CA 2655877
The invention relates to a mixture from: a) polar oil-soluble nitrogen compounds which are capable of sufficiently dispersing in fuels paraffin crystals that build up under cold conditions, b) oil-soluble acid amides from polyamines with 2 to 1000 nitrogen atoms and C8 to C30 fatty acids or fatty acid-analog compounds containing free carboxyl groups, and c) oil-soluble reaction products from .alpha.,.beta.-dicarboxylic acids with 4 to 300 carbon atoms or the derivatives thereof and primary alkyl amines. The mixture according to the invention is suitable as a paraffin dispersant in fuels, especially in fuels having a biodiesel content.
Mélange constitué (a) de composés d'azote polaires oléosolubles qui sont en mesure de disperser suffisamment des cristaux de paraffine précipités par le froid dans des carburants, (b) d'amides d'acides oléosolubles dérivés de polyamines ayant 2 à 1000 atomes d'azote, et d'acides gras C8-C30 ou de composés analogues à des acides gras contenant des groupes carboxyle libres et (c) de produits de réaction oléosolubles dérivés d'acides .alpha.,.beta.-dicarboxyliques ayant 4 à 300 atomes de carbone ou de dérivés et d'alkylamines primaires desdits produits. Ledit mélange est adapté en tant que dispersant de paraffine pour des carburants, en particulier ceux qui contiennent une portion de biodiesel.
