Description
Patentirt im Deutschen Reiche vom 29. December 1892 ab.Patented in the German Empire on December 29, 1892.
Werden Naphtadestillationsrückstände, welche zurückbleiben, nachdem die leichten OeIe abdestillirt sind, zur Gewinnung von zähen Schmierölen oder viscosem Vaselin mit Schwefelsäure behandelt, so nehmen sie hierbei, sowie bei der darauffolgenden Bleichung mit Knochenkohle Sauerstoff auf, welcher auf letzterer verdichtet ist, und färben sich dadurch unter theilweiser Oxydation grün.Become naphtha distillation residues which remain after the light oils are distilled off are for the production of viscous lubricating oils or viscous vaseline with sulfuric acid treated, so take them here, as well as during the subsequent bleaching with charcoal Oxygen, which is compressed on the latter, and are thereby partly colored Oxidation green.
Um eine Bleichung zu erzielen, wird die Knochenkohle oder das Vaselin und Schmieröl mit Aethyl- oder Methylalkohol, Oelsäure, trocknenden Oelen, Aldehyden oder Ketonen, die in reinem oder in rohem Zustande angewendet werden können, behandelt. Dies wird so ausgeführt, dafs man obige Körper entweder den betreffenden Mineralölen bei der Filtration zusetzt oder in der Weise auf die Knochenkohle vor der Bleichung einwirken läfst, dafs man sie in flüssigem oder dampfförmigem Zustande bis zur erfolgten Reduction mit dieser in Berührung läfst.To achieve a bleaching effect, the bone char or the petroleum jelly and lubricating oil with ethyl or methyl alcohol, oleic acid, drying oils, aldehydes or ketones, the can be used in the pure or in the raw state. This is done so that the above bodies are either added to the mineral oils concerned during the filtration or let it act on the charcoal before bleaching in such a way that one can they in liquid or vapor state in contact with the latter until the reduction has taken place running.
Patenτ-Anspruch:Patenτ claim:
Verfahren zum Bleichen von durch den activen Sauerstoff der Knochenkohle sich grün färbenden Mineralölen, gekennzeichnet durch die Anwendung von Aethyl- oder Methylalkohol, Aldehyden, Ketonen, Oelsäure, trocknenden Oelen zur Absorption des Sauerstoffes der Knochenkohle bei oder vor der Behandlung der Mineralöle mit der Kohle.Process for bleaching green by the active oxygen of the charcoal coloring mineral oils, characterized by the use of ethyl or methyl alcohol, Aldehydes, ketones, oleic acid, drying oils for the absorption of the oxygen of the charcoal during or before the treatment of mineral oils with coal.
