Dichloromethane, also known as chloroform, is a chemical substance whose molecular formula is CH2Cl2. It is a colorless, clear liquid that is volatile at room temperature and pressure. Dichloromethane is an important organic synthetic solvent and has many applications.

1. industrial use

1. Dichloromethane can be used as an important component of organic solvents such as paints, coatings, glue, etc., because it can be dissolved by a variety of substances, with a faint sweet taste, safe and convenient to use.

2. Dichloromethane can also be used as a coating agent and a weak corrosive agent, and is widely used in electrical cleaning, manufacturing and food industries.

3. Dichloromethane can also be used in the production of dyes and cosmetics, non-toxic and harmless, and safe for the human body.

2. for medical use

1. Dichloromethane has good anesthesia and can be used for anesthesia of various surgical operations, such as anesthesia target spot, ordinary target spot, pleural cavity device, cardiopulmonary resuscitation, etc.

2. Dichloromethane can also be used to treat viral infections and prevent pet diseases.

3. environmental protection problem

1. Dichloromethane in the body of the decomposition rate is very slow, long-term accumulation will cause the organism endotoxin concentration and damage, the environment and biological cause great impact, need to strengthen environmental awareness and reduce the amount of use.

2. Due to the strong volatility of dichloromethane, it is easy to cause harm to the human body. During use, attention should be paid to protective measures to avoid contact.

Dichloromethane as an organic compound is widely used in industry, medicine and many aspects of life. With the increasingly serious environmental problems, we need to pay more attention to the environmental problems of dichloromethane, make its use more scientific and reasonable, and promote sustainable development.
