Abstract: In the manufacture of hydraulic fluids comprising water (or a mixture of water and an alcohol or a glycol) thickened with a non-ionic detergent (see Group XXIX), the solubility of the detergent is increased by adding a minor proportion of an anionic or a cationic detergent. Non-ionic detergents referred to are ethers of C4-C110 alkylated or dialkylated phenols, e.g. octylated cresol, with polyhydric alcohols or polymeric glycols such as polyethylene glycol; diethylene glycol mono-oleate; glyceryl mono-oleate; polyoxyalkylene derivatives of fatty acid esters of polyhydric alcohols; esterified polyoxyalkylene derivatives of urea; and condensation products of alkyl phenols with ethylene oxide. Cationic detergents specified are the quaternary ammonium halides such as mono (C10-C20 alkyl) tri (C1-C5 alkyl) ammonium halides, e.g. cetyl trimethyl ammonium bromide; and C10-C20 alkyl pyridinium halides, e.g. cetyl pyridinium bromide. Anionic detergents mentioned are the water-soluble alkali metal salts of sulphonated vegetable oils, e.g. Turkey red oil, or sulphonated alkyl aromatic compounds, e.g. the sodium salt of sulphonated C12 polypropylene benzene or toluene. Alcohols or glycols specified are isopropyl alcohol, ethylene glycol, glycerol and polyglycols.

Abstract: 686,550. Hydraulic fluids. STANDARD OIL DEVELOPMENT CO. Jan. 4, 1951 [Jan. 13, 1950]. No. 881/50. Class 69(ii). A hydraulic fluid is prepared by first blending together a water-soluble glycol or polyglycol and a water-soluble non-gelling polyoxyalkylene derivative of sorbitan mono-oleate and then mixing water with the blend. The polyoxyethylene or polyoxypropylene derivatives of sorbitan mono-oleate are referred to, and glycols mentioned are ethylene and diethylene glycols. From 50-65 volumes of glycol, 50-35 volumes of water, and 5-40 per cent by volume of ester based on the volume of glycol-water mixture, may be used. Anti-foaming agents, for example, straight-chain alcohols and silicones; metal corrosion inhibitors, such as sodium salts of benzoic, succinic and cinnamic acids and rnercaptobenzthiazole, inorganic nitrites and phosphates, salts of amines and inorganic acids, such as nitrous, chromic and phosphoric acids, for example di-isopropylamine nitrite and diethylethanolamine phosphate ; and wear reducing agents such as tributyl phosphate, may also be added. Specifications 618,538 and 673,951 are referred to.

Abstract: An oxidation inhibitor is dissolved in mineral oil before it is refined by treatment with an adsorbent, the oxidation inhibitor being chosen from the following classes, viz. phenols, organic amines, organic nitro compounds and organic sulphur compounds. Mineral oils mentioned are insulating oils and steam turbine lubricating oils, while the adsorbent may be an activated clay, carbon, silica, alumina or silica-magnesia mixture. Specific activated earths mentioned are montmorillonite, attapulgus clay and Florida earth. The insulating oil may be one thickened with petrolatum, wax, rosin, polybutene or polymethyl methacraylate, or such thickeners may be added after refining. Phenolic oxidation inhibitors include phenol, diphenol, naphthols and alkylated phenols such as trialkylated phenols, while the organic amines used as oxidation inhibitors include phenolic amines. Organic sulphur compounds which may be employed as oxidation inhibitors include thio-alcohols, thio-ethers, xanthates and thiphosphates. Oxidation inhibitors for use in the case of insulating oils are preferably those that do not increase the p power factor or reduce the resistivity of the oil, particularly 2, 4, 6 tri-t-butyl phenol, 2, 6 di-t-butyl 4-methyl phenol and 2, 2-bis (31, 51-di-t-butyl 41-hydroxyphenyl) pentane. Additional substances which may be added to the refined oils are rust and corrosion inhibitors (e.g. metal naphthenates or sulphonates, or certain mercapto-substituted aliphatic monocarboxylic acids), anti-foaming agents (e.g. polymeric silicones), wear reducing agents (e.g. organic phosphates and thiophosphates), detergents (e.g. alkaline earth metal salts of alkyl phenyl sulphides) and metal de-activators (e.g. N, N1 disalicylidene 1, 2-diamino propane). In examples, 2, 6-di-t-butyl 4-methyl phenol is dissolved in mineral oil, suitable for use as insulating oil or turbine oil, before it is refined by agitation with montmorillonite or Fuller's earth. Tests are described in which the refined oils of the examples are compared with similar oils which have been adsorbent-refined in the absence of oxidation inhibitors, the latter in some cases being added after refining.

Abstract: A lubricating composition, substantially non-volatile at temperatures below 200 DEG F., comprises a mineral lubricating oil, up to 10 per cent of a mono- and/or di-oleate of pentaerythritol and up to 10 per cent of fatty emulsifying oil or fat. Naphthenic or paraffinic oils may be used. Fatty oils and fats specified are olive oil, neatsfoot oil, hardened sperm oil, shark liver oil, wool fat and blown rapeseed oil. In an example, a composition of 97.875 per cent naphthenic distillate oil, 2 per cent of blown rapeseed oil and 0.125 per cent pentaerythritol mono- or di-oleate is used. Examples are given for comparison of mixtures of a naphthenic distillate oil and (a) pentaerythritol monooleate; (b) olive oil; (c) neatsfoot oil; (d) hardened sperm oil; (e) blown rapeseed oil; (f) shark liver oil; (g) lanoline; (h) sorbitan monolaurate with or without blown rape oil; and (i) glyceryl stearate, with or without blown rape oil. Specification 604,860 is referred to. The Provisional Specification refers to a composition comprising a base oil and a long-chain fatty acid ester of a polyhydroxy alcohol with or without a fatty emulsifying oil.
