Definitions

  • the present invention relates to the field of greases, and more particularly to improvements in low temperature greases.
  • low temperature greases In the usual methods of manufacturing low temperature greases, low boiling mineral oil fractions with resultant low flash points and low viscosities are compounded with metallic soaps to form plastic masses, or semi-solid grease compositions. It has been observed that the torque necessary to turn a bearing lubricated by grease is directly proportional to the viscosity of the oil used in the grease at the particular temperature.
  • esters of allphatic dibasic acids may be substituted for low boiling mineral oil fractions in the production of low temperature greases.
  • esters possess unusually high boiling points and resulting low vapor'pressures at ambient temperatures, high viscosity indices, or low viscosity-temperature coeflicient, extremely low pour points and are relatively stable chemically.
  • aliphatic dicarboxylic acids suitable for the preparation of the esters used in making the grease compositions of the present invention there may be mentioned malonic, succinic, isosuccinic, glutaric, ethyl maonic, pyro tartaric, adipic, pimelic, su-
  • R is a bivalent aliphatic hydrocarbon radical
  • R is a bivalent aliphatic hydrocarbon radical such as methylene, polymethylene, ethylidene, propylidene, methyl dimethylene, butenylidene and the like
  • R1 and R2 are hydrocarbon radicals such as branched chain alkyl, alkaryi and cyclo alkyl radicals of which secondary butyl, benzyl, cyclo hexanol and secondary octyl phenyl are representative: Isobutyl, 2-ethyl hexyi sebacate is an example of a mixed ester.
  • esters may contain additional constituents or functional groups such as Cl, Br, NHa, NHR, NRIRI, CHO, CO, SH, SR, RSSR, ROR, ROMetal,
  • the esters may be made by any of the methods for producing esters known to the art.
  • a suitable low temperature grease composition may comprise di-2-ethyl hexyl sebacate and disecondary butyl sebacate; with from 6 to 30% of a soap of a metal selected from the group consisting of alkali and alkaline earth metals together with a stabilizer consisting of an amphoteric metal compound, specifically an oxide carbonate or soap of zinc or aluminum.
  • the composition may consist of a major proportion, for example 65% or more, of disecondary butyl adipate and di-isopropyl sebacate with 6 to 30% of soap and stabilizer as recited above.
  • One suitable method consists of reacting the alcohol with the acid at elevated temperatures in the presence of an esterification catalyst such as sulfuric acid, sulfosalicyclic acid, etc. tion is facilitated by a continuous removal of water formed during the reaction by azeotropic distillation with a solvent such as benzene, toluene, etc. or by passing inert gas through the reaction mixture to remove water of reaction.
  • an esterification catalyst such as sulfuric acid, sulfosalicyclic acid, etc.
  • tion is facilitated by a continuous removal of water formed during the reaction by azeotropic distillation with a solvent such as benzene, toluene, etc. or by passing inert gas through the reaction mixture to remove water of reaction.
  • the product is washed with dilute alkali to remove the catalyst and any traces of unreacted acid and if necessary is heated under reduced pressure with or without blowing with an inert gas to remove any unreacted alcohol or other low boiling material.
  • the product can be claytreated, and it is desirable although not absolutely necessary, that the finished ester have a neutralization number not higher than about 0.2 mg.
  • KOH per gram of ester to obtain suitable stability-to oxidation, since free acids left in the finished material can catalyze oxidation of the product, particularly in the presence of materials such as copper or brass at elevated temperatures.
  • Typical esters together with some of their more The reac- 3 slhgrlaiflcant properties are given in the following completely melted. The grease was then rapidly cooledbyrunningitover adrumchiller. Itia Tm: I
  • esters of this type possess ideal properties with regard to pour point, viscosity and viscositytemperature characteristics, flash and boiling points necessary to minimize evaporation, making valuable lubricants for use as low temperature reases.
  • the soap In making the greases of the present'invention it is preferred to make the soap first, as for instance tallow, stearic acid or hydrogenated fish oil acids are reacted with alkali until an indicator shows the alkali to be present in slight excess.
  • the soap thus formed is dried and if desired it may be powdered to facilitate solution in the ester.
  • the soap may in case of lithium, calcium, magnesium, or aluminum be prepared by precipitation from water by pro- .cedures well established in the art.
  • the required amount of soap is then added to the ester and the mixture heated to from 380-400 F. until the soap is completely melted in the ester.
  • any of the alkalis or alkaline earth metals such as sodium or calcium, magnesium, strontium, lithium being preferred, may be used for neutralizing or saponifying the soap stock.
  • the soap stock any of the ordinary higher fatty acids or the fats from which they are derived such as stearic acid. oleic, erucic, lauric, palmitic acid, tallow, lard oil. animal fats, eta, although it is preferred to use the acid derived from hydrogenated fish oil, may be used to form the soaps with which to make the grease.
  • the greases of the present invention will contain in general alkali or alkaline earth soaps ranging from 6-30% of the total composition, 65-93.5% of the ester or mixture of several esters. and .5-5% of a stabilizer.
  • the use of a stabilizer smooths out the texture of the grease and-further aids in the actual production of the grease.
  • the oxides, carbonates, or soaps of metals forming amphoteric oxides such as the soaps of zinc, tin and aluminum, have been found to be very beneficial in their use as stabilizers, particularly in the case of greases containing free alkali. Mixtures of these soaps may also be used, a particularly effective combination being 5% aluminum stearate and .5% zinc naphthenate.
  • Grease represented by Examples 4 and 5 have excellent low temperature properties and also due to the high boiling esters used in their preparation are exceptionally stable at extremely high ground temperatures.
