Description
Es ist ein Verfahren bekannt, nach welchem durch Einwirkung von naszierendem Chlor oder Brom auf Perylen in Suspension, z. B. in Eisessig, Halogenperylene dargestellt werden können. Es wurde nun gefunden, daß die Halogenisierung im allgemeinen bedeutend besser durchführbar ist, ja in manchen Fällen erst dann möglich ist, wenn man die Einwirkung in Lösung vornimmt. Als Lö-A method is known, according to which by the action of nascent Chlorine or bromine on perylene in suspension, e.g. B. represented in glacial acetic acid, haloperylenes can be. It has now been found that halogenation is generally significant is more feasible, and in some cases is only possible if you have the Acts in solution. As a lo-
xo suiigsmittel kommen Verbindungen, wie Nitrobenzol, in Betracht. Nach dem neuen Verfahren gelingt es sehr leicht, Di-, Tetra-, Penta- und Hexachlorperylen sowie Dichlorperylenchinon in sehr reinem Zustande in guter Ausbeute zu gewinnen.xo suiigsmittel come compounds such as nitrobenzene, into consideration. The new process makes it very easy to produce di-, tetra-, Penta- and hexachloroperylene and dichloroperylenequinone in a very pure state in good yield to gain.

When the reaction has ended, the reaction mixture is left to crystallize in the cold for 24 hours. The Däohlorperylen thus obtained is already well crystallized in the raw state. The product dissolves in the lower-boiling solvents, such as alcohol, ether and glacial acetic acid, little, better in benzene and xylene, easily in aniline and nitrobenzene in the warmth, from which it crystallizes in brown-yellow needles. In cold conc. Sulfuric acid is difficult to dissolve, in warm easily with ultramarine blue color. The solutions in benzene, xylene and similar other solvents are yellow in color and green in fluorescence. The melting point of the pure product is 280 ° (unk.)
