MIXTURE FROM POLAR OIL-SOLUBLE NITROGEN COMPOUNDS AND ACID AMIDES AS PARAFFIN DISPERSANT FOR FUELS

摘要

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.
