Definitions

  • This invention relates to a thickener component based on an aluminium carboxylate compound and to an aluminium complex grease made therefrom with addition of a base liquid.
  • Aluminium complex greases have been known. They essentially comprise a mineral-oil base liquid and a thickener system containing one or more aluminium carboxylate compounds.
  • the aluminium carboxylate compound is obtained by reacting a fatty acid and/or an aromatic carboxylic acid with an aluminium alcoholate derivative.
  • the industrially used aluminium alcoholates comprise aluminium isopropoxylate and tri-oxy-aluminium-triisopropoxide. In theory, the reaction proceeds as shown hereinbelow:
  • Aluminium complex greases are distinguished by a high dropping point, good conveyance and water resistance, and low separation of oil.
  • the term ‘more effective’ shall mean that the grease exhibits better lubricating properties than conventional aluminium complex greases.
  • the thickener component employed for making said aluminium complex greases be storable and marketable as such, thus enabling the grease manufacturer to produce the thickener-containing grease himself.
  • hydrolysable aluminium compounds refers to aluminium compounds that are capable of forming aluminium-oxygen bonds by the action of proton-donating compounds, such as water or organic acids.
  • hydrolysable aluminium compounds are aluminium alcoholate- or aluminium-oxo-alcoholate compounds with the alcoholate group preferably being a C 2 - to C 4 -alcohol, particularly isopropanolate.
  • the carboxylic acids can be branched or unbranched aliphatic monocarboxylic acids of the type R 1 —COOH, wherein R 1 represents a C 10 - to C 40 -radical, preferably a C 14 - to C 24 -radical, or a C 16 - to C 24 -radical.
  • Carboxylic acid derivatives as used herein are defined as compounds which are capable of forming in combination with said aluminium compounds the aluminium-carboxylate bonds that would likewise be obtained when using the corresponding acids. Examples thereof include the anhydrides, acid chlorides, or amides of the aforesaid carboxylic acids.
  • Ester compounds as used herein particularly refer to compounds which may be formed by reaction of the alcohols/alcoholates present in the reaction mixture with the carboxylic acids/carboxylate residues.
  • the thickener component is prepared by reaction, preferably about equimolar reaction, i.e. about 1 mole of monocarboxylic acid per mole of aluminium atoms in the compound, of a hydrolysable aluminium compound with one or more of the abovementioned carboxylic acid(s) or carboxylic acid derivative(s) at a temperature not exceeding 145° C., most preferably 135° C., with a temperature profile most preferably increasing gradually by at least 20° C. during a period of at least 90 minutes being ensured. It is preferred that the hydrolysable aluminium compound be placed in the vessel first.
  • reaction be carried out in a base liquid and the volatile compound released during the reaction, e.g. alcohol, be withdrawn from the equilibrium.
  • volatile compound released during the reaction e.g. alcohol
  • thickener as used herein is defined as a compound or mixture of compounds prepared from the thickener component, which thickener can be produced by reacting the thickener component with aromatic or cyclic monocarboxylic acids of the type R 2 —COOH, wherein R 2 represents a C 6 - to C 16 -radical, or with the derivatives thereof.
  • aromatic or cyclic monocarboxylic acids of the type R 2 —COOH, wherein R 2 represents a C 6 - to C 16 -radical, or with the derivatives thereof.
  • Said (aromatic or cyclic) carboxylic acid derivatives are defined as described hereinabove.
  • aromatic monocarboxylic acid is defined as a carboxylic acid which has at least one benzene ring or condensed benzene ring and, in addition, may comprise aliphatic hydrocarbn radicals as well.
  • compounds such as C 6 H 5 —CH 2 —CH 2 —COOH or CH 3 —CH 2 —C 6 H 4 —COOH are explicitly included herein.
  • the thickener as a constituent of the aluminium complex grease is produced by compounding the thickener component, optionally taken up in additional base liquid, with the aromatic or cyclic monocarboxylic acid.
  • the production process of the invention yields a raw material (thickener component) with a low ester content for making the real thickener that keeps its low ester content even upon storage.
  • the aluminium complex greases of the invention also comprise a base liquid which is a hydrocarbon compound and/or a synthetic oil added to the overall composition in quantities of from 30 to 98 weight percent, preferably 60 to 95 weight percent.
  • the hydrocarbon compound can be a paraffin-base or naphthenic mineral oil, a polyalphaolefin, or a white oil.
  • Further synthetic oils which are suitable as base liquid include fatty acid esters based on mono- or multifunctional fatty acids having a chain length of from 8 to 24 carbon atoms and mono- or polyhydric alcohols. Additional constituents of the aluminium complex greases of the invention may be typical additives. Table 1 presents examples of suitable additives.
  • the thickener components of the invention are useful as raw materials for producing thickeners included in aluminium complex greases exhibiting improved lubricating properties. They are preferably employed in high-temperature applications for which high dropping points are especially desirable, in central lubricators, and/or for lubricating machinery used for example for producing or processing foodstuffs.
  • the thickener components as well contain 20 to 80 weight percent, most preferably 30 to 70 weight percent of the base liquid described hereinabove.
  • Example 4 presents a high ester concentration, whereas the ester concentration in Example 5 (comparative example) is too high.
  • the measurements were made on a thickener component having an aluminium content of 4.1 weight percent.
  • the solvent in the aluminium-containing thickener component is identical with the base oil.
  • the starting material is aluminium isopropanolate.
  • the aliphatic monocarboxylic acid employed herein is a technical-grade stearic acid mixture.
  • the released 2-propanol is removed overhead (head temperature max. 85° C.).
  • the bottom temperature is gradually increased to 127° C. during this period. Once the bottom temperature reaches 127° C., the pressure is reduced to 200 hPa during 20 minutes and the remainder of the low-boiling 2-propanol is drawn off.
  • a distillate comprised of 3.623 moles (217.7 g) of 2-propanol is removed from the reaction and the mixture (123.6 g).
  • the product, oxo-aluminium-stearate is obtained after purification and filtration.
  • the total residence time of the product at 127° C. is 30 minutes (until end of vacuum phase). Filtration is performed at approx. 120° C. using a 60- ⁇ m sieve.
