NEW NITROGEN ADDITIVES FOR USE AS A BLOOD POINT REDUCTION AGENTS OF MEDIUM DISTILLATES, IN PARTICULAR GASOLES, AND THE COMPOSITIONS OF MEDIUM DISTILLATES CONTAINING SUCH ADDITIVES, ARE DESCRIBED. THE ADDITIVES CONSIDERED RESULT FROM THE CONDENSATION OF COMPOUNDS CONTAINING A PRIMARY AMINE FUNCTION, SUCH AS FAT AMINES, POLYAMINES DERIVED FROM FATTY AMINES, POLYAMINES CONTAINING A PRIMARY AMINE FUNCTION AND A TERTIARY AMINE FUNCTION, AMINOALERSCOOLS OF ETHES OR ETHES. OILY, ON TERPOLYMERS FORMED BY THE COPOLYMERIZATION A OF OLEFINS-A, B OF MALEIC COMPOUNDS (DIACIDS, DIESTERS OR ANHYDRIDES) AND C OF ACRYLATES OR ALKYL METHACRYLATES. A SENSITIVE EFFECT OF LOWERING THE TROUBLE POINT OF THE MEDIUM DISTILLATES TREATED WITH THESE ADDITIVES IS OBSERVED FOR CONCENTRATIONS OF 0.001 TO 1 BY WEIGHT OF ADDITIVE. THESE ADDITIVES ALSO IMPROVE THE LIMIT TEMPERATURE OF FILTRABILITY AND THE OUTPUT POINT OF THE MEDIUM DISTILLATES; THEY ALSO DELAY THE SEDIMENTATION OF FORMED PARAFFINS AND DECREASE CORROSION OF METAL SURFACES IN CONTACT WITH MEDIUM DISTILLATES. |
