PRODUIT POUR'LE FRACTIONNEMENT D'HUILES MINERALES.
11 a été trouvé que des solutions aqueuses diluées de phospha- tes d'amines aliphatiques avec plus de six atomes de carbone, les amines pouvant, le cas échéant, encore avoir été combinées avec de 1?oxyde d'éthy- lène, sont appropriées pour le fractionnement d'émulsions d'huiles minéra- les, c'est-à-dire pour la séparation du produit en émulsiono
Le procédé est expliqué par les exemples ci-dessous
Exemple 1 ;
10 parties en poids d'une solution aqueuse à 1% d'une stéarylamine, ou d'un mélange d'amines correspondant aux acides gras de coco, traitée avec 5-30 Mol d'oxyde déthylène, qui a été transformée avec de l'acide phosphorique en le sel primaire, sont combinés avec 100 parties en poids d'une émulsion aqueuse d'une huile brute, agités pendant 5 minutes, et chauffées au bain-marie pendant 2-8 heures à 70-80 o Au cours de cette période se produit une déshydratation pratiquement complétée
Exmeple 2 ;
On prépare une solution aqueuse à 1% d'un phospha- te qui a été obtenu à partir de stéarylamine, transformée avec 5-30 Mol. d'oxyde d'éthylébne, et neutralisation partielle subséquente avec 1 Mol de soude caustique pour 1 Mol de phosphateo 10 parties en poids de cette so- lution sont ajoutées à 100 parties en poids d'une solution aqueuse d'huile brute et le mélange est chauffé à environ 70 . 0 ,L'émulsion est pratiquement complètement séparée après environ 5 heureso Au lieu du phosphate préparé à l'aide de stéarylamine, on peut utiliser, de la même manière, un phospha- te préparé, de façon analogue, à partir du mélange d'amines correspondant aux acides gras de coco.
Les phosphates utilisés peuvent être modifiés dans une grande mesure par le choix de l'amine. La préparation de phosphates de ces amines est décrite dans la demande de brevet,déposée en même temps que la présen- te, pour "Procédé pour la préparation d'aminophosphates".

PRODUCT FOR THE FRACTIONATION OF MINERAL OILS.
It has been found that dilute aqueous solutions of phosphates of aliphatic amines with more than six carbon atoms, the amines possibly still having been combined with ethylene oxide, are suitable. for the fractionation of mineral oil emulsions, that is to say for the separation of the product into an emulsion
The process is explained by the examples below
Example 1;
10 parts by weight of a 1% aqueous solution of a stearylamine, or a mixture of amines corresponding to coconut fatty acids, treated with 5-30 Mol of ethylene oxide, which has been converted with l phosphoric acid in the primary salt, are combined with 100 parts by weight of an aqueous emulsion of a crude oil, stirred for 5 minutes, and heated in a water bath for 2-8 hours at 70-80 ° C. this period occurs almost complete dehydration
Example 2;
Preparing a 1% aqueous solution of a phosphate which was obtained from stearylamine, transformed with 5-30 Mol. of ethylene oxide, and subsequent partial neutralization with 1 mol of caustic soda per 1 mol of phosphateo 10 parts by weight of this solution are added to 100 parts by weight of an aqueous solution of crude oil and the mixture is heated to about 70. 0. The emulsion is practically completely separated after about 5 hours. Instead of the phosphate prepared with the aid of stearylamine, a phosphate prepared in the same way from the mixture of stearylamine can be used in the same way. amines corresponding to coconut fatty acids.
The phosphates used can be modified to a great extent by the choice of the amine. The preparation of phosphates of these amines is described in the patent application, filed together with the present, for "Process for the preparation of aminophosphates".
