The instant invention is directed to a method for producing a lubricating base stock having a preselected oxidative stability comprising the steps of: (a) separating, into a plurality of fractions based on molecular shape, a hydroisomerized hydrocarbon wax, (b) collecting the fractions of step (a) which have the preselected oxidative stability for use as a lubricating base stock, wherein the fractions to be collected are determined by measuring the oxidative stability of each of said fractions of said plurality of fractions to determine which fractions have said preselected oxidative stability. The invention is also directed to an improved lubricating base oil and a formulated lubricating composition using said lubricating base oil.

L'invention porte sur un procédé de production d'une huile de base pour lubrifiants présentant une stabilité prédéfinie vis à vis de l'oxydation comportant les étapes suivantes: (a) séparation en plusieurs fractions en fonction de la forme des molécules d'une cire d'hydrocarbures hydroisomérisés; (b) recueil des fractions de la phase (a) présentant la stabilité prédéfinie vis à vis de l'oxydation qui constituent l'huile de base pour lubrifiants, la sélection desdites fractions se faisant par mesure de la stabilité de chacune des différentes fractions pour déterminer celle présentant la stabilité voulue. L'invention porte également sur l'huile de base améliorée ainsi obtenue et sur la formule d'une composition lubrifiante la contenant.
