verfahren zur Darstellung eines Dioxyperylen genannten Abkömmlings des Perylens (C20, H1_) zum Gegenstand und besteht im wesentlichen darin, (laß Diall:3rläther der Dio\yStlbstitütionspro- dukte des i,i'-Dinaplitli3#ls, mit Konden- sationsinitteln vermischt, auf eine unter der Schnmlztempcratur des betreffenden Dioxy- pcrvlens liegende Temperatur erhitzt «-erden, worauf (las Dioxyperylen durch Auslaugen von (her Masse getrennt und gereinigt «-erden kann.

The present invention has a method for the preparation of a dioxyperylene mentioned Descendant of perylene (C20, H1_) to the Object and consists essentially in (let Diall: 3rlether of the Dio \ yStlbstitütionspro- ducts of the i, i'-Dinaplitli3 # ls, with condensate sationinmittel mixed, on one under the Melting temperature of the dioxy- pcrvlens lying temperature heated «-erden, whereupon (read dioxyperylene by leaching from (earth separated and purified "earth can.

The measure is used for the purpose of expiry of the laondcnsationsinittcls or its decomposition zunngsprodtlkle 1171t a suitable maintenance in medium, i111 assumed execution game with dilute hydrochloric acid, reached and the solid residue, which is the main thing Dioxyperylene consists, cleaned from the adhering liquid by filtration, best with the aid of negative pressure.
