Abstract: Disclosed are phosphate ester base fluids and aircraft hydraulic fluids containing a novel combination of phosphate ester components. The disclosed aircraft hydraulic fluids contain from about 30 to about 45 weight percent, based on the total weight of the fluid, of tri-iso-butyl phosphate; from about 30 to about 45 weight percent, based on the total weight of the fluid, of tri-n-butyl phosphate; from about 10 to about 15 weight percent, based on the total weight of the fluid, of one or more triaryl phosphates; and an effective amount of a viscosity index improver, an acid control additive and an erosion inhibitor.

Abstract: A method for introducing a surfactant into an oil bearing formation includes plurality of a micro-slug injections of surfactant. Each micro-slug injection comprises an "on time" in which the surfactant is introduced into the formation and which is based upon the time needed for the surfactant to generate foam in the formation and a "off time" in which surfactant flow is stopped and is based upon the time period for the generated foam to degrade to a predetermined degree in the formation.

Abstract: A method for enhancing the uniformity of steam quality, i.e., steam quality equalization, in a multiple steam injection system having a steam generator, a primary steam header, at least one secondary steam header, a primary steam line connecting the generator to the primary header, at least one secondary steam line connecting the primary header to a secondary steam header, and a plurality of tertiary steam lines connecting the secondary steam header to a tertiary steam header or one of a plurality of steam injections wells involves the introduction of a surfactant at a point subsequent to the steam generator. The surfactant preferably includes those alkyl aromatic sulfonates which include at least one alkyl group comprising 12-30 carbon atoms, more preferably, 20-24 carbon atoms with the preferred concentration of surfactant being about 100 to about 250 ppm, based on the total cold water equivalent of the steam flow.

Abstract: A process for the recovery of oil from a petroleum reservoir by improving steam sweep efficiency during steam-flooding, wherein a foaming agent is added to divert steam to unswept zones and the reservoir is penetrated by at least one injection well and at least one production well, which process comprises injecting steam and a surfactant solution into an injection well, while concurrently and separately injecting an additional amount of liquid water into the injection well; and recovering oil from a production well.

Abstract: A process for the preparation and recovery of m,m'-dinitrobenzophenone and which comprises reacting benzophenone with nitric acid in oleum; adjusting the reaction product to a water content from 12 to 30 weight percent; and extracting the m,m'-dinitrobenzophenone with a chlorinated hydrocarbon solvent.

Abstract: An improved process is disclosed for the preparation of bis(2-haloalkyl) phosphorohalidates. This process comprises the steps of reacting phosphorus trihalide with a stoichiometric excess of alkylene oxide to form tris(2-haloalkyl) phosphite, substantially eliminating the presence of unreacted alkylene oxide in the tris(2-haloalkyl) phosphite, and finally converting it to bis(2-haloalkyl) phosphorohalidate by reaction with halogen.
