Description
Verfahren zur Herstellung von Eisenoxyd. Die Erfindung betrifft ein Verfahren zur Herstellung von Eisenoxyden in feinst verteilter Form unter Zuhilfenahme von zur feinsten Zerteilung gebrachten höheren und niederen Pilzen.Process for the production of iron oxide. The invention relates to a Process for the production of iron oxides in finely divided form with the aid of higher and lower mushrooms brought to the finest division.
Gemäß der Erfindung werden Pilze unter Druck oder durch Fermentation mittels Wasser zu einer schleimigen Masse abgebaut und zusammen mit Eisensulfat oder Eisenhydroxyd sofort oder nach vorhergehendem Trocknen geglüht.According to the invention, mushrooms are produced under pressure or by fermentation broken down into a slimy mass by means of water and combined with iron sulfate or iron hydroxide calcined immediately or after previous drying.
Abgesehen von ihrer Billigkeit enthalten die zur Herstellung von Eisenoxyd benutzten Pilze Stickstoff in erheblichen Mengen, welcher beim Glühen Verbindungen eingeht, die dem Polierrot eine Härte geben, welche für seinen technischen Verwendungszweck (z. B. als Schleifmittel für optische Gläser) notw endig ist. Das nach dem Verfahren gemäß der Erfindung hergestellte Oxyd besitzt eine Feinheit, welche dem aus Oxalsäure hergestellten Oxyd gleichwertig ist.Apart from their cheapness, those used to manufacture contain iron oxide Mushrooms used nitrogen in significant amounts, which compounds when glowing enters that give the polishing red a hardness that is suitable for its technical purpose (e.g. as an abrasive for optical glasses) is necessary. That after the procedure Oxide produced according to the invention has a fineness similar to that of oxalic acid produced oxide is equivalent.
In der Literatur wird hervorgehoben, daß das aus Oxalsäure hergestellte Polierrot hinsichtlich seiner Feinheit und seines Härtegrades den nach anderen Verfahren hergestellten Oxyden überlegen ist. Das gleiche ist der Fall bei dem nach vorliegender Erfindung hergestellten Polierrot.In the literature it is emphasized that the one made from oxalic acid Polished red in terms of its fineness and degree of hardness compared to other processes produced oxides is superior. The same is the case with that of the present Invention made polished red.
Versuche mit den mit den bekannten Ausgangsstoffen, wie Kohle, Kohlenruß o. dgl., hergestellten Oxyden haben ergeben, daß diese Erzeugnisse bei weitem nicht das günstige Ergebnis liefern, ganz abgesehen davon, daß bei ihrer Herstellung viel höhere Glühtemperaturen erforderlich sind als bei Verfahren gemäß der Erfindung.Experiments with the known starting materials, such as coal, carbon black o. The like., Oxides produced have shown that these products are far from give the favorable result, quite apart from the fact that much in their manufacture higher annealing temperatures are required than in processes according to the invention.
Es werden z. B. i ooo g Eisenvitriol in i 1 Wasser heiß gelöst und mit 6oo ccin aoprozentigem Amoniak gefällt und gleichzeitig 150 ccm Pilzschleim zugesetzt. Das Fällungsprodukt wird abgepreßt, gewaschen, getrocknet, gemahlen und geglüht.There are z. B. i ooo g iron vitriol dissolved in i 1 hot water and precipitated with 600 cc of ao-percent ammonia and at the same time 150 cc of mushroom slime added. The precipitate is pressed off, washed, dried, ground and annealed.
Oder es werden i ioo g wasserfreie Soda, welche in z 1 warmem Wasser gelöst sind, zu einer Lösung von 3 kg Eisenvitriol in vier Teilen warmem Wasser nebst 5oo ccni Pilzschleim unter langsamem Umrühren zugefügt. Das erhaltene Fällungsprodukt wird abgenutscht, ausgewaschen, getrocknet, gemahlen und geglüht.Or ioo g of anhydrous soda, which in z 1 warm water are dissolved, to a solution of 3 kg of iron vitriol in four parts of warm water together with 5oo ccni mushroom slime added while stirring slowly. The precipitate obtained is sucked off, washed out, dried, ground and annealed.
Bei der Herstellung der Pilzmasse kann man wie folgt verfahren: a. Druckverfahren: ioo g getrocknete Pilze werden mit goo g Wasser i bis aETage aufgequollen,dannineinem Autoklaven mit Rührwerk 1/_, bis i Stunde bei einem Druck von 3 bis 5 Atmosphären erhitzt. Es bildet sich ein zäher .Schleim, der durch Abseihen von etwa noch unzersetzt gebliebenen Pilzresten getrennt werden kann. b. Gärungsverfahren: Man läßt ioo g getrocknete Pilze, zu welchen goo g Wasser, eine Spur Essigsäure und Schimmelpilzsporen bei etwa 2o° zugesetzt sind, 2 bis 3 Wochen in einem bedeckten Ge-fäß stehen. Die Masse wird zeitweilig etwas umgerührt. Der erhaltene zähe Schleim wird durch Abpressen bzw. Abseihen von noch unfermentierten Zelluloserückständen getrennt.In the production of the mushroom mass one can proceed as follows: a. Printing process: 100 g of dried mushrooms are swollen with goo g of water for 1 to 3 days, then heated in an autoclave with a stirrer 1 / _ for 1 hour at a pressure of 3 to 5 atmospheres. A tough slime forms, which can be separated by straining any remaining undecomposed mushroom residues. b. Fermentation process: 100 g of dried mushrooms, to which 100 g of water, a trace of acetic acid and mold spores have been added at about 20 °, are allowed to stand for 2 to 3 weeks in a covered vessel. The mass is temporarily stirred a little. The viscous slime obtained is separated from cellulose residues that have not yet been fermented by pressing or straining.
