Isopropanol

CAS RN: 67-63-0

Major Uses

Both oil base and water base fracturing fluids are being used in the fracturing industry. Water base, which includes alcohol-water mixtures and low strength acids, make up the majority of treating fluids. The common chemicals added to these fluids are polymers for viscosity development, crosslinkers for viscosity enhancement, pH control chemicals, gel breakers for polymer degradation following the treatment, surfactants, clay stabilizers, alcohol, bactericides, fluid loss additives and friction reducer. /Hydraulic fracturing/
Hydraulic fracturing uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground. These cracks in the rock then allow oil and natural gas to flow, increasing resource production. ... Chemical Name: Isopropanol; Chemical Purpose: Product stabilizer and/or winterizing agent; Product Function: Corrosion inhibitor.

Chemical: feedstock in the production of acetone; manufacture of methyl isobutyl ketone, methyl isobutyl carbinol, isopropylamine, and isopropyl acetate.
Used to prepared hydrogen peroxide by alcohol auto-oxidation process
Solvent: oils, gums, waxes, resins, alkaloids, cements, primers, varnishes, paints, printing inks, cosmetics (eg lotions, perfumes, shampoos, skin cleansers, nail polishes, makeup removers, deodorants, body oils, and skin lotions); aerosol formulations (hair sprays, floor detergents, show polishes, insecticides, burn ointments, window cleaners, waxes and polishes, paints, automotive products, insect repellents, flea and tick spray, air refreshers, disinfectants, veterinary wound and pinkeye spray, first-aid spray, foot fungicide, and fabric-wrinkle remover).
Medical: antiseptic; disinfectant for home, hospital, and industry; rubbing alcohol; medicinal liniments; tinctures of green soap; scalp tonics; tincture of mercurophen; pharmaceuticals (eg, local anesthetics, tincture of iodine, and bathing solutions for surgical sutures and dressings).
Used in gasoline to prevent icing (i.e. depresses the freezing point) of water or surfactants
Isopropanol is used in hydraulic fracturing fluids as a surfactant to increase the viscosity of the fracture fluid; specific compounds in fracturing fluids vary, but a typical fluid (on average) contains 99.51% water and sand with the isopropanol component at 0.085%
