L'invention a trait à un procédé de fabrication par extraction, de produits raffinés à partir d'huiles grasses ou minérales, ainsi qae de produits de distillation, de cracking, d'hydrogénation et d'hydrogénation destructive
On a découvert que des agents d'extraction adéquats dans ce procédé de raffinage sont des hydrocarbures dans lesquels an groape nitro oa nitrile a été introduit, On a decouvert en qutre que les termes inférieurs des hydrocar- bares, par exemple le nitrométhane et l'acéto-nitrile sont très actifs, et aassi quebien que la sélectivité est ré- daite, en augmentant le nombre d'atomes carbone,, la proprie- té dissolvante est considérablement accrue, 9 de sorte.

Ain- si, une bonne séparation avec l'aide de nitrobenzol et de benzonitrile n'est obtenue que dans le cas d'huile de cylindre lourde. ON s'est aperça en outre de ce que l'intro- duction simultanée d'autresgroupes est possible dans une me- sure limitée.
Ainsi, par exemple, le méthylrhodanure est

Afin d'améliorer la propriété dissolvante des termes intérieures de agents d'extraction suivant l'invention, dans l'extraction d'hydrocarbures lourds, on ,peut ajouter an dilaant convenablement choisi, tel que le benzol oa un autre hydrocarbure aromatique ou an éther, cependant qu'on peut aussi employer des mélanges des agents d'extaaction.

It proceeds for the manufacture of refined products "
The invention relates to a process for the manufacture by extraction of products refined from fatty or mineral oils, as well as products of distillation, cracking, hydrogenation and destructive hydrogenation.
It has been found that suitable extractants in this refining process are hydrocarbons into which nitro or nitrile has been introduced. aceto-nitrile are very active, and therefore, although the selectivity is reduced, by increasing the number of carbon atoms, the solvent property is considerably increased, 9 so.
that these sabstanes are particularly suitable for the treatment of larger oils and the like. Thus, good separation with the aid of nitrobenzol and benzonitrile is only obtained in the case of heavy cylinder oil. It has also been realized that the simultaneous introduction of other groups is possible to a limited extent.
So, for example, methylrhodanide is
<Desc / Clms Page number 2>
suitable as a selective solvent. However, in the in-
EMI2.1
troduction, the polar character of the moleal should be maintained as much as possible. In order to improve the dissolving property of the internal terms of extracting agents according to the invention, in the extraction of heavy hydrocarbons, one can add an appropriately chosen dilaant, such as benzol or another aromatic hydrocarbon or an ether. , however, mixtures of the extaactants can also be employed.
The advantages of the substances to be employed according to the invention, with respect to that which is known for this purpose, are

It shows their selectivity, which only slightly detects even at higher temperatures, their relatively high stability and their low boiling point, whereby they can be easily recovered.
Example 1.
From a labrifying oil refined according to the Edeleana process, an extract containing 75% of sulphonable constituents is obtained with nitromethane at 20 ° C.
If the extraction is carried out at a temperature of 100 C

10 grams of 1.5155 nasal labrifying mile and containing gâ% of tallow constituents, are extracted at 28.0 with 80 grams of mitromethano.
After having removed the nitromethane by distillation, one obtains c.60 grams of extract with nD- 1.60
Example III.
100 cc of labrifying oil previously refined using the Edeleana process are treated with 200 cc of propionitrile; about 15% of a highly aromatic product is then extracted and an excellent olive oil remains.
