The invention provides a fuel additive compound represented by the general formula (I): wherein n is zero or an integer from 1 to 20 and in each succinic acid moiety one of R1 and R3 is a C3-C80 internal olefin moiety, and the other of R1 and R3 is hydrogen, and R2 is a linking group, preferably the residue of a polyhydroxy alcohol. Additive compositions containing such compounds have low viscosity and are useful in increasing the lubricity of middle distillate fuels.
La présente invention concerne un composé d'additif de carburant représenté par la formule générale (I). Dans cette formule n est zéro ou un entier compris entre 1 et 20 et dans chaque fraction d'acide succinique un élément parmi R1 et R3 est une fraction d'oléfine interne en C3-C80 et l'autre élément parmi R1 and R3 est hydrogène. Cette invention concerne aussi des compositions d'additif contenant ces composés possédant une faible viscosité et qui convienne pour augmenter la lubricité de carburants de distillat médian.
