Patent

CA 2281635

The invention concerns an additive for motive fuel additive, in particular with low sulphur content not more than 500 ppm, consisting for the most part of a combination comprising 5 to 95 wt. % of a glycerol monoester R1-C(O)-O-CH2-CHO-CH2OH or R1-C(O)-O-CH(CH2OH)2, R1 being an alkyl chain containing 8 to 60 carbon atoms, or a monocyclic or polycyclic group comprising 8 to 60 carbon atoms, and from 5 to 95 wt. % of a compound of formula R2-C(O)-X, R2 being an alkyl chain containing 8 to 24 carbon atoms, or a monocyclic or polycyclic group comprising 8 to 60 carbon atoms, and X being selected among (i) the groups OR0, R0 being a hydrocarbon radical comprising 1 to 8 carbon atoms, optionally substituted by one or several esters; and (ii) the groups derived from primary or secondary amines and alkanolamines with aliphatic hydrocarbon chain, comprising 1 to 18 carbon atoms.

Additif d'onctuosité pour les carburants moteurs, notamment à faible teneur en soufre inférieure ou égale à 500 ppm, composé majoritairement d'une combinaison comprenant de 5 à 95 % en poids d'un monoester de glycerol R1-C(O)-O-CH2-CHO-CH2OH ou R1-C(O)-O-CH(CH2OH)2, R1 étant une chaîne alkyle comprenant de 8 à 24 atomes de carbone, ou un groupement mono ou polycyclique comprenant de 8 à 60 atomes de carbone, et de 5 à 95 % en poids d'un composé de formule R2-C(O)-X, R2 étant une chaîne alkyle comprenant de 8 à 24 atomes de carbone, ou un groupement mono ou polycyclique comprenant de 8 à 60 atomes de carbone, et X étant choisi parmi (i) les groupements OR0, R0 étant un reste hydrocarboné comprenant de 1 à 8 atomes de carbone, éventuellement substitué par un ou plusieurs groupements esters, et (ii) les groupements dérivant d'amines primaires ou secondaires et d'alcanolamines de chaîne hydrocarbonée aliphatique, comprenant de 1 à 18 atomes de carbone.
