  Verfahren zur Reinigung von niedrigsiedenden   Mineralöldestillaten.   
 EMI1.1 
 

 <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.

  Process for cleaning low-boiling mineral oil distillates.
 EMI1.1
 

 <Desc / Clms Page number 2>

 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.
