Definitions

  • the present invention relates to the use of specific dicarboxylic acid derivatives as solubilizers for homogenizing additive concentrates which comprise cold flow improvers, detergent additives, inert organic solvents and if appropriate cetane number improvers.
  • the invention further relates to additive concentrates suitable for additizing fuel oil compositions which consist predominantly of a middle distillate fuel which boils in the range of 120-500 0 C and/or a renewable fuel, said additive concentrates having the ingredients mentioned.
  • additive concentrates which, as well as cold flow improvers which are typically added to the diesel fuels and heating oils in the mineral oil refineries, also comprise detergent additives and cetane number improvers which form the main constituents of so-called diesel performance packages, there are frequent occurrences - especially at temperatures significantly below 20 0 C - of flaky precipitates which cannot be filtered off; attempted filtration can lead to filter conglutination.
  • additive concentrates are, however, generally slightly to highly turbid.
  • the presence of additionally used organic solvents in the additive concentrates cannot prevent such flaky precipitates or turbidities.
  • the flaky precipitates which usually at first remain more or less dispersed in the solution, can subsequently lead to severe sedimentation or to gel formation in the additive concentrate.
  • R 1 denotes a hydrocarbylene radical having from 1 to 12 carbon atoms or a hydrocarbylene radical which has from 2 to 12 carbon atoms, is interrupted by one or more heteroatoms selected from the group of O, S and N, and may in each case bear one or more functional groups selected from the group of OH, OR 3 , NH 2 , NHR 4 , NR 4 R 5 , COOH, COOR 7 , CONHR 4 and CONR 4 R 5 , where amino groups may also be present in protonated form and carboxylic acid groups also in deprotonated form,
  • X is OH, OR 3 , NH 2 , NHR 4 or NR 4 R 5 , where, in the case that X together with the adjacent carbonyl group is a carboxylic acid radical, this radical is present in deprotonated form and the accompanying cation may be a hydrocarbyl- substituted ammonium cation selected from the group of [HsNR 8 J + , [H 2 NR 8 R 9 J + and [HNR 8 R 9 R 1Q ] + ,
  • Y is O, S, NH or NR 6 , or, in the case that X is NH 2 or NHR 4 , is a chemical bond to X with formation of an imide structure,
  • R 2 to R 10 are each independently hydrocarbyl radicals having from 1 to 30 carbon atoms
  • R 2 , R 3 , R 4 , R 5 , R 6 and R 7 radicals has at least 4 carbon atoms
  • additive concentrates suitable for additizing fuel oil compositions which consist predominantly of a middle distillate fuel which boils in the range of 120-500 0 C and/or a renewable fuel, said additive concentrates comprising
  • the additive concentrates mentioned preferably additionally comprise
  • solubilizers I used according to the invention also occurs in principle in additive concentrates which do not comprise any cetane number improver.
  • solubilizers I used in accordance with the invention are used to homogenize additive concentrates which comprise (A) from 1 to 50% by weight, especially from 2 to 40% by weight, in particular from 3 to 20% by weight, of at least one cold flow improver,
  • (B) from 0.5 to 40% by weight, preferably from 0.7 to 20% by weight, especially from 1 to 12% by weight, in particular from 1.5 to 7% by weight, of at least one detergent additive,
  • (C) from 1 to 60% by weight, especially from 3 to 50% by weight, in particular from 5 to 40% by weight, of an inert organic solvent or of a mixture of such solvents and
  • (D) from 0 to 80% by weight, especially from 25 to 75% by weight, in particular from 40 to 70% by weight, of at least one cetane number improver.
  • the additive concentrates mentioned may additionally comprise further ingredients, in which case the sum of all ingredients adds up to 100% by weight.
  • homogenization shall be understood to mean the prevention or the elimination of the flaky precipitates or turbidities described above in the additive concentrates.
  • the specific dicarboxylic acid derivatives of the general formula I used as solubilizers in the present invention are known from WO 2007/131894. They are recommended there as cold stabilization enhancers in fuel oil compositions which comprise customary cold flow improvers and detergent additives, in low dosages - specifically from 1 to 2000 ppm by weight, based on the fuel oil composition. Corresponding additive concentrates or technical problems to be solved with such additive concentrates are not addressed in WO 2007/131894.
  • EP-A 807 676 discloses low-sulfur middle distillate fuels which, to improve their lubricity, comprise carboxamides, for example also amides of C3- to C4o-dicarboxylic acids, cold flow improvers and ashless dispersants.
