Patent ID: 8097570

Claim:
A lubricating, anti-corrosive and antistatic composition for hydrocarbon mixtures comprising: a) at least a compound A of Formula (I) below: in which R 1 and R 2 are hydrogen or a linear or branched alkyl group of 1-40 carbon atoms, comprising optionally at least one double bond, R 1 and R 2 together being able to form an aromatic or aliphatic ring of 5-6 carbon atoms, said ring being capable of substitution by one to three linear or branched alkyl group(s) of 1-40 carbon atoms, in which R 1 and R 2 cannot be hydrogen at the same time, and in which R 3 and R 4 , identical or different, are chosen from the OH groups, in which R 3 and R 4 cannot be the OH group simultaneously, or deriving from a linear or branched monol or polyol group containing 1-20 carbon atoms having a functionality of 2 to 5 inclusive; b) and at least a compound B corresponding to a fatty acid of 16-24 carbon atoms, unsaturated or not, optionally in a mixture with a carboxylic acid comprising at least aromatic and/or olefinic polycycle or ring and/or their ester, amide or corresponding amine salts derivatives, taken alone or in a mixture.
