Definitions

  • US 5,094,666 describes a three or more component additive comprising an ethylene backbone polymer, and two nitrogen compounds.
  • EP 0308176 describes an additive for adding to a fuel oil which is a fused mixture of a paraffin wax and a flow improver.
  • the flow improver may be a copolymer of an ester of fumaric acid and a vinyl ester.
  • the additive may be in the form of solid slabs or blocks to aid effective distribution and handling.
  • Suitable dicarboxylic acid anhydrides for use in preparing the copolymer include maleic anhydride, itaconic anhydride and citraconic anhydride, and the like, with maleic anhydride being preferred.
  • Suitable dicarboxylic acids for use in preparing the copolymer include maleic acid, fumaric acid, itaconic acid, and the like, with maleic acid being preferred.
  • Preferred alcohols include those alcohols having 6 to 14 carbon atoms, especially the branched alkanols, with 2-ethylhexanol and isodecyl alcohol being particularly preferred. Mixed esters can also be used.
  • the invention still further provides an additive concentrate comprising a solvent or carrier liquid miscible with fuel oil and the three additive system comprising the copolymer or homopolymer and at least two additional cold flow additives as described above.
  • a concentrate comprising the additive dispersed in carrier liquid is convenient as a means of incorporating the additive.
  • the concentrates of the present invention are convenient as a means for incorporating the additives into bulk oil such as distillate fuel, which incorporation may be done by methods known in the art.
  • the concentrates may also contain other additives as required and preferably contain from 3 to 75 wt.%, more preferably 3 to 60 wt.%, most preferably 10 to 50 wt.% of the additives preferably in solution in oil.
  • carrier liquid are organic solvents including hydrocarbon solvents, for example petroleum fractions such as naphtha, kerosene, diesel and heater oil; aromatic hydrocarbons such as aromatic fractions, e.g.
  • Polyoxyalkylene diesters, diethers, ether/esters and mixtures thereof are suitable as additives, diesters being preferred for use in narrow boiling distillates, when minor amounts of monoethers and monoesters (which are often formed in the manufacturing process) may also be present. It is preferred that a major amount of the dialkyl compound be present.
  • stearic or behenic diesters of polyethylene glycol, polypropylene glycol or polyethylene/ polypropylene glycol mixtures are preferred.
  • Table 6 reports data for the test reported in Table 3 for copolymers of the invention have been post-reacted with amines.
