PATENTAMT.PATENT OFFICE.

In der Patentschrift Nr. 66361 sind Verfahren zur Darstellung eines bei 2100 C. schmelzenden neuen Indulins von der Zusammensetzung C24 H19 Ns beschrieben.In the patent specification no. 66361 process for the preparation of a melt at 210 0 C. new Indulins of the composition C 24 H 19 N s are described.

Es hat sich nun gezeigt, dafs das niedere Homologe des genannten Indulins, nämlich das Indulin von der Zusammensetzung C23 Η N3. sich in ganz analoger Weise, wie dies in der obigen Patentschrift beschrieben ist, darstellen läfst.It has now been shown that the lower homologue of the indulin mentioned, namely indulin, has the composition C 23 Η N 3 . can be represented in a completely analogous manner to that described in the above patent specification.

So bildet sich das Indulin C23H11N3 This is how the indulin C 23 H 11 N 3 is formed

Mit Salzsäure liefert dasselbe ein in Wasser leicht lösliches Chlorhydrat. Dasselbe ist ebenso wie dasjenige des Indulins C24 Hi9 N3 zum Färben von Baumwolle und Seide geeignet, die Nuance ist etwas blauer als die des höheren Homologen.C 16 H n N 3 or of eurhodol C 16 H 10 N 2 O with aniline and aniline salt formed phenyleurhodine when treating the same with iodomethyl according to the methods given in patent specification No. 66361, claim 1 and examples 1 and 2. With hydrochloric acid it gives a hydrochloride which is easily soluble in water. Like that of indulin C 24 H 19 N 3, it is suitable for dyeing cotton and silk; the shade is somewhat bluer than that of the higher homologue.
