The invention relates to low-temperature-stabilized additives for fuel oils having a sulfur content of up 0.05% by weight, comprising fatty acid mixtures of A1) from 1 to 99% by weight of at least one saturated mono- or dicarboxylic acid having from 6 to 50 carbon atoms, A2) from 1 to 99% by weight of at least one unsaturated mono- or dicarboxylic acid having from 6 to 50 carbon atoms, and B) at least one polar nitrogen-containing compound which is effective as paraffin dispersant in middle distillates, in an amount of from 0.01 to 90% by weight, based on the total weight of A1), A2) and B), and to the use of said mixtures for improving the lubrication properties of low-sulfur middle distillates.
L'invention concerne des additifs stabilisés à faible température pour des mazouts ayant une teneur maximale en soufre de 0,05 % en poids, comprenant des mélanges d'acides gras : A1) 1 à 99 % en poids d'au moins un acide saturé monocarboxylique ou dicarboxylique ayant entre 6 et 50 atomes de carbone, A2) 1 à 99 % en poids d'au moins un acide non saturé monocarboxylique ou dicarboxylique ayant entre 6 et 50 atomes de carbone et B) au moins un composé de nitrogène polaire, un agent dispersant efficace de paraffine dans des distillats moyens, pour une quantité de 0,01 à 90 % en poids, selon le poids total de A1), A2) et B). Lesdits mélanges ont pour but d'améliorer les propriétés lubrifiantes de distillats moyens à basse teneur en soufre.
