Abstract: A water-soluble ionically-charged random copolymer of acrylamide and an alkaline or alkali metal 3-acrylamido-3-methylbutanoate having an average molecular weight of greater than about 50,000 has been found to maintain unusually stable and effective viscosities in the presence of salts such as NaCl and CaCl.sub.2 when added to water in minor amounts, thus making it a highly effective mobility control agent for secondary and tertiary oil recovery methods. Also within the scope of the invention are terpolymers which additionally contain olefinically unsaturated monomers such as acrylic acid or sodium acrylate.

Abstract: This invention relates to a low energy process for the solvent extraction of aromatic hydrocarbons from hydrocarbon streams containing the same, using as the solvent N-cyclohexyl-2-pyrrolidone together with small amounts of water. This solvent may be recovered from the aromatics by cooling the aromatic/solvent mixture, and adding water, whereby separation takes place without distillation. The solvent may then be separated from the water by heating the solvent/water mixture.

Abstract: An inert, water-immiscible inert organic liquid having gas transport properties, water and a suitable emulsifying agent are formed into a stable gel by emulsifying a mixture of the same, concentrating the emulsion to form a gel phase and a liquid phase, and separating the two phases. The resulting gel can be used as an ointment or cosmetic for skin irritations or wounds, or as a coating in industrial applications where extended contact of a surface with a gas, such as oxygen, is desired. Fluorocarbons or low viscosity silicone oils are suitable organic liquid components of the gels.

Abstract: Equimolar amounts of phenol and formaldehyde may be prepared from oxygen and toluene. The catalytic oxidation of toluene, when carried out in the presence of acetic anhydride, forms phenyl acetate and methylene diacetate.
