Abstract: Water-based hydraulic fluids and metalworking lubricants are disclosed which are thickened with a polyether polyol having a molecular weight of about 1000 to about 75,000 modified with an alpha-olefin epoxide having about 12 to about 18 carbon atoms.

Abstract: Tertiary, cyclic, bridgehead amines are disclosed as useful corrosion inhibitors for metals in contact with aqueous alkaline liquids. The disclosed amines have been found to be strongly resistant to thermal decomposition, to chemical attack, and to nitrosation. The use of these corrosion inhibitors is particularly desirable in aqueous alcohol compositions useful as a heat exchange liquid in the cooling systems of an internal combustion engine wherein said aqueous solutions are ethylene glycol-based compositions. The disclosed amines are useful under alkaline conditions alone or in combination with conventional corrosion inhibitors such as water-soluble metal salts of tolyltriazole and phosphoric acid, alkali metal nitrites and nitrates, and alkali metal phosphates.

The minimum amount of catalyst is automatically provided to the polymerization mixture by adding a first member of a redox pair to the polymerization mixture and intimately combining a second member of the redox pair catalyst with an organic polymer capable of forming a colloidal dispersion in an aqueous medium and adding this intimate mixture to the mixture of water, acrylamide monomer, and a first member of the redox pair catalyst.

Abstract: Crude oil and gas production wells, which no longer produce oil or gas utilizing conventional primary and secondary means of recovery, can be returned to production by treatment comprising addition of an aqueous solution of certain phosphate ester surfactants followed by successive treatment with a hydrocarbon. Increased production also can be obtained in low-producing oil and gas wells by similar treatment with certain phosphate ester surfactants. Subsequent to treatment of a producer well, the phosphate ester surfactant is forced into the formation utilizing a hydrocarbon and said surfactant and hydrocarbon mixture is allowed to remain in the producing well, for an effective period of time ranging from not less than 24 hours to one month. Thereafter, pumping and/or conventional fluid drive means are then utilized to recover oil or gas from the subterranean oil or gas formation.
