Hydrogen Peroxide vs Isopropyl Alcohol
On the difference between hydrogen peroxide and isopropanol
Hydrogen peroxide and isopropanol have significant differences in physical properties, chemical properties and uses.
First talk about physical properties. Hydrogen peroxide is a colorless and transparent liquid under normal conditions, with a slightly acidic taste and can be miscible with water in any ratio. Its density is slightly higher than that of water, and its boiling point is quite high, about 150.2 ° C. Isopropanol is also a colorless and transparent liquid, but it has a special mellow taste. Its density is less than that of water, its boiling point is relatively low, about 82.45 ° C, and its volatility is stronger than that of hydrogen peroxide.
Subdescriptive properties. Hydrogen peroxide has strong oxidation, which is its key characteristic. When exposed to reducing agents, it is easy to release new oxygen and undergo oxidation reactions. For example, ferrous ions can be oxidized to iron ions. And under light or heat conditions, it is easy to decompose by itself to produce water and oxygen. And isopropanol is an alcohol with typical chemical properties of alcohol. It can react with active metals such as sodium to replace hydrogen; it can also occur esterification reaction, and carboxylic acid is catalyzed by concentrated sulfuric acid to form ester compounds. At the same time, isopropanol can be oxidized, and can be oxidized to acetone under copper or silver catalysis and heating conditions.
As for uses. Hydrogen peroxide has a wide range of uses. Because of its strong oxidizing properties, it is often used as a disinfectant, which can kill a variety of bacteria and viruses, and the decomposition products are water and oxygen, which are non-polluting. It is commonly used in medical, food processing and other fields. It is also used as a bleaching agent for fabrics, paper and other In chemical production, it is an important oxidant. Isopropanol is mainly used as a solvent, because it has good solubility to most organic compounds, and is widely used in coatings, inks, cosmetics and other industries. Because of its volatility and bactericidal properties, it is also used as a disinfectant, but the disinfection principle is different from hydrogen peroxide. It is mainly sterilized by denaturing proteins, and is often used for skin disinfection.
In summary, although hydrogen peroxide and isopropanol are both common chemicals, they are quite different in terms of physical properties, chemical properties and uses. When applying, they should be carefully screened and selected reasonably.
