naphtol - a2 - sulfosäure.naphtol - a 2 - sulfonic acid.
In der Patentschrift Nr. 63074 werden blaue Substantive Farbstoffe beschrieben, welche aus gewissen Tetrazokörpern durch Combination mit der Benzoylverbindung derjenigen Ct1 c^-Amidonaphtolmonosulfosä'ure entstehen, die durch Verschmelzen der ci^-Naphtylamindisulfosäure S dargestellt wird. Es wird in der Patentschrift angegeben, dafs diese Ct1 c^-Amidonaphtolmonosulfosäure selbst sich zur Darstellung blauer substantiver Farbstoffe nicht eigne, da sie mit den Tetrazoverbindungen des Benzidins und ähnlicher Basen — ebenso wie die durch Sulfuriren von Ct1 ci4-Amidonaphtol entstehende Sulfosäure — nur Farbstoffe von stumpfem Ton und geringem Werth liefern soll.In the patent specification No. 63074 blue nouns dyes are described, which are formed from certain tetrazo bodies by combining with the benzoyl compound of that Ct 1 c ^ -amidonaphthol monosulphonic acid, which is produced by fusing the ci ^ -naphtylamine disulphonic acid. It is stated in the patent that this Ct 1 c ^ amidonaphthol monosulphonic acid itself is unsuitable for the preparation of blue substantive dyes, since it reacts with the tetrazo compounds of benzidine and similar bases - just like the sulphonic acid formed by sulphurizing Ct 1 ci 4 amidonaphthol - should only provide dyes of dull tone and of little value.
Im Gegensatz hierzu hat sich nun ergeben, dafs gerade die durch Verschmelzen der a - Naphtylamindisulfosäure S erhaltene Ct1 c^-Amidonaphtolmonosulfosäure mit gewissen Tetrazoverbindungen, wie Tetrazoditolyl und Tetrazodianisol brauchbare Farbstoffe liefert; ferner hat sich gezeigt, dafs die genannte' Ci1 Ci4 - Amidonaphtolmonosulfosäure mit den erwähnten Tetrazokörpern ein Zwischenproduct zu liefern im Stande ist, welches noch eine freie Diazogruppe enthält und daher noch mit ι Mol. eines Amins, Phenols bezw. deren Sulfosäuren combinirt werden kann.In contrast, now has arisen, that just by fusion of a - provides Naphtylamindisulfosäure S obtained Ct 1 c ^ -Amidonaphtolmonosulfosäure with certain Tetrazoverbindungen as Tetrazoditolyl and Tetrazodianisol useful dyes; It has also been shown that the said 'Ci 1 Ci 4 - amidonaphtolmonosulfonic acid is able to deliver an intermediate product with the tetrazo bodies mentioned, which still contains a free diazo group and therefore still contains ι mol. of an amine, phenol or. the sulfonic acids of which can be combined.
Von besonderem technischen Werth erwies sich derjenige gemischte Farbstoff, welcher aus ι Mol. Tetrazodianisol, 1 Mol. Ct1 ai - Amidonaphtolmonosulfosäure und ι Mol. ß-napbtoldisulfosaurem Natron R entsteht.. Of particular industrial value is the one mixed dye, which from ι Tetrazodianisol mol, 1 mol proved Ct 1 a i -. Amidonaphtolmonosulfosäure and ι mole of ß-R napbtoldisulfosaurem soda is produced..
Bei der Darstellung des Farbstoffes verfährt man wie folgt:The procedure for displaying the dye is as follows:
24,4 kg Dianisidin werden in bekannter Weise in die Tetrazoverbindung übergeführt; die Lösung der letzteren giebt man zu einer durch ,Soda alkalisch gehaltenen Lösung von 23,9 kg Ct1 a4-Amidonaphtolmonosulfosäure; das Zwischenproduct scheidet sich in Form eines blauschwarzen Niederschlages ab. Sobald die Bildung desselben beendet ist, fügt man eine Lösung von 34,8 kg β - naphtoldisulfosaurem Natron R zu und läfst die Mischung längere Zeit rühren. Alsdann wird angewärmt, der Farbstoff mit Salzwasser ausgefällt und abfiltrirt, geprefst und getrocknet. Er färbt ungeheizte Baumwolle im Seifen- oder Salzbade prachtvoll grünstichig 'blau.24.4 kg of dianisidine are converted into the tetrazo compound in a known manner; the solution of the latter is added to a solution, kept alkaline by soda, of 23.9 kg of Ct 1 a 4 amidonaphthol monosulfonic acid; the intermediate product is deposited in the form of a blue-black precipitate. As soon as the formation of the same has ended, a solution of 34.8 kg of β-naphthol-disulfo-acid sodium R is added and the mixture is left to stir for a long time. Then it is warmed up, the dye is precipitated with salt water and filtered off, pressed and dried. It dyes unheated cotton in a soap or salt bath with a magnificent greenish tinge of blue.
