USE OF NITROGEN ADDITIVES AS DISORDERS OF HYDROCARBON MEDIUM DISTILLATE DISORDER POINT AND HYDROCARBON MEDIUM DISTILLATE COMPOSITIONS COMPRISING SUCH ADDITIVES

摘要

DESCRIPTION OF MEDIUM DISTILLATE COMPOSITIONS, IN PARTICULAR GASOLES HAVING IN PARTICULAR THEIR POINT OF DISORDER LOWERED BY THE INTRODUCTION OF NITROGEN ADDITIVES. THE ADDITIVES CONSIDERED RESULT FROM THE CONDENSATION OF FATTY AMINES OR POLYAMINES DERIVED FROM FATTY AMINO ACIDS ON CYCLIC ANHYDRIDES, SUCH AS ANHYDRIDES: MALEIC, ALKYLMALEIC OR ALKENYL-SUCCINIC. / P P A SENSITIVE EFFECT OF LOWERING THE POINT OF DISORDER OF THE MEDIUM DISTILLATES TREATED BY THESE ADDITIVES IS OBSERVED FOR CONCENTRATIONS OF 20G TO 2000G PER TONNE OF MEDIUM DISTILLATE. / P P THESE ADDITIVES ALSO IMPROVE THE TEMPERATURE LIMIT OF FILTRABILITY, DELAY THE SEDIMENTATION OF FORMED PARAFFINS AND INHIBIT THE CORROSION OF METAL SURFACES IN CONTACT WITH DISTILLATES MEANS. / P
