Patent number: 5258137Abstract: A foam-fluid composition for use in foam fracture applications and foam slurry transport comprises a thickening amount of a viscoelastic surfactant composition, a functionally effective amount of a surfactant composition capable of forming a foam, and an aqueous liquid. Foam-fluid formulations are easily prepared, reusable, shear stable, easily pumped and form stable foams over a wide temperature range and exhibit high viscosities even at relatively high temperatures.Type: GrantFiled: March 9, 1992Date of Patent: November 2, 1993Assignee: The Dow Chemical CompanyInventors: Jeffrey E. Bonekamp, Gene D. Rose, Donald L. Schmidt, Arthur S. Teot, Edward K. Watkins

Patent number: 4880565Abstract: Shear stable antimisting properties are provided to a wide variety of formulations comprising aqueous liquids through the use of a viscoelastic surfactant which comprises a surfactant compound having a hydrophobic moiety chemically bonded to an ionic, hydrophilic moiety and an electrolyte having a moiety that is capable of associating with the surfactant ion. Optionally, an additional amount of electrolyte can be added to the viscoelastic surfactant to further reduce misting. The viscoelastic surfactant can also be a nonionic surfactant.Type: GrantFiled: April 12, 1985Date of Patent: November 14, 1989Assignee: The Dow Chemical CompanyInventors: Gene D. Rose, Arthur S. Teot, Keith G. Seymour

Patent number: 4806256Abstract: Water-based hydraulic fluids are thickened by admixing the fluid with a viscoelastic surfactant. Viscoelastic surfactants comprise surfactant ions and organic counterions that associate with the hydraulic fluid to form the viscoelastic surfactant. Water-based hydraulic fluids of this invention are highly shear stable and do not experience substantial viscosity loss with an increase in temperature. The hydraulic fluids are capable of providing low amounts of wear in pumping apparatus during use.Type: GrantFiled: January 13, 1987Date of Patent: February 21, 1989Assignee: The Dow Chemical CompanyInventors: Gene D. Rose, Arthur S. Teot

Patent number: 4800036Abstract: Bleach compositions, such as aqueous sodium hypochlorite formulations, are thickened by admixing the composition with a viscoelastic surfactant. Visco-elastic surfactants comprise surfactant ions and organic counterions that associate in the bleach composition to form the viscoelastic surfactant. Thickened bleach compositions of this invention exhibit bleach stability, phase stability, and viscosity stability for acceptably long periods of time. The thickened bleach compositions can be employed as nonmisting sprays and streams which will stick to vertical surfaces without substantial dripping and can be applied to various substrates using a dispensing device.Type: GrantFiled: December 8, 1986Date of Patent: January 24, 1989Assignee: The Dow Chemical CompanyInventors: Gene D. Rose, Arthur S. Teot, Kenneth L. Foster

Patent number: 4790958Abstract: Onium species of nitrogen, phosphorus or sulfur are useful to precipitate ferric ion, existing as tetrahaloferrate anion, from strong haloacid solutions. The precipitants are useful in the field of well acidizing, because tetrahaloferrate anion attacks polymeric and viscoelastic surfactant thickeners used to thicken haloacid solutions.Type: GrantFiled: May 18, 1987Date of Patent: December 13, 1988Assignee: The Dow Chemical CompanyInventor: Arthur S. Teot

Patent number: 4735731Abstract: Industrial liquids containing viscoelastic surfactant compositions can be reversibly thickened and broken. For example, a thickened industrial liquid can exhibit good solids carrying capacity, and after the viscosity of the liquid is broken, using techniques such as change in pH, addition of a hydrocarbon, change in temperature, etc., the solids can be easily removed therefrom. Viscosity can be again provided to the industrial liquid without the necessity of adding substantial amounts of additional thickener.Type: GrantFiled: April 14, 1986Date of Patent: April 5, 1988Assignee: The Dow Chemical CompanyInventors: Gene D. Rose, Arthur S. Teot, Peter A. Doty

Patent number: 4725372Abstract: A wellbore service fluid is provided which contains water, a water soluble electrolyte and as a thickening agent at least one of an amine, a salt of an amine, or quaternary ammonium salt which functions to increase the viscosity of the fluid in the presence of said electrolyte.Type: GrantFiled: January 6, 1983Date of Patent: February 16, 1988Assignee: The Dow Chemical CompanyInventors: Arthur S. Teot, Muthyala Ramaiah, Mitchael D. Coffey
-
Patent number: 4615825Abstract: The friction exhibited by a flowing aqueous liquid containing a viscoelastic surfactant can be further reduced by adding to the aqueous liquid an organic electrolyte capable of associating with the surfactant ion of the viscoelastic surfactant. For example, the friction exhibited by an aqueous liquid containing cetyl trimethylammonium salicylate can be further reduced by the addition of sodium salicylate to the liquid. The resulting aqueous liquid systems exhibiting the reduced friction are shear stable and useful in a wide variety of applications.Type: GrantFiled: October 30, 1981Date of Patent: October 7, 1986Assignee: The Dow Chemical CompanyInventors: Arthur S. Teot, Gene D. Rose, Gregory A. Stevens

Patent number: 4585572Abstract: A reversible liquid/solid phase change composition for storing thermal energy. The composition comprises at least one hydrated inorganic salt selected from a salt or mixture of salts that are subject to segregation of its chemical components during repeated freezing and thawing cycles, and a surface active thickening agent in the form of a cationic surfactant and selected from an amine, salts of the amine, or a quaternary ammonium salt of the amine, wherein the thickening agent is present in the hydrated salt in an amount sufficient to form a micelle structure throughout the hydrated salt to prevent such segregation.Type: GrantFiled: October 11, 1983Date of Patent: April 29, 1986Assignee: The Dow Chemical CompanyInventors: George A. Lane, Harold E. Rossow, Arthur S. Teot

Patent number: 4138352Abstract: Detergent compositions of particular value in washing synthetic fabrics, especially polyester, inhibiting the redeposition of soil and imparting antisoil properties are based essentially on a combination of a nonionic surfactant and a hydroxybutylated methylcellulose of low molecular weight and having a relatively high degree of substitution.Type: GrantFiled: February 3, 1978Date of Patent: February 6, 1979Assignee: The Dow Chemical CompanyInventors: Arthur S. Teot, Percy J. Hamlin, Albert B. Savage
