What is isopropyl alcohol
A chemical compound having the molecular formula CH3CH (OH) CH3. Another name is propan-2-ol, medical alcohol. The liquid has a strong odor, is 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 property of well disappear in salt-free medium, isopropyl alcohol is easily isolated in water. It is enough to add sodium sulphate or common table salt. This is its main difference from methanol and ethanol. The unofficial name of this method is "salting". Conduct it to separate isopropyl alcohol into layers.
Isopropyl alcohol is produced in three ways:
- Indirect hydration is the reaction of propylene with sulfuric acid. As a result, a mixture of sulfate esters is obtained. They are also processed and the right substance is obtained. A by-product is diisopropyl alcohol.
- Direct hydration is carried out in the liquid or gas phase. Acidic catalysts must be present. Reaction of propylene and water is carried out. Both processes consist in 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 the use of Raney nickel.
This alcohol is used in medicine as an effective disinfectant. They process the injection site. Also it is used as an antiseptic. It is often used as a dehumidifier for external otitis media.
Isopropyl alcohol absolute is different from the usual degree of purification. It has the smallest amount of impurities. It dissolves the resin and oil well, does not harm the paintwork. Because of this, it is widely used in the automotive industry. It is often added to the liquid for washing glasses.
In laboratories, isopropyl alcohol is used as a preservative of biological origin. Use it for organic. This is a good alternative to synthetic preservatives, in particular formaldehyde.
Where to buy isopropyl alcohol? At wholesale warehouses. Sell it more often in large quantities. Despite its wide application, it can cause poisoning. Therefore, you need to take all precautions when using antifreezes, windshield wipers, shaving lotions and so on.
The peculiarity of isopropyl alcohol is that it does not penetrate the oranism through the skin. But it is perfectly absorbed through the lungs and stomach. It exerts a depressant effect on the central nervous system 2 times stronger than ethanol. In the liver, it is processed into acetone, and then it is excreted through the urinary system. Treatment consists in washing the stomach. If there is dehydration or shock, an infusion therapy is performed using sodium bicarbonate. Well shows itself hemodialysis.
