A chemical compound having the molecular formula CH3CH (OH) CH3. Another name is propan-2-ol, medical alcohol. The liquid has a strong odor, flammable, colorless.
Isopropyl alcohol has a number of chemical properties. It is able to dissolve in alcohol, ether, chloroform, water. This substance does not interact with salts. Due to the ability to disappear well in a salt-free environment, isopropyl alcohol is easily isolated in water. It is enough to add sodium sulfate or ordinary table salt. This is its main difference from methanol and ethanol. The unofficial name for this method is salting. Spend it to separate isopropyl alcohol into layers.
Isopropyl alcohol is produced in three ways:
- Indirect hydration is the reaction of propylene with sulfuric acid. The result is a mixture of sulfate esters . They are also processed and get the right substance. A byproduct is diisopropyl alcohol.
- Direct hydration is carried out in the liquid or gas phase. Must be present acidic catalysts. The reaction of propylene and water. Both processes are the separation of isopropyl alcohol from H 2 O.
- Hydrogenation of acetone. Use crude acetone. It is hydrogenated with copper and chromium oxides or with Raney nickel.
Isopropyl
alcohol has been widely used. Most often it is used in pharmaceuticals. In industry, it is used as a solvent. In the chemical industry, it is used to produce cumene. According to the results of last year, isopropyl alcohol is often used in cosmetic products and in everyday life. This product is used as an additive in gasoline.
This alcohol is used in medicine as an effective disinfectant. They are treated with an injection site. It is also used as an antiseptic. Often used as a dehumidifier for otitis externa.
Absolute isopropyl alcohol differs from the usual degree of purification. It has the least amount of impurities. It dissolves resins and oils well, does not harm the paintwork. Because of this, he was widely used in the automotive industry. It is often added to a glass cleaner.
In laboratories, isopropyl alcohol is used as a preservative of biological origin. Use it for organics. It is a good alternative to synthetic preservatives, in particular formaldehyde.
Where to buy isopropyl alcohol? In wholesale warehouses. Most often they sell it in large quantities. Despite its widespread use, it can cause poisoning. Therefore, you need to take all precautions when using antifreeze, wipers, shaving lotions and so on.
The peculiarity of isopropyl alcohol is that it does not penetrate into oranism through the skin. But then it is perfectly absorbed through the lungs and stomach. It has a depressing effect on the central nervous system 2 times stronger than ethanol. In the liver, it is processed into acetone, and then excreted through the urinary system. The treatment is gastric lavage. If dehydration or shock occurs, conduct infusion therapy with sodium bicarbonate. Good hemodialysis.
