COMPOSCIION DE DESTILADO MEDIO DE PETROLEO QUE COMPRENDE UNA PROPORCION MAYOR DE DESTILADO MEDIO DE PETROLEO Y UNA PROPORCION MENOR, SUFICIENTE PARA LIMITAR LA VELOCIDAD DE SEDIMENTACION DE LAS PARAFINAS CONTENIDAS EN DICHO DESTILADO MEDIO, DE UN ADITIVO QUE CONSISTE EN UN PRODUCTO QUE RESULTA DE LA REACCION DE AL MENOS UN COMPUESTO DICARBOXILICO ALIFATICO Y DE AL MENOS UN COMPUESTO CON FUNCION AMINA PRIMARIA QUE RESPONDE A LA FORMULA GENERAL (I), DONDE R1 REPRESENTA UN RADICAL ALIFATICO SATURADO MONOVALENTE, Z SE ELIGE ENTRE LOS GRUPOS-NR''- EN LOS QUE R'' REPRESENTA UN ATOMO DE HIDROGENO O UN RADICAL ALIFATICO SATURADO MONOVALENTE, N ES UN NUMERO ENTERO DE 2 A 4, M ES UN NUMERO ENTERO DE 1 A 4; UTILIZANDOSE DICHO COMPUESTO DE FUNCION PRIMARIA EN UNA PROPORCION DE 0,3 A 0,8 MOL POR MOL DE DICHO COMPUESTO DICARBOXILICO. A middle petroleum distillate composition containing a major proportion of middle petroleum distillate and a minor proportion of an additive in a sufficient amount to limit the settling speed of paraffins contained in said middle distillate. Said additive consists of a product resulting from a reaction between at least one aliphatic dicarboxylic compound and at least one primary amine functional compound of general formula (I), wherein R is a monovalent saturated aliphatic radical, Z is selected from -NR'- groupings in which R' is a hydrogen atom or a monovalent saturated aliphatic radical, n is an integer between 2 and 4, and m is an integer between 1 and 4; said primary amine functional compound being used in a ratio of 0.3-0.8 mols per mol of said dicarboxylic compound.
