are hydrogen peroxide and isopropyl alcohol the same？
1. Difference Between Hydrogen Peroxide and Isopropyl Alcohol
Are not the same. Hydrogen peroxide is an oxidant, and its disinfection principle is to kill microorganisms by oxidizing cell membranes and biomolecules in cells.
Isopropanol is an alcohol-based disinfectant, and its disinfection principle is to kill microorganisms by destroying their cell membranes and proteins.
2. Which is better hydrogen peroxide or isopropyl alcohol
It can kill all microorganisms such as bacteria, fungi, spores and viruses, among which peracetic acid has the strongest bactericidal ability, followed by hydrogen peroxide. Peroxide disinfectants are high-efficiency, quick-acting, and low-toxic disinfectants, which need to be prepared immediately after use. High concentrations can irritate and damage skin and mucous membranes.
3. Is rubbing alcohol and isopropyl alcohol the same?
Different physical and chemical properties:
Isopropanol, also known as 2-propanol, is an isomer of n-propanol. It is a colorless and transparent liquid with an odor like a mixture of ethanol and acetone. Commonly known as IPA, it is a volatile colorless transparent liquid with low toxicity, but the pure liquid cannot be drunk. Its boiling point is 78.4°C and its melting point is -114.3°C.
Alcohol is a saturated monohydric alcohol with a hydroxyl group, which can be regarded as a product in which a hydrogen atom in an ethane molecule is replaced by a hydroxyl group, or a product in which a hydrogen atom in a water molecule is replaced by an ethyl group. The ethanol molecule is a polar molecule composed of C, H, and O atoms, in which the C and O atoms are bonded by sp³ hybrid orbitals.
The main role is different:
Isopropanol is not only an important chemical product and raw material in life, it is mainly used in the manufacture of medicines, cosmetics, plastics, spices, paints, etc., and can also be used in industrial cleaning oils.
Alcohol is commonly used to make acetic acid, beverages, flavors, dyes, fuels, etc., and ethanol with a volume fraction of 70% to 75% is commonly used as a disinfectant in medicine.
Isopropanol, also known as tincture of iodine, is an organic compound that is soluble in water and most organic solvents such as alcohol, ether, benzene, and chloroform. Isopropanol is an important chemical product and raw material, mainly used in pharmaceuticals, cosmetics, plastics, spices, paints, etc.
Alcohol, also known as ethanol, is a volatile, colorless, transparent liquid at normal temperature and pressure, with low toxicity, and the pure liquid cannot be drunk directly. The aqueous solution of ethanol has the smell of wine, is slightly irritating, and tastes sweet. Ethanol is flammable and its vapors can form explosive mixtures with air. Ethanol is miscible with water in any ratio and miscible with chloroform, ether, methanol, acetone and most other organic solvents.
4. Isopropyl Alcohol vs. Hydrogen Peroxide: Benefits and Risks
It can react violently with oxidizing agents. Its vapor is heavier than air, and can spread from a lower place to a long distance, and it will cause backfire in case of fire. In case of high heat, the internal pressure of the container will increase, and there is a danger of rupture and explosion.
5. Summary: Applications of Hydrogen Peroxide
Hydrogen peroxide is usually formulated into aqueous hydrogen peroxide for use.
The use of hydrogen peroxide is divided into three types: medical, military and industrial. Daily disinfection is medical hydrogen peroxide. Medical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic cocci, and pathogenic yeasts. It is generally used for surface disinfection of objects. Hydrogen peroxide has an oxidizing effect, but the concentration of medical hydrogen peroxide is equal to or lower than 3%. When it is wiped on the wound surface, there will be a burning sensation, and the surface will be oxidized into white and bubbles. Just wash it with clean water. After 3-5 minutes Restores original skin tone.
In the chemical industry, it is used as a raw material for the production of sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide, etc., and an oxidant for tartaric acid, vitamins, etc. In the pharmaceutical industry, it is used as a fungicide, disinfectant, and oxidizing agent for the production of thiram insecticides and antibacterial agents. In the printing and dyeing industry, it is used as a bleaching agent for cotton fabrics, and for hair color after dyeing with vat dyes. It is used to remove iron and other heavy metals in the production of metal salts or other compounds. It is also used in electroplating solution to remove inorganic impurities and improve the quality of plated parts. It is also used for bleaching wool, raw silk, ivory, pulp, fat, etc. Hydrogen peroxide in high concentrations can be used as a rocket power booster.
Civilian use: To deal with the peculiar smell of the kitchen sewer, go to the pharmacy to buy hydrogen peroxide, add water and washing powder and pour it into the sewer to decontaminate, disinfect and sterilize; 3% hydrogen peroxide (medical grade) can be used for wound disinfection.
