1. As a chemical raw material, it can produce acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, isopropyl ether, isopropyl chloride, and isopropyl fatty acid esters and isopropyl chlorinated fatty acid esters. In fine chemicals, it can be used to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum isopropoxide, as well as pharmaceuticals and pesticides. It can also be used to produce diisopropyl ketone, isopropyl acetate, thymol, and gasoline additives. 2. As a solvent, it is a relatively inexpensive solvent in industry with a wide range of uses. It mixes freely with water and has a stronger dissolving power for lipophilic substances than ethanol. It can be used as a solvent for nitrocellulose, rubber, coatings, shellac, alkaloids, and other substances. It can be used in the production of coatings, inks, extractants, and aerosols. It can also be used as an antifreeze, detergent, gasoline blending additive, a dispersant in pigment production, a fixative in the printing and dyeing industry, an anti-fog agent for glass and transparent plastics, a diluent in adhesives, and an antifreeze and dehydrating agent. 3. Used as a chromatographic standard for the determination of barium, calcium, copper, magnesium, nickel, potassium, sodium, strontium, nitrite, and cobalt. 4. Used as a cleaning and degreasing agent in the electronics industry. 5. Used as an extractant for cottonseed oil in the oil and fat industry, it can also be used to degrease animal tissue membranes.
