Description

Patenτ-Anspruch:Patenτ claim:

Verfahren zur Gewinnung von hochprocentigem Anthracen und anthracenhaltigen Gemengen, darin bestehend, dafs man diese in feste oder flüssige Fette (OeIe) und die daraus zu gewinnenden Fett- und Oelsäuren einträgt, worauf die das Anthracen begleitenden Körper iri Lösung gehen und auf mechanischem Wege (durch Filtriren und Pressen oder durch Extraction mit Petroleum und anderen geeigneten Flüssigkeiten, oder durch Verseifen) von dem zurückbleibenden gereinigten und nunmehr hochprocentigen Anthracen getrennt werden.Process for the production of high-percentage anthracene and mixtures containing anthracene, consisting of dividing these into solid or liquid fats (oils) and those to be obtained from them Entries fatty and oleic acids, whereupon the bodies accompanying the anthracene iri Go to solution and by mechanical means (by filtration and pressing or by extraction with petroleum and other suitable liquids, or by saponification) of the remaining purified and now high-percentage anthracene are separated.

KAISERLICHESIMPERIAL PATENTAMT,PATENT OFFICE, PATENTSCHRIFTPATENT LETTERING KLASSE 22: Farbstoffe, Firnisse, Lacke.CLASS 22: dyes, varnishes, lacquers. Patentirt im Deutschen Reiche vom 19. Januar 1886 ab.Patented in the German Empire on January 19, 1886. 100 kg Roh - Anthracen werden in 150 kg Oelsäure, welche auf 110 bis 1200 C. erwärmt wird, unter beständigem Rühren eingetragen, bis sich nahezu alles gelöst hat.' Man läfst erkalten. Es scheidet sich das vorhandene Anthracen in krystallinischer Form nebst relativ geringen Mengen verwandter Körper ab. Die Oelsäure, welche den gröfsten Theil der Verunreinigungen in Lösung hält, wird durch Filtriren, Centrifugiren und Pressen nahezu völlig entfernt. Die Prefskuchen werden entweder durch Behandeln mit Alkali (Verseifung) oder durch Extraction mittelst Petroleum oder anderer geeigneter Flüssigkeiten von den letzten Spuren anhängenden OeIs befreit. Das in beiden Fällen hinterbleibende gelblich- oder grünlich-weifse, lockere Pulver ist das »gereinigte Anthracen«.100 kg Raw - anthracene are introduced into 150 kg of oleic acid, which is heated to 110 to 120 0 C. with constant stirring, until everything has dissolved almost '. You let it cool down. The existing anthracene is deposited in crystalline form along with relatively small amounts of related bodies. The oleic acid, which keeps the greater part of the impurities in solution, is almost completely removed by filtration, centrifugation, and pressing. The prefabricated cakes are freed from the last traces of adhering oils either by treatment with alkali (saponification) or by extraction with petroleum or other suitable liquids. The yellowish or greenish-white, loose powder that remains in both cases is the "purified anthracene". Wie die Oelsäure verhalten sich die anderen Fettsäuren, die Fette und OeIe oder Gemische derselben.The other fatty acids, fats and oils or mixtures, behave like oleic acid the same. Das Erwärmen ist nicht unbedingt nothwendig bei flüssigen Oelsäuren oder Oelen oder Gemischen, wohl aber bei den bei gewöhnlicher Temperatur festen Fettsäuren, Fetten u. s. w.Heating is not absolutely necessary in the case of liquid oleic acids or oils or mixtures, but certainly in the case of fatty acids and fats that are solid at ordinary temperature u. s. w. Die anzuwendenden Mengenverhältnisse von Roh-Anthracen und Oelsäuren u. s. w. werden variirt je nach Gehalt und Beschaffenheit des Roh-Anthracens.The proportions of crude anthracene and oleic acids to be used, etc. varies depending on the content and nature of the raw anthracene. Die Oelsäure u. s. w. kann, ohne gereinigt zu werden, mehrere Male verwendet werden.The oleic acid and the like can be used several times without being purified. Bei Anwendung von festen Fetten, Fettsäuren «u. s. w. erhält man Gemische, welche bei gewöhnlicher Temperatur erstarren. Die genannten Fette, Fettsäuren u. s. w. werden in diesem Falle entfernt durch Extraction mit Petroleum oder anderen geeigneten Flüssigkeiten, oder durch Verseifung. Das Zurückbleibende ist das gereinigte Anthracen.When using solid fats, fatty acids «u. s. w. one obtains mixtures which with ordinary Freeze temperature. The mentioned fats, fatty acids and so on are used in in this case removed by extraction with petroleum or other suitable liquids, or by saponification. What remains is the purified anthracene. Die Methoden der Verseifung und Extraction, der Fette u. s. w. sind die allgemein bekannten.The methods of saponification and extraction, of fats, and so on, are the generally known.
