Procédé de purification des huiles végétales afin de les transformer en halles de graissage.
La présente invention a pour objet un procédé de purification des huiles végétales,afin de les transformer en huiles de graissage.Conformément à cette invention, les huiles employées, et en particulier l'huile de ricin, sont mélangées et brassées vigoureusement pendant un certain temps, à une lessive faiblement alcaline, Puis on précipite par une lessive saline les acides gras libres, ainsi que les gommes, parenchymes, etc.. qui se trouvent saponifiés, on laisse décanter, puis on évacue les lessives qui contiennent toutes les impuretés, ainsi que les matières colorantes de l'huile.
On lave l'huile avec de l'eau ordinaire, mais la température de cell e-ci ne devra jamais être inférieure à 15 centigrade, Ce lavage a pour but de dissoudre les savons contenant les
<Desc/Clms Page number 2>
gommes, parenchymes, etc..On laisse décanter et on soutire l'eau savonneuse. On répète ce lavage jusqu'au moment où l'eau tort claire. L'huile est ensuite filtrée et centrifugée, pour séparer les dernières traces d'eau. L'opération de raffinage est terminée.
Les huiles obtenues par ce procédé sont en grandes parties décolorées et absolument neutres. Les parenchymes qui, par leur oxydation, sont la cause de l'acidité des huiles, se trouvent précipités et éliminés. L'huile reste donc stable et ne reprend aucune acidité, même en pays chauds, même au bout d'un très long temps. Elle peut servir au graissage le plus délicat, et en particulier des moteurs d'aviation, d'automobiles, etc.. Elles ne produisent aucune mauvaise odeur en brûlant, elles ne gomment pas et ne lais- sent aucun résidu x soli de .

Process for purifying vegetable oils in order to transform them into lubrication halls.
The present invention relates to a process for purifying vegetable oils in order to transform them into lubricating oils. According to this invention, the oils used, and in particular castor oil, are mixed and stirred vigorously for a certain time. , with a weakly alkaline lye, Then the free fatty acids are precipitated by a saline lye, as well as the gums, parenchyma, etc. which are saponified, one leaves to settle, then one evacuates the lye which contains all the impurities, thus than the coloring matters of the oil.
The oil is washed with ordinary water, but the temperature of the latter should never be less than 15 centigrade. The purpose of this washing is to dissolve the soaps containing the
<Desc / Clms Page number 2>
gums, parenchyma, etc. Leave to settle and draw off the soapy water. This washing is repeated until the water is mistakenly clear. The oil is then filtered and centrifuged, to separate the last traces of water. The refining operation is complete.
The oils obtained by this process are largely discolored and absolutely neutral. The parenchyma which, by their oxidation, are the cause of the acidity of the oils, are precipitated and eliminated. The oil therefore remains stable and does not regain any acidity, even in hot countries, even after a very long time. It can be used for the most delicate lubrication, and in particular of aircraft engines, automobiles, etc. They do not produce any bad odor when burning, they do not gum up and do not leave any solid residue.
