Dibromofluoromethane（CAS# 1868-53-7)

dibromofluoromethane, chemical formula CBr2F2, is a colorless gas. It has the following properties:1. Gas under temperature and pressure. The boiling point of dibromofluoromethane is 4.6 degrees Celsius, and it is a colorless gas state at normal temperature.

2. Has a strong flame retardant. dibromofluoromethane is a gas that inhibits flame spread and can be used as a fire extinguishing agent.

3. High chemical stability. dibromofluoromethane is relatively stable at room temperature and does not easily react with other substances.

The main uses of dibromofluoromethane are:

1. As a fire extinguishing agent. Because of its flammability, it can be used to prevent and extinguish fire.

2. Used as refrigerant. dibromofluoromethane can absorb heat at low temperatures, so it is widely used in refrigeration and air conditioning systems.

3. Application in organic synthesis. dibromofluoromethane can be used as an intermediate in the synthesis of other compounds, for example in the preparation of pharmaceuticals and pesticides.

The preparation method of dibromofluoromethane mainly has the following kinds:

1. Brominated fluoromethane: first, fluoromethane reacts with bromine to generate brominated fluoromethane.

2. Brominated difluoromethane: then, brominated difluoromethane is further reacted with bromine to obtain brominated difluoromethane.

Note the following safety information when using dibromofluoromethane:

1. Avoid inhalation: dibromofluoromethane is a dangerous gas, and it may be harmful to health when inhaled at high concentrations. Should be used in a well-ventilated place, and wear a protective mask.

2. Prevent contact with skin and eyes: dibromofluoromethane may cause skin and eye irritation. Wear appropriate protective clothing and avoid contact with skin and eyes.

3. Avoid fire Source: Although dibromofluoromethane has high flame resistance, contact with open flame or high temperature material may still cause fire. Keep away from ignition and store properly.

4. Pay attention to sealing and storage: dibromofluoromethane should be stored in a sealed container, stored in a dry and cool place, away from fire and flammable materials.

Please note that the above is for reference only. When using or handling dibromofluoromethane, it should be operated according to the specific situation and relevant regulations.
