Abstract:
An oil-in-water-in-oil emulsion (O/W/O) comprising a first oil-in-water emulsion dispersed in a second oil, and a method of preparing the same. The O/W/O emulsion can be used as a drive fluid in an enhanced oil recovery process. The O/W/O emulsion of this invention may also be used as a lubricant, and has the beneficial property of being resistant to shear forces.

759,284. Hydraulic fluids. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Jan. 4, 1954 [Jan. 5, 1953], No. 186/54. Class 69 (2). [Also in Group III] An hydraulic fluid comprises a major proportion of an oleaginous liquid ester and minor proportions of an epoxy compound and of an aryl amine containing a plurality of amino-aryl linkages. The epoxy compounds may contain one or more epoxy groups, and may be polymers containing epoxy groups. The arylamines may be diamino diarylalkanes, thiodiarylamines, diarylamines or alkylated phenylene diamines. The oleaginous liquid ester may be an ester of an acid of phosphorus, such as phosphates, phosphonates, phosphinates, diphosphorus compounds and ethers of diphosphorus compounds; an ester of silicic acid; or an ester of a carboxylic acid, such as an ester of mono or polyhydric alcohol with a mono or polybasic acid; or an ester of a silicic, phosphorus or dicarboxylic acid with thia-alcohols or thio-alcohols. Many examples of the epoxy compound, amine and ester are listed. Viscosity index improvers, extreme pressure agents, pour point-depressants and anti-wear agents may also be added to the positions. In examples, compositions are referred to which contain (a) the reaction product of bisphenol and epichlorohydrin (M.W. 300), phenyl-α-naphthylamine, and one of tri-(2- ethyl-hexyl) phosphate, triisoctyl phosphate, bis-(2-ethylhexyl) sebacate, tetra-(2-ethylhexyl) silicate, tetra-(7-methyl 4-thiaoctyl) silicate, or dinonyl-iso octene phosphonate; (b) trioctyl phosphate, di-(N,N 1 -sec-butyl) p-phenylenediamine and poly-(allyl-2, 3-epoxypropyl ether) (M.W. 400); (c) ethylene glycol diester of capric acid, pheno-thiazine and poly-(2,3-epoxypropyl crotonate) (M.W. 350); (d) diphenyl cresyl phosphate, N 1 -N 1 -tetramethyl diaminodiphenyl methane and glycidylphenyl ether; and (e) diphenyloctyl phosphate, bis-(2,3-epoxypropyl) ether and dibenzylamine. Specification 671,408 is referred to.

Abstract:
A process for the preparation of a composition comprising amine-containing phosphate glycerides including: phosphorylating a solution which comprises mixed glycerides that contain fatty acid portions and an amine under conditions which are substantially water-free and under which said phosphorous pentoxide reacts with reactive constituents in said solution to form said amine-containing phosphate glycerides and a lubricating composition comprising a lubricant, the aforesaid composition in an amount which improves the properties of the lubricating composition, and optionally one or more other constituents which improve the properties of the lubricating composition.
Abstract:
A heavy-duty lubricating grease is shown which includes a synthetic fluid base and a thickener system. The heavy-duty grease can be used in both rolling element and journal type rock bit bearings to drill in heavy-duty, high temperature applications, such as in the bearing structures of rock bits used to drill hot subterranean formations.
