FUEL ADDITIVES

摘要

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.
