摘要： PROBLEM TO BE SOLVED: To obtain a fuel oil additive which, when added to a low-sulfur fuel oil having a specified sulfur content, gives a fuel oil compsn. excellent in lubricity, separation of water, and resistance to emulsification by incorporating a monounsatd. monocarboxylic acid and a diunsatd. monocarboxylic acid in a specified wt. ratio, these acids having each a specified number of carbon atoms, into the same. SOLUTION: This additive contains a 12-22C monounsatd. monocarboxylic acid (pref. oleic acid) and a 12-22C diunsatd. monocarboxylic acid (pref. linolic acid) in a wt. ratio of (40/60)-(90/10), pref. (45/55)-(80/20), still pref. (50/50) (70/30). Pref., the sum of the amts. of these acids accounts for 50 wt.% or higher of the additive. The additive is added to a low-sulfur fuel oil having a sulfur content of 0. 2 mass % or lower, in an amt. of the additive of 20-500 ppm based on the fuel oil. If necessary, a pour-point depressant (e.g. an ethylene-vinyl acetate copolymer) is incorporated into the additive.

摘要： PURPOSE: To provide a fuel oil composition resistant to the crystallization at low temperature and having improved fluidity, by compounding a petroleum fuel oil containing a pour-point depressant with a higher amine modification product of a copolymer of an α,β-unsaturated dicarboxylic acid anhydride and a lower monoolefin.
CONSTITUTION: The objective fuel oil composition is prepared by compounding a petroleum fuel oil containing usually 5W5,000ppm of a pour-point depressant with usually 10W10,000ppm of a higher amine modification product of a copolymer of an α,β-unsaturated dicarboxylic acid anhydride and a lower monoolefin (usually having a molecular weight of 1,000W500,000). The above modification product is usually those containing (A) 20W80mol% of a monomer unit having higher alkyl group and bonded through an acid imide bond or acid amide bond, (B) 0W 60mol% of an α,β-unsaturated dicarboxylic acid anhydride monomer unit and (C) 20W80mol% of a lower monoolefin monomer unit.

摘要： PURPOSE:An additive that contains an ethylene-ethylenically unsaturated ester copolymer containing a specific amount of methyl-terminated side chains, thus improving the flowability at low temperature and the flowing characteristics of petroleum fuel. CONSTITUTION:The additive contains an ethylene-ethylenically unsaturated ester copolymer containing 10-50wt% of an ethylenically unsaturated ester and having a molecular weight of 1,000-5,000, preferably an ethylene-vinyl acetate copolymer, further bearing 6-15 methyl-terminated side chains per 100 methylene groups in addition to the methyl groups in the unsaturated ester monomer of the copolymer. The copolymer is produced by copolymerization of ethylene and an ethylenically unsaturated ester monomer in the presence of a polymerization regulator such as propylene. EFFECT:The additive acts as a suitable pour-point depressant for light oil, kerosine or heavy oil boiling at 130-145 deg.C.
