Description and Uses
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.
Isopropyl alcohol is used in the production of acetone, isopropyl halides, glycerin, and aluminum isopropoxide; employed widely as an industrial solvent for paints, polishes, and insecticides; as an antiseptic (rubbing alcohol); and in organic synthesis for introducing the isopropyl or isopropoxy group into the molecule. Being a common laboratory solvent like methanol, the exposure risks are always high; however, its toxicity is comparatively low.
