Uses and applications

What the substance is used for, by industry and function

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. ...

Pharmacology

Isopropyl Alcohol is an isomer of propyl alcohol with antibacterial properties. Although the exact mechanism of isopropanol's disinfecting action is not known, it might kill cells by denaturing cell proteins and DNA, interfering with cellular metabolism, and dissolving cell lipo-protein membranes. Isopropanol is used in soaps and lotions as an antiseptic.

How it is made

Indirect hydration (process) is based on a two-step reaction of propylene and sulfuric acid, in the first step, mixed sulfate esters, primarily isopropyl hydrogen sulfate, but also diisopropyl sulfate, form, these are then hydrolyzed, forming (isopropanol) and sulfuric acid.

Acid-catalyzed direct hydration of propylene (has three basic processes of commercial operation which are): (1) vapor-phase hydration over a fixed-bed catalyst of supported phosphoric acid or silica-supported tungsten oxide with zinc oxide promoter, (2) mixed vapor-liquid-phase hydration at low temperature and high pressur

e using a strongly acid cation-exchange catalyst, and (3) liquid-phase hydration at high temperature and high pressure in the presence of a soluble tungsten catalyst.

/Other processes for production of isopropanol include:/ liquid phase oxidation of propane, incidentally by the reductive condensation of acetone, fermentation. Large-scale commercial biological production of isopropanol from carbohydrate raw materials has also been studied.
