Isopropyl alcohol is a chemical substance with the formula CH3CH(OH)CH3. It is often called propanol-2, isopropanol, or IPS for short.

Isopropanol is a secondary alcohol of the aliphatic series. Capable of forming various ethers, it reacts with active metals, upon condensation with aromatic compounds derivatives are obtained, for example, isopropylbenzene. An excellent solvent, it dissolves itself in benzene and acetone, and is mixed with water and organic solvents in any proportions. Isopropanol dissolves natural and some synthetic resins, ethyl cellulose, polyvinyl butyral, most oils well. Not suitable for working with rubber and some plastics. With water, it forms an azeotropic mixture consisting of 87.9% propanol-2. It does not enter into chemical reactions with solutions of salts, which is used to isolate it from an aqueous solution. Isopropyl alcohol is a colorless liquid with a strong alcohol smell, more “gross” than the smell of ethyl alcohol. Freezing temperature: -89.5 ° C. Vapors of the substance mix easily with air and form an explosive mixture at a high concentration, so work with it in well-ventilated rooms and keep it away from open flames and heating devices.

Its main field of application is as a solvent in industry, perfumery, household chemicals, and repellents. The price of isopropyl alcohol is affordable, which, together with many useful properties, makes it a sought-after substance. It is used:

– In the automobile industry. The ability of IPS to freeze at very low temperatures is especially appreciated. The higher the concentration of isopropanol in the solution, the lower the freezing point of the liquid. It is used in antifreeze, windshield wipers, and added to gasoline.

– In medicine, isopropyl alcohol is used as a disinfectant (tampons and napkins are impregnated with a 60-70% solution, hands are cleaned).

– As an intermediate link in the preparation of other reagents in chemistry. Acetone and isopropylbenzene are obtained from isopropanol on an industrial scale.

— Used in gas chromatography.

— For preservation of organic materials (an alternative to formaldehyde), for preservation of analyzes in medicine and biology.

— Isopropyl alcohol as a cleaner is used in electrical engineering, electronics, metallurgy, furniture and optical fiber production, etc.

– In everyday life, it is used to remove stains, glue, oils, paint, dirt from fabrics, paper, wooden, metal and glass surfaces.
