Abstract (en)

[origin: EP1134274A2] Lubricity additive for fuel oil contains: (A) 10-95 wt.% oil-soluble amphiphilic aliphatic or aromatic amide, (thio)carboxylic, imine and/or (thio)ether compound(s); and (B) 5-90 wt.% copolymer (weight average molecular weight 500-100000 g/mole; hydroxyl (OH) number 10-350 mg KOH/g) of olefinically unsaturated compounds including 5-80 mole-% OH compound(s) and 20-95 mole-% compound(s) with an NOTLESS 6 carbon hydrocarbon chain. Lubricity additive for fuel oil contains: (A) 10-95 wt.% oil-soluble amphiphilic aliphatic or aromatic amide or (thio)carboxylic compound(s) of formula R<1)<C(O)XR<2>)y (I) and/or imine or (thio)ether compound(s) of formula R<1>XR<2> (II); and (B) 5-90 wt.% copolymer(s) with a weight average molecular weight (Mw) of 500-100000 g/mole and hydroxyl (OH) number of 10-350 mg KOH/g, comprising units of (B.1) 5-80 mole % olefinically unsaturated compound(s) with free OH group(s), (B.2) 20-95 mole-% olefinically unsaturated compound(s) with a hydrocarbon chain containing NOTLESS 6 carbon (C) atoms and (B.3) 0-40 mole % comonomer(s) selected from (meth)acrylic acid and esters, vinyl esters and ethers and alkenes. R<1> = 1-50 C (hydroxy)alkyl, alkenyl or aryl; X = NH, NR<3>, O or S; y = 1, 2, 3 or 4; R<2> = hydrogen (H) or 2-10 C hydroxyalkyl; R<3> = N, 2-10 C hydroxyalkyl and/or 1-20 C alkyl; or XR<2> = NR<41>R<42>; R<41> = -(R<43>-NR<44>)m-R<45>; R<42> = -(R<43>-NR<44>)n-R<45>; R<43> = 2-10 C alkylene; R<44> = H, methyl, 2-10 C alkyl, R<1>-CO- or alkoxy; R<45> = H or R<1>-CO-; m, n = 0-20. Independent claims are also included for: (a) fuel oil, comprising a middle distillate containing ≤ 0.05 wt.% sulfur, and 0.001-2 wt.% of the additive; and (b) mixtures of the additive with flow enhancers, comb polymers and/or paraffin dispersants.
