isopropyl alcohol (IPA,67 63 0) Uses
Solvent Applications:
- IPA is widely used as a solvent due to its miscibility with water, fatty compounds, and many organic substances.
- It freely mixes with water and exhibits stronger solvency for lipophilic substances than ethanol, making it suitable for nitrocellulose, rubber, paints, shellac, alkaloids, and other materials.
- Isopropanol is also used in manufacturing paints, inks, extraction agents, aerosol propellants, and more.
Medicine and Disinfection:
- Isopropanol possesses excellent bactericidal properties. Its 70% aqueous solution is widely used as a disinfectant in homes and hospitals.
- It is commonly employed for skin disinfection, hand sanitization, and sterilizing medical instruments.
- IPA also serves as a preservative for biological samples and functions as a reaction medium in certain chemical processes.
Chemical Raw Material:
- IPA is a vital chemical intermediate for producing acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, isopropyl ether, isopropyl chloride, isopropyl esters of fatty acids, and chlorinated fatty acid isopropyl esters.
- In fine chemicals, it is employed to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum isopropoxide, pharmaceuticals, and pesticides.
Other Applications:
- Isopropyl alcohol (IPA/Isopropanol) serves as an antifreeze agent, cleaning agent, gasoline blending additive, pigment production dispersant, dyeing industry fixative, and anti-fogging agent for glass and transparent plastics.
- It also functions as a defoaming agent in water-based fracturing fluids for oil wells and a degreasing agent for animal-derived tissue membranes.
