Definitions

  • hydrocarbon lubricating oils are provided with grease-like structures by the dispersal therethrough of colloidal gels of sulfides of metals having a water solubility no greater than 0.0005 g. per 100 cc. H2O at 20 C.
  • outstanding members of the present series of greases comprise those gelled with copper sulfides, since copper sulfides exhibit peculiar oleophilic properties common to sulfides of the hydrogen sulfide group metals as compared with other metallic sulfide compounds.
  • the lubricants are, preferably at least moderately refined but, except. when used. as dielectric compositions, need not behighly. refined; however, highly refined lubricating oils. are equally suitable. While the. principal object, of the present invention has been stated'to .be the production. of grease-like lubricants, another type of composition. contemplated is that of thixotropic gels especially useful. as. cuttingfiuids Qr,,.mo.re particularly. for well-drilling operations. Inthe. latter instance especially, lower molecularweighthydrm carbonfiuids areespeciallydesirable and particularly. thoseinthe kerosene stove. oil .orgas, .oiLboiling; ranges.
