Oxidation-stabilized lubricant additives for highly desulfurized fuel oils An additive for improving the lubricity of fuel oils having a maximum sulfur content of 0.035% by weight, comprising A) at least one partial ester composed of a di- or polyhydric alcohol and unsaturated and optionally also saturated fatty acids whose carbon chain lengths are between 8 and 30 carbon atoms, at least 60% of the fatty acid radicals containing at least one double bond, and B) at least one alkylphenol-aldehyde resin, obtainable by the condensation of (i) at least one alkylphenol having at least one C6-C24-alkyl or C6-C24- alkenyl radical and (ii) at least one aldehyde or ketone, to a degree of condensation of between 2 and 50 alkylphenol units.
Additifs lubrifiants rendus résistants à l'oxydation destinés aux mazouts hautement désoufrés. Additif permettant d'accroître le pouvoir lubrifiant des mazouts ayant une teneur en soufre maximale de 0,035 % en poids, renfermant : A) au moins un ester partiel composé d'un alcool di- ou polyhydrique ainsi que d'acides gras insaturés et, de manière facultative, d'acides gras saturés, dont les chaînes carbonées comptent entre 8 et 30 atomes de carbone, au moins 60 % des radicaux d'acides gras comptant au moins une liaison double; B) au moins une résine alkylphénol-aldéhyde, que l'on peut obtenir par condensation i) d'au moins un alkylphénol comportant au moins un radical alkyle en C6 à C24 ou alkényle en C6 à C24 et ii) d'au moins un aldéhyde ou d'une cétone, jusqu'à un degré de condensation se situant entre 2 et 50 unités d'alkylphénol.
