Petroleum middle distillate composition containing a substance for limiting the paraffin sedimentation rate

摘要: A middle petroleum distillate composition containing a major proportion of and minor an additive in sufficient amount to limit the settling speed paraffins contained said distillate. Said consists product resulting from reaction between at least one aliphatic dicarboxylic compound primary amine functional general formula (I), wherein R 1 is monovalent saturated radical, Z selected —NR′— groupings which R′ hydrogen atom or n integer 2 4, m I 4; being used ratio 0.3-0.8 mols per mol compound. —Z(CH )—NH H  (I)
