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 co mpounds which are capable of sufficiently dispersing in fuels paraffin cryst als that build up under cold conditions, b) oil-soluble acid amides from pol yamines with 2 to 1000 nitrogen atoms and C8 to C30 fatty acids or fatty aci d-analog compounds containing free carboxyl groups, and c) oil-soluble react ion products from .alpha.,.beta.-dicarboxylic acids with 4 to 300 carbon ato ms or the derivatives thereof and primary alkyl amines. The mixture accordin g to the invention is suitable as a paraffin dispersant in fuels, especially in fuels having a biodiesel content.
