MIXTURE OF POLAR OIL-SOLUBLE NITROGEN COMPOUNDS AND OIL-SOLUBLE ALIPHATIC COMPOUNDS FOR LOWERING THE CLOUD POINT IN MIDDLE DISTILLATE FUELS

MIXTURE OF POLAR OIL-SOLUBLE NITROGEN COMPOUNDS AND OIL-SOLUBLE ALIPHATIC COMPOUNDS FOR LOWERING THE CLOUD POINT IN MIDDLE DISTILLATE FUELS

The use of a mixture comprising (A) 5 to 95% by weight of at least one oil-soluble polar nitrogen compound which can interact with paraffin crystals in middle distillate fuels under cold conditions, and (B) 5 to 95% by weight of at least one oil-soluble aliphatic compound with an alkyl or alkenyl ch...

Zusammenfassung:The use of a mixture comprising (A) 5 to 95% by weight of at least one oil-soluble polar nitrogen compound which can interact with paraffin crystals in middle distillate fuels under cold conditions, and (B) 5 to 95% by weight of at least one oil-soluble aliphatic compound with an alkyl or alkenyl chain having at least 8 carbon atoms, obtainable from aliphatic mono- or dicarboxylic acids having 4 to 300 carbon atoms or derivatives thereof with mono- or polyamines or with alcohols, for lowering the cloud point in middle distillate fuels which, before the addition of additives, have a CP of −8.0° C. or lower by at least 1.5° C. compared to the unadditized middle distillate fuel at a dosage of the mixture of 50 to 300 ppm by weight, with no simultaneous deterioration in the response behavior for the lowering of the cold filter plugging point on addition of cold flow improvers.
