(Isopropyl Alcohol)


Isopropyl alcohol (IPA) is miscible with water, alcohol, ether, and chloroform. It dissolves ethyl cellulose, polyvinyl butyral, various oils, alkaloids, gums and natural resins. Unlike ethanol or methanol, it is insoluble in salt-containing solutions. Isopropanol can be separated by adding a salt such as sodium chloride, sodium sulfate, or any other inorganic salt to the aqueous solution. This is because IPA is less soluble in common salt solution, and through a process commonly known as salt analysis, IPA can be concentrated and separated into different layers.



Protective coatings, inks, cleaning compounds, anti-freeze and de-icing agents, lacquer thinner formulations, and nitrocellulose.

Also used in the manufacture of acetone and derivatives, the manufacture of glycerol and isopropyl acetate, and solvents for aromatic and other oils, alkaloids, glue, and resins. Possible solvents for cellulose derivatives, coating solvents, anti-freeze agent for liquid fuel, enamel, extract processing, dehydrating agent, preservatives, lotions, and denaturants.
