Những điều về Acetone có thể bạn chưa biết?

Acetone is a component of a variety of consumer products, from medicinal herbs, cosmetics to unprocessed and processed foods, and is a very familiar chemical to women. So what do you know about this substance? The article below may help you understand more things What is Acetone?? What are the properties and applications of acetone solvent?

Chemical formula of Acetone

I. What is Acetone?

1. Definition and properties of acetone

• Acetone or acetone also known as Dimethyl Formadehyde, is an organic compound, with the formula (CH3)2CO. Acetone is a colorless, flammable liquid that evaporates quickly and has a characteristic odor.
• Acetone is soluble in water and is a solvent mainly used for cleaning in the laboratory, as well as a raw material used to synthesize organic substances.
• Acetone is synthesized in the laboratory but also exists in nature such as in air, drinking water, and soil.
• In the human body acetone is produced and excreted through metabolism and is normally present in the blood and urine. It is produced by organs and food metabolism and is excreted in the urine. If acetone is not eliminated for some reason, it can cause shock because at this time, the acid in the blood increases.

2. Acetone production methods

Old method

Previously, acetone was produced by distilling acetate, such as calcium acetate, in a decarboxylation reaction.

Ca(CH3COO)2 → CaO + CO2↑ + (CH3)2CO

Modern method

• Nowadays Acetone is produced directly or indirectly from propene. Produced directly by oxidation or hydrogenation of propene, producing 2-propanol (isopropanol) and when isopropanol is oxidized, acetone is produced.
• Sometimes the solvent acetone is produced as a byproduct of the distillation industry.

II. For what purposes is Acetone used?

1. In industry

a. Use as a solvent

• Acetone is one of the common industrial solvents, widely used in the production of plastics, resins, plastics, paint production, etc. It is also used as a solvent in pharmaceutical production, as an excipient. in some medications. In particular, it is also a solvent for synthetic rubber, acrylic, nitrocellulose and many other industries.
• Acetone is a good solvent for plastics and some synthetic fibers. Acetone is used to dilute polyester resins, used in detergents and cleaning tools.
• Used to mix 2-component epoxy glue before curing and is used as one of the volatile ingredients of some paints and varnishes.
• As a heavy-duty degreaser, acetone is useful for cleaning metal before painting and also for removing rosin after welding has been completed.
• Used as a solvent in the pharmaceutical industry and as an excipient in some drugs, and for the production of denatured alcohol.
• Although flammable, acetone is widely used as a solvent for transporting and storing acetylene, as it is unsafe when subjected to high pressure as a pure compound. The containers always contain acetylene dissolved in acetone. One liter of acetone can dissolve about 250 liters of acetylene.

b. Chemical intermediates

• Acetone is used to synthesize methyl methacrylate.
• Synthesis of bisphenol A.

3. In medicine and beauty techniques

• Acetone solvent is a very common chemical in many industries and nail salons. It is widely used in medicine and beauty techniques in general. At the same time, it is also classified as a food additive and food packaging and preservation.
• Acetone is also often used for chemical peeling.
• Is the main ingredient in nail polish removers, super glue removers and detergents for ceramics and glass.
• In addition, Acetone solvent is also used in art printing.

III. Is Acetone harmful?

Although acetone has many uses, its harmful effects are also many:

• Acetone in soil and water is harmless because it changes very quickly because microorganisms convert it into other compounds, but when combined with other substances such as hydrogen peroxide or chloroform, acetone becomes harmful.
• Acetone will be converted by the liver into harmless products and can become energy for the body when only a small amount of acetone is present. However, if a large amount of acetone enters the body, it will cause unhealthy effects such as vomiting, or in more severe cases, vomiting blood.
• In the eyes, when splashed with this solution, it will cause eye irritation and damage to the cornea, but it will usually heal after a few days. If exposed for a long time, the cornea can become temporarily or permanently cloudy. Drinking or inhaling acetone vapor can lead to irritation and swelling of the throat mucosa. Long-term smell of acetone will cause damage to the nasal mucosa, weaken the respiratory system and make it difficult to breathe. If you have acetone poisoning, your heart rate will beat very fast and your blood pressure will drop significantly.
• Acetone poisoning causes the central nervous system to decrease in activity, the patient feels sleepy, moves uncoordinated, the body moves continuously and can become coma. It can cause difficulty breathing, slow breathing, weak breathing, and bronchial itching.
• The dangerous characteristic of Acetone is that it ignites quickly, causing fire and explosion, so when used and stored, it must be kept away from heat sources and avoid direct sunlight. Along with its volatile nature, it must be stored during use. sealed, not letting air in.

IV. Safety measures when using Acetone

This chemical has been extensively studied and is generally recognized to have low acute and chronic toxicity if ingested or inhaled. Therefore, when exposed to this chemical, to protect our health we need to take preventive measures:

• Try to limit contact and inhalation of this chemical. If your job requires frequent contact, you need to wear protective gear: wear long sleeves, wear a medical mask, wear goggles, etc.
• The product should be kept in a dry, cool place, out of reach of children.

VII. Some frequently asked questions about Acetone

Is acetone toxic?

Acetone is a colorless liquid with a pungent odor and is commonly used in many fields such as industry, medicine and home. For the average user and when used properly, acetone is not harmful to health and is considered safe.

However, acetone can cause explosion when exposed to fire, so it is necessary to pay attention to the risk of fire and explosion and ensure safety when storing and using. When in contact with skin and eyes, acetone can cause irritation, so direct contact should be avoided and protective measures such as gloves and goggles should be used when handling.

How to destroy gel polish with Acetone?

Do this in a well-ventilated area and away from fire. You pour a little acetone onto a gauze pad or cotton pad. Then place gauze on the nail and keep it for about 5-7 minutes, the gel nail polish will be removed quickly. Don’t forget to moisturize your hands after removing your nails.

Is Aromatic Gasoline Acetone?

Aromatic gasoline is not Acetone. Aromatic gasoline is a liquid used as fuel for internal combustion engines. It is typically a mixture of hydrocarbons with 4 to 12 carbon atoms, such as benzene, toluene, ethylbenzene, and xylene (abbreviated BTEX). Aromatic gasoline has a characteristic scent and is widely used in cars, motorbikes and other internal combustion devices.

Meanwhile, acetone is another chemical compound. This is a clear liquid with a characteristic pungent odor and is commonly used in industry, nail cleaning and dyeing, surface cleaning, and in some household products.

Is acetone alcohol?

Acetone is not alcohol. Alcohols are a group of chemical compounds containing a hydroxyl group (-OH). Alcohol can be divided into several types, including ethanol (ethyl alcohol) used in beverages such as alcohol and isopropyl alcohol (isopropyl alcohol) commonly used as a detergent and cleaning agent.

What is the boiling point of Acetone?

The boiling point of Acetone (acetone) is about 56.5 degrees Celsius (133.7 degrees Fahrenheit) at standard air pressure (1 atm). However, the specific boiling temperature may fluctuate slightly depending on the environmental pressure. Acetone has a low boiling point compared to many other solvents, making it popular in chemical and industrial processes where a rapidly evaporating solvent is needed.

Is acetone coated with silver?

Acetone is not capable of silvering. Silvering is the process of applying a thin layer of silver to the surface of another material such as metal, glass or plastic. To silver a surface, it is often necessary to use specialized chemicals, such as silver nitrate solutions and other silver compounds. Acetone is a strong solvent that does not react with silver and is incapable of silvering.
