| abstract | 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 10-300 mg KOH/g) of olefinically unsaturated compounds including 0.5-15 mole-% OH compound(s) and 85-99.5 mole-% ethylene. Lubricity additive for fuel oil contains: (A) 10-95 wt.% oil-soluble amphiphilic aliphatic or aromatic amide or (thio)carboxylic compound(s) of formula R1>[C(O)XR2>]y (I) and/or imine or (thio)ether compound(s) of formula R1>XR2> (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 10-300 mg KOH/g, comprising units of (B.1) 0.5-15 mole-% olefinically unsaturated compound(s) with free OH group(s), (B.2) 85-95.5 mole-% ethylene and (B.3) 0-20 mole-% comonomer(s) selected from (meth)acrylic acid and esters, vinyl esters and ethers and alkenes. R1>1-50 carbon (C) (hydroxy)alkyl, alkenyl or aryl; X : NH, NR3>, O or S; y : 1, 2, 3 or 4; R2>hydrogen (H) or 2-10 C hydroxyalkyl; R3>N, 2-10 C hydroxyalkyl and/or 1-20 C alkyl; or XR2>NR4>1>R4>2>; R4>1>-(R4>3>-NR4>4>)m-R4>5>-; R4>2>-(R4>3>-NR4>4>)n-R4>5>; R4>3>2-10 C alkylene; R4>4>H, methyl, 2-20 C alkyl, R1>-CO- or alkoxy; R4>5>H or R1>-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. |
