Zusatz zum Patent 285572 *).Addition to patent 285572 *).
Patentiert im Deutschen Reiche vom 15. Oktober 1912 ab. Längste Dauer: 13. Mai 1927.Patented in the German Empire on October 15, 1912. Longest duration: May 13, 1927.
Durch Patent 285572 und dessen Zusatzpatent 286667 ist ein Verfahren zur Darstellung eines Bismethylaminotetraminoarsenobenzols geschützt, welches darin besteht, daß man auf p-Dimethylanilinarsenoxyd Nitriersäure zur Einwirkung bringt und die so erhaltene Dinitromethylnitraminophenyl - ρ - arsinsäure mit Schwermetallen bzw. mit Schwermetallsalzen in saurer Lösung reduziert.A method of representation is provided by patent 285572 and its additional patent 286667 a bismethylaminotetraminoarsenobenzene protected, which consists in that one brings nitrating acid to action on p-dimethylanilinarene oxide and the resulting dinitromethylnitraminophenyl - ρ - arsic acid reduced with heavy metals or with heavy metal salts in acidic solution.
In der ersten Phase dieses Verfahrens wird die ajs Ausgangsstoff dienende aromatische Arsenverbindung mit dreiwertigem Arsen zur Arsinsäure oxydiert. Es ist nun, wie gefunden wurde, auch möglich, von jeder anderen Arsenverbindung des Dimethylanilins auszugehen, die der gleichen Oxydationsstufe angehört und bei der Einwirkung von Nitriersäure p-Dimethylanilinarsinsäure liefert, oder von der fertiggebildeten Arsinsäure selbst.In the first phase of this process, the ajs starting material is used aromatic Arsenic compound oxidized with trivalent arsenic to arsinic acid. It is now as found became possible to start from any other arsenic compound of dimethylaniline, which belongs to the same stage of oxidation and, when exposed to nitrating acid, p-dimethylanilinarsinic acid supplies, or from the finished arsic acid itself.
i. Nitrierung von p-Dimethylanilinarsenchlorür. i. Nitration of p-dimethylanilinarium chloride.
4 Teile p-Dimethylanilinarsenchlorür (Ann; d. Chem. 270 [1892], S. 141) werden in 40 Teilen konzentrierter Schwefelsäure gelöst, bei 0 bis io° mit einem Gemisch von je 6 Teilen kon-4 parts of p-dimethylanilinarium chloride (Ann; d. Chem. 270 [1892], p. 141) are in 40 parts concentrated sulfuric acid, at 0 to 10 ° with a mixture of 6 parts each
zentrierter Schwefelsäure und rauchender Salpetersäure versetzt und unter Rühren 5 Stunden auf 40 bis 50 ° erwärmt. Nach dem Erkalten gießt man auf etwa 100 Teile Eis und saugt die abgeschiedene Dinitromethylnitraminophenyl-p-arsinsäure ab. Sie wird mit Wasser gut abgewaschen, getrocknet und nach den im Hauptpatent bzw. dessen Zusatzpatent 286667 beschriebenen Verfahren weiterbehandelt.centered sulfuric acid and fuming nitric acid added and heated to 40 to 50 ° with stirring for 5 hours. After cooling down it is poured onto about 100 parts of ice and the separated dinitromethylnitraminophenyl-p-arsic acid is sucked away. It is washed off well with water, dried and according to the main patent or its additional patent 286667 described method further treated.
2. Nitrierung von p-Dimethylanilinarsinsäure.2. Nitration of p-dimethylanilinarsinic acid.
4 Teile p-Dimethylanilinarsinsäure (vgl. Patentschrift 200065, Kl.i2q) werden in 40 Teilen konzentrierter Schwefelsäure gelöst und wie im Beispiel 1 mit 12 Teilen Nitriersäure nitriert.4 parts of p-dimethylanilinarsinic acid (see patent specification 200065, class i2q) are in 40 parts Dissolved concentrated sulfuric acid and nitrated as in Example 1 with 12 parts of nitrating acid.
