Molecular formula : (CH3) 2CHOH
nature : also known as 2-propanol. The transparent colorless flammable liquid, it smells like ethanol. -88.5 ° C melting point. Boiling Point 82.45 ° C 0.7855. 1.3776. Viscosity (20 ° C) 2.4mPa s. Flash point (open cup) 17.2 ° C With water, alcohol, ether, chloroform immiscibility. Explosion scope 2.02% to 7.99% (volume). The chemical nature of ethanol, propanol similar, but with SIN alcohol characteristics. Industrial production isopropanol are mainly two ways. (1) sulfate water legitimate, propylene and sulfuric acid as raw materials, obtained isopropyl hydrogen sulfate, and then hydrolyzed in isopropanol. (2) direct water legitimate, propylene and water to acid catalyst preparation. Isopropyl alcohol is an important chemical raw materials, is a common organic solvents. In addition, it can be used as anti-freeze, dehydrating agent and gasoline additives.
