Definitions

  • This invention relates to lubricating oil compositions. Particularly, it relates to lubricants containing an alkaline earth metal salt of a low molecular weight carboxylic acid and a metal phosphate.
  • Alkaline earth metal salts of C to C fatty acids are useful in lubricating oil compositions for improving the extreme pressure properties and anti-wear properties of the lubricant.
  • certain metal phosphates e.g. trisodium phosphate
  • these phosphates serve to prolong the effectiveness of conventional antioxidants by neutralizing the acidic products which result from oxidation degradation of the oil, thereby preventing these acidic materials from further catalyzing the decomposition of the oil.
  • the low molecular weight carboxylates useful in this invention are those alkaline earth metal (e.g. calcium strontium, magnesium or barium) salts of a C to a C fatty acid (e.g. acetic, propionic, butyric acid, etc.).
  • alkaline earth metal e.g. calcium strontium, magnesium or barium
  • These metal carboxylates are best prepared in situ in the lubricating oil by neutralization of the appropriate acid or acid anhydride with a metal base, e.g. calcium hydroxide.
  • a metal base e.g. calcium hydroxide
  • the preferred carboxylate is calcium acetate, in either an anhydrous form or in the form of a monohydrate. If the calcium acetate is formed by neutralizing acetic acid with calcium hydroxide at a temperature between about 200 to 300 F. the monohydrate will result. Heating above 300 F. results in anhydrous calcium acetate.
  • the phosphate materials which may be used in preparing the compositions of the invention include the alkali metal (e.g. sodium and lithium) and the alkaline earth metal (e.g. calcium, barium, magnesium) salts of phosphoric acid, i.e. ortho, meta and pyrophosphoric acid.
  • Preferred salts are those of orthophosphoric acid such as tricalcium orthophosphate, monocalcium dihydrogen orthophosphate, trisodium orthophosphate and disodium hydrogen orthophosphate.
  • the lubricating oil used in the compositions of the invention may be a mineral lubricating oil, a synthetic lubricating oil, or mixtures thereof.
  • Synthetic lubricating oils which may be used include esters of dicarboxylic acids (e.g. di-2-ethylhexyl sebacate); esters of glycols (e.g. C Oxo acid diester of tetraethylene glycol); complex esters (e.g. the complex ester formed by reacting one mole of sebacic acid With two moles of tetraethylene glycol and two moles of 2-ethyl-hexanoic acid); formals, silicones, carbonates, polyglycols and other synthetic lubricating oils known in the art.
  • esters of dicarboxylic acids e.g. di-2-ethylhexyl sebacate

  • Such esters are prepared from C to C alkanols reacted with C to C alkanedioic acids; or C to C glycols reacted with C to C alkanoic acids.
  • Preferred esters are those prepared from alkanedioic acids and Oxo alcohols.
  • the Oxo alcohols are isomeric mixtures of branched chain primary alkanols produced by the reaction of an olefin with hydrogen and carbon monoxide in the presence of a cobalt catalyst to form a mixture of aldehydes, which aldehydes are then hydrogenated to form the OX0 alcohol.

  • This additive combination in turn will generally comprise about 1.0 to 3.0, preferably 1.0 to 2.5 molar proportions of the carboxylate per molar propor tion of the phosphate. In terms of weight proportions, this will roughly correspond to about 1.3 parts by Weight of carboxylate per about one part by weight of phosphate.
  • the oil composition may also contain other additives.
  • additives include viscosity index improvers such as polyisobutylene; corrosion inhibitors such as sorbitan monooleate; pour depressants; dyes;detergents and the like.
  • the phosphate and carboxylate stably suspend each other in oil so that no salt precipitation occurs.
  • the oilsalt system is completely anhydrous, a small amount of the oil Will tend to separate from the main mass upon prolonged storage. This is not a serious problem since upon mixing a homogeneous mass is readily obtained. However, it does represent a slight marketing deterent. It has been further found that this can be inhibited by Patented Dec. 13, 1960 various surface active agents.
  • One such type of surface active agents are copolymers of ethylene glycol and propylene glycol which are commercially available under the trade-name of- Pluronics. These materials havev where a and c are integers of value 2 to 150, and b is an integer of to 170.
  • the molecular weight may vary considerably but generally is between 1,000 and 20,000, e.g. 1,000 to 10,000.

  • the ratio of the ethylene oxide groups to the propylene oxide groups in the Pluronic materials vary between about 3/1 to 1/3.
  • Pluronics L 62 analysis showed a ratio of about 1.15 moles of ethylene oxide per mole of propylene oxide.
  • the ratio of these two alkylene oxide groups is not critical for the present invention since operable materials will include ethylene or propylene polyglycols per se.
  • Another useful surface active agent includes N,N- polyalkyleneoxy disubstituted alkyl amine such as Ethomeen T/25 which has the formula:
  • Duomeen T dioleate which has the structure:
  • alkyl group is derived from tallow.
  • Other surface active agents which may be used are described in my copending patent application Ser. No. 692,041, filed on October 24, 1957. Generally, about 0.05 to about 2.0 wt. percent based on the weight of total composition of surface active agent will be sufficient to prevent oil separation or bleeding under even the worst adverse conditions.

  • EXAMPLE III-B A sample of the product of III-A was heated to 320 F. in order to completely dehydrate the product and form anhydrous calcium acetate. The composition was then homogenized in a Gaulin homogenizer operating at 5000 p.s.i.
  • Example IV EXAMPLE V The product of Example IV was cut back with additional mineral lubricating oil after which the blended product was passed through a Gaulin homogenizer operating at 5,000 psi.

Also, no discoloration of the oil occurred during these oven tests, thus indicating that there was no serious oxidation degradation of the mineral oil.
  • Examples IV, V and VI illustrate compositions further containing a minor amount of a polyglycol .type surface active agent. Example VI did not show the slight oil separation that had occurred in Example III-B during the oven test. This improvement was due to the presence of the small amount of Pluronics L-62.
