Acetone is a colorless and transparent liquid with the chemical formula C3H6O. It is a highly volatile solvent, which is usually used to clean the surface of metal, plastic, glue and other materials, or as a foaming agent, fuel supplement and so on. Since the vapor of acetone can cause headaches, dizziness and other uncomfortable symptoms, special attention should be paid to safety during use.

properties:

acetone is a transparent colorless liquid at room temperature and pressure, with strong solubility. It is miscible with water and volatile in the air, so it is necessary to maintain a well-ventilated environment during use. The relative density of acetone is 0.79, the boiling point is 56.2 degrees Celsius, and the ignition point is 466 degrees Celsius. Its flash point is relatively low, -18 degrees Celsius, flammable.

uses:

acetone is a widely used organic chemical, which is widely used in various fields. In industrial production, acetone can be used as a raw material for the production of plastics, fibers, rubber and other materials, or as a cleaning agent for engineering plastics, pigments, resins and so on. It is also used in the production of fuel, cosmetics, etc.

In the pharmaceutical industry, acetone is also one of the very common pharmaceutical ingredients. It can be used in the preparation of various drugs, such as anesthetic drugs, disinfectants, disinfectants, etc. In scientific experiments, acetone is also a very useful experimental solution, which can be used to prepare various compounds as well as to purify compounds.

precautions: It is very important to
the correct use of acetone
because it is a flammable and highly volatile compound. During use, you need to pay attention to the following points:

1. Acetone cannot be mixed with strong oxidants, concentrated nitric acid and other strong chemicals to avoid explosion and other hazards.

2. During the use of acetone, it is necessary to pay attention to ventilation to ensure that the use environment will not produce a large amount of toxic gases that cause harm to the human body.

3. Acetone should be kept in a closed container, away from light, heat and fire. Do not place it with other chemicals during storage.

4. When using acetone for cleaning and other operations, you need to wear chemical-resistant gloves and protective glasses to protect your own safety.

In short, understanding the nature of acetone and precautions for use, and mastering the correct method of use, can make us use it more safely and avoid accidental risks.
