KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In dem Patent 281422 wurde gezeigt, daß die aus Purpurin durch Sulfieren erhältliche Purpurinsulf osäure (1 · 2 · 4-Trioxyanthrachinon-3-sulfosäure) wertvolle Tonerdelacke liefert.In the 281422 patent it was shown that that obtainable from purpurin by sulphonation Purpurinsulfonic acid (1 x 2 x 4-trioxyanthraquinone-3-sulfonic acid) supplies valuable alumina lacquers.
Es wurde nun gefunden, daß auch die heteronuklearen Purpurinsulfosäuren, z. B. die Purpurin-a-sulfosäure (Patent 155045, Kl. 22b) sowie die aus Purpurin durch starkes Sulfieren und nachheriges Abspalten der in 3-Stellung befindlichen Sulfogruppe (analog dem Verfahren der Patente 56951, Kl. 22, und 56952, Kl. 22) erhältlichen heteronuklearen Purpurin-ß-sulfosäuren (s. auch Patent 154337, Kl..22b) ebenfalls wertvolle Tonerdelacke liefern, die wesentlich blaustichiger sind als die mit Purpurin-3-sulfosäure hergestellten.It has now been found that the heteronuclear purpurinsulfonic acids, e.g. B. the Purpurin-a-sulfonic acid (patent 155045, class 22b) as well as that from purpurin by strong sulfonation and subsequent cleavage of the sulfo group located in the 3-position (analogous to the process of patents 56951, class 22, and 56952, class 22) obtainable heteronuclear purpurin-ß-sulfonic acids (See also Patent 154337, Cl..22b) as well provide valuable alumina lacquers that are much more bluish than those with purpurine-3-sulfonic acid manufactured.
100 kg schwefelsaure Tonerde (18 Prozent Al2O3),100 kg sulfuric alumina (18 percent Al 2 O 3 ),
1,25 - Purpurin-6- bzw. 7-sulfosäure, Kali oder Natronsalz, werden unter Erwärmen in1.25 - Purpurin-6- or 7-sulfonic acid, potash or sodium salt, are heated in
iooo 1 Wasser gelöst und mit einer Lösung von 40 kg kalzinierter Soda in 400 - Wasser gefällt.iooo 1 water and with a solution of 40 kg calcined soda in 400 - water like.
1,25 kg Purpurin-a-sulfosäure (s. Patent 155045) werden in Wasser gelöst und mit1.25 kg of purpurin-a-sulfonic acid (see patent 155045) are dissolved in water and with
60,0 - Tonerdehydrat i. Tg. (10 Prozent Al2[OH]6) aufgekocht.60.0 - alumina hydrate i. Tg. (10 percent Al 2 [OH] 6 ) boiled up.
