Abstract:
An additive for lubricant or fuel, comprising at least one member selected from substituted hydroxy aromatic ester derivatives represented by general formulae (I) and (II), (wherein R1 through R5 represent each an organic group having six or more carbon atoms; a, b, d, e, k and m represent each 1 to 3; c, f, g, i and j represent each 0 to 3; h represents 0 to 4, provided f+g=1 to 3 and h+i=1 to 6); a lubricant or fuel additive composition containing the same; and a lubricant or fuel composition containing the same. The additive is suitable as an ashless cleaning agent that is excellent in high-temperature stability and can substitute for metallic cleaning agents. The lubricant or fuel composition containing the same is suitable as an internal-combustion engine lubricant or fuel capable of coping with future severe exhaust gas regulation.

Abstract:
An environmental friendly light hydrocarbon fuel for vehicles comprises: (1) 100 parts by weight of light hydrocarbon, (2) 4-60 parts by weight of aromatic hydrocarbon, (3) 0-20 parts by weight of leadless antiknock agent, (4) 0-0.2 parts by weight of cationic fluorocarbon surfactant, (5) 0.001-2 parts by weight of surface active grade raising agent. The surface active grade raising agent is a mixture of a compound of formula (7) and any one of the compounds of formulas (1-6), or a mixture of a compound of formula (7), any one of the compounds of formulas (1-6) and one or more of the compounds of formulas (8-10), wherein: (1) CFSON(CH)CHOP (O)(OH); (2) CFSON(CH)CHOP (O)(ONa); (3) CFSON(CH)CHCHOP(O)(OH); (4) CFSON(CH)CHCHOP(O)(ONa); (5) CFSON(CH)CHCHOP(O)(OH); (6) CFSON(CH)CHCHOP(O)(ONa); (7) CHCONH(CH)NHCOCH; (8) CFSONHCHCH; (9) CFSOK; (10) CFSON(CH). The fuel has a heat value greater than or equal to 42000KJ/kg, high self ignition point, reasonable distribution of distillation range and high combustion rate, which is a saving, environmental friendly and low-cost substitutive fuel for automobiles.
Abstract:
An overbased magnesium composition deposit control additive for residual fuel oils and turbine fuels is an overbased magnesium sulfonate, carboxylate or phanate or mixtures thereof containing at least 14 % and upwards to about 18 % by weight of magnesium and containing a succinic anhydride and lower carboxylic acid co-promoter reaction product. The additive when added to fuel oils, such as residual fuel oils containing high asphaltenes, reduces, if not eliminates, magnesium/asphaltene deposits or sediment and the consequential plugging of filters. The additive also reduces, if not eliminates, vanadium caused corrosion in the turbine. The invention is also the process for preparing the overbased composition or deposit control additive, wherein the overbasing reaction incorporates the combination of a lower carboxylic acid, preferably acetic acid and a succinic anhydride, preferably dodecenyl succinic anhydride (DDSA), as the co-promoter.
