Verfahren zur Darstellung von Chlorderivaten des Indigos sowie seiner Homologen.Process for the preparation of chlorine derivatives of indigo as well as its homologues.
Zusatz zum Patente 160817 vom 24. Februar 1904.Addendum to patent 160817 of February 24, 1904.
Patentiert im Deutschen Reiche vom 3. Mai 1904 ab. Längste Dauer: 23. Februar 1919.Patented in the German Empire on May 3, 1904. Longest duration: February 23, 1919.
In der Patentschrift 160817 ist ein Verfahren zur Darstellung· von beständigen Chlorderivaten des Indigos und seiner Homologen beschrieben, welches dadurch gekennzeichnet ist, daß man Chlor oder chlorentwickelnde Substanzen auf Indigo oder seine Homologen bei Abwesenheit von Wasser in Gegenwart von Halogenverbindungen des Phosphors und Schwefels, event.In patent specification 160817 is a method for the representation of permanent chlorine derivatives of indigo and its homologues described, which is characterized in that one chlorine or chlorine-evolving Substances on indigo or its homologues in the absence of water in the presence of halogen compounds of phosphorus and sulfur, event.
auch bei Gegenwart von Chlorüberträgern behandelt.treated even in the presence of chlorine carriers.
Es wurde nun gefunden, daß in diesem Verfahren an Stelle der genannten Halogenverbindungen organische Säurechloride, z. B.It has now been found that in this process, instead of the halogen compounds mentioned organic acid chlorides, e.g. B.
Acetylchlorid oder Benzoylchlorid, mit Erfolg verwendet werden können.Acetyl chloride or benzoyl chloride, with success can be used.
Das Verfahren wird durch folgendes Beispiel erläutert:The procedure is illustrated by the following example:
20 Teile Indigo werden in 100 Teilen Acetylchlorid suspendiert, worauf man unter ao guter Kühlung Chlor im Überschuß einleitet. Das Reaktionsprodukt wird direkt abgesaugt und mit heißer verdünnter Natronlauge behandelt. 20 parts of indigo are suspended in 100 parts of acetyl chloride, whereupon under ao good cooling introduces excess chlorine. The reaction product is filtered off directly and treated with hot dilute caustic soda.
