ISO PROPYL ALCOHOL IPA

Isopropanol is also known as isopropyl alcohol. It is the simplest secondary alcohol and is one of the isomers of n-propanol. It is a kind of flammable liquid which is colorless with strong smell being similar to the smell of the mixture of ethanol and acetone. It is soluble in water, alcohol, ether, benzene, chloroform and most organic solvents and is miscible with water, alcohol, ether and can form azeotrope with water. Density (specific gravity): 0.7863g/cm3, melting point:-88.5 ℃, boiling point: 82.5 ℃, flash point: 11.7 ℃, ignition point: 460 ℃, refractive index: 1.3772. Its vapor can cause slight irritation on the eyes, nose and throat; it can be absorbed through the skin. Its vapor can form explosive mixture with air. Its explosion limit is 2.0% to 12% (by volume). It belongs to a moderate explosive hazardous material and flammable, low toxic substance. The toxicity of its vapors is twice as high as ethanol while oral administration causes the opposite toxicity.Isopropanol is a clear, colorless alcohol that is used in the production of acetone and as a solvent in the manufacture of various industrial and commercial products. It is used by the public for a number of different purposes and is commonly known as rubbing alcohol. It is flammable and miscible with both water and many different organic solvents. Isopropanol can be prepared via three different methods: indirect hydration of propylene (the ‘strong acid’ method), direct hydration of propylene, and catalytic hydrogenation of acetone.   

 Application:

• Isopropyl alcohol is an important chemical products and raw materials. It is mainly applied to various fields including pharmaceutical, cosmetics, plastics, fragrances, paint as well as being used as the dehydrating agent and cleaning agent in and electronics industry. It can also be used as the reagent for determination of barium, calcium, magnesium, nickel, potassium, sodium and strontium. It can also be used as the reference material of chromatographic analysis.
• In the manufacturing industry of circuit board, it is used as a cleaning agent, and the production of PCB holes for conductivity. Many people find that it can not only clean the motherboard with excellent performance, but also get the best results. In addition, it is used for other electronic devices, including cleaning disc cartridge, floppy disk drives, magnetic tape, and the laser tip of the disc driver of CD or DVD player.
• Isopropyl alcohol can also be used as the solvent of oil and gel as well as for the manufacture of fishmeal feed concentrate. Low-quality isopropanol can also be used in automotive fuels. As the raw material of production of acetone, the usage amount of isopropanol is reducing. There are several compounds which are synthesized from isopropanol, such as isopropyl ester, methyl isobutyl ketone, di-isopropylamine, di-isopropyl ether, isopropyl acetate, thymol and many kinds of esters. We can supply isopropanol of different quality depending on the end use it. The conventional quality of anhydrous isopropanol is more than 99%, while the special grade isopropanol content is higher than 99.8% (for flavors and drugs).
• Isopropyl Alcohol is used in a variety of applications including as a solvent for industrial processes and coating; as a component in cleaning, car care and deicing products; as a wetting agent for printing inks and as a feedstock in the manufacture of ester and Mogas/Luboil additives.
• isopropyl alcohol is a carrier, anti-bacterial, and solvent for skin care lotions. Isopropyl alcohol is made from propylene, a petroleum derivative.When compared to ethanol, 50% less is required for nucleic acid precipitation, thus minimizing the total volume to be centrifuged for DNA or RNA recovery.
• Isopropyl alcohol 70% is used as an ingredient in alcohol swabs and alcohol wipes for wound cleaning, it is found in hand sanitizers, and in ear drops to prevent swimmer's ear.
