Verfahren zur Reinigung von niedrigsiedenden Mineralöldestillaten.

<Desc/Clms Page number 2>
Rohbenzins, u. zw. bei dem angenommenen Rohprodukt mit einer Anfangssiedetemperatur von 350 C um ungefähr 100. Sodann destillieren in der bekannten Weise Leicht-, Mittel-und Sehwerbenzinanteile über, die einen höchst angenehmen Geruch besitzen und nicht nachdunkeln. Wenn die Temperatur von etwa 1800 erreicht ist, steigt der Siedepunkt jäh um etwa 70 an. Es destillieren nun sehr geringe Anteile von paraffinum liquidum-artigen und schliesslieh von. chmierölartigen Fraktionen über, die gleichfalls geruchlos und geschmacklos sind.
Man gewinnt aus 100 Teilen Rohbenzin 85-90 Teile gereinigter Benzinfraktionen und nur gegen 5 Teile der hochsiedenden Fraktion. Arbeitet man hingegen bei Temperaturen von über 35 , so werden weitaus grössere Anteile der Benzine in spezifisch schwerere, höher siedende Produkte übergeführt.
Die entstehende Lösung von Aluminiumchlorid in den sich ausscheidende dunklen Ölen kann bis zu zehnmal mit ungeminderter Wirksamkeit zur Reinigung von leicht siedenden Destillaten wiederverwendet werden.
Das beschriebene Verfahren ist nicht nur für die Reinigung von Krackbenzin anwendbar, sondern es können auch Benzine, die bei der normalen Destillation des Erdöles gewonnen werden, in der angegebenen Weise raffiniert werden. Es werden dabei besonders auch die höher siedenden Fraktionen, Sehwerbenzin und Lackbenzin, von den übelriechenden, ungesättigten Verbindungen befreit, ohne dass eine nachherige Redestillation erforderlich wäre.

Raw gasoline, etc. between the assumed crude product with an initial boiling temperature of 350 ° C. by about 100. Then light, medium and commercial spirit components distill over in the known manner, which have a very pleasant smell and do not darken. When the temperature reaches around 1800, the boiling point rises sharply by around 70. Very small amounts of paraffinum liquidum-like and finally from distill now. oil-like fractions, which are also odorless and tasteless.
From 100 parts of raw gasoline, 85-90 parts of purified gasoline fractions and only 5 parts of the high-boiling fraction are obtained. On the other hand, if you work at temperatures above 35, much larger proportions of the gasoline are converted into specifically heavier, higher-boiling products.
The resulting solution of aluminum chloride in the dark oils that precipitate can be reused up to ten times with undiminished effectiveness for cleaning low-boiling distillates.
The process described is not only applicable for the purification of cracked gasoline, but gasoline, which are obtained in the normal distillation of petroleum, can also be refined in the manner indicated. In particular, the higher-boiling fractions, sehwerbenzin and white spirit, are freed from the bad-smelling, unsaturated compounds without a subsequent redistillation being necessary.
