Description
Verfahren zur Herstellung eines Diazopräparates aus einem festen Aryldiazoniumboi-fluorid. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines Diazoprä- parates aus einem festen Aryldiazoniumbor- fluorid, dadurch gekennzeichnet,, dass man Diazoniumborfluorid des tetrazotierten Di- anisidins mit Kaliumnitrat und entwässertem Natriumsulfat vermischt.
Das so erhaltene Präparat zeigt gegen über einem ohne Zusatz von Kaliumsalz her gestellten eine erhöhte Löslichkeit. Es kann zur Herstellung von Farbstoffen Verwen dung finden.
<I>Beispiel:</I> 39 Teile Diazoniumborfluorid des tetra- zotierten Dianisidins, dessen Löslichkeit 7,5 gr Dianisidinbase Mol. Gew. 244 im Liter bei 20' C entspricht, werden mit 45 Teilen entwässertem Natriumsulfat und 9 Teilen Kaliumnitrat vermischt. Die Löslichkeit die ses Präparates in Wasser entspricht bei 20 C 45 gr Dianisidinbase lol. Gew. 244.
Process for the production of a diazo preparation from a solid aryldiazonium fluoride. The present patent relates to a process for the production of a diazo preparation from a solid aryldiazonium borofluoride, characterized in that the diazonium borofluoride of the tetrazotized dianisidine is mixed with potassium nitrate and dehydrated sodium sulfate.
The preparation obtained in this way shows an increased solubility compared to one made without the addition of potassium salt. It can be used to make dyes.
<I> Example: </I> 39 parts of diazonium borofluoride of tetrazotized dianisidine, the solubility of which corresponds to 7.5 g dianisidine base mol. Wt. 244 per liter at 20 ° C., are mixed with 45 parts of dehydrated sodium sulfate and 9 parts of potassium nitrate. The solubility of this preparation in water corresponds to 45 grams of dianisidine base lol at 20 C. Weight 244.
