isopropanolin

Isopropanolin refers to the organic compound commonly known in English as isopropanol, isopropyl alcohol, or 2-propanol. It is a simple secondary alcohol with the formula C3H8O (often written as (CH3)2CHOH). Isopropanol is a colorless, volatile liquid that is miscible with water and many organic solvents. It is flammable and has a characteristic alcoholic odor. In industry and consumer products, it is widely used as a solvent, cleaning agent, and antiseptic.

Physical properties commonly cited for isopropanol include a boiling point around 82 °C and a density near 0.785 g/cm3 at room temperature. It readily mixes with water, alcohols, and most common organic solvents, making it versatile for dissolving oils, resins, and other substances. Its volatility allows it to evaporate quickly after application, leaving little residue.

Production and supply methods include industrial hydration of propene using acid catalysts such as sulfuric or phosphoric acid, which yields isopropanol directly. An alternative route is the hydrogenation of acetone, a method often linked to acetone production in related chemical processes. These routes provide the large-scale supply needed for manufacturing, research, and consumer products.

Applications span multiple sectors. Isopropanol serves as a general solvent in paints, inks, coatings, and cosmetics, as well as a cleaning and degreasing agent. It is also used as an antiseptic and disinfectant in healthcare and household products, and as an ingredient in pharmaceuticals and personal care formulations.

Safety and handling considerations are important. Isopropanol is flammable; vapors can form explosive mixtures with air. It can cause irritation to skin, eyes, and the respiratory tract, and excessive exposure may affect the central nervous system. Proper ventilation, storage away from heat sources, and avoidance of ignition sources are recommended.
