Freon-11 - Introduction
Freon-11, chemical formula CFCl3, is a fluorocarbon, also known as Freon-11. The following is a description of the nature, use, formulation and safety information of Freon-11:
Nature:
1. Appearance: Freon-11 is colorless and odorless gas;
2. melting point:-104 ℃;
3. Boiling point: 23.8 ℃;
4. density: 1.489g/cm³;
5. Insoluble in water, limited solubility with organic solvents such as ethanol and ether;
6. has a more stable chemical properties, not easy to burn.
Use:
1. As a refrigerant and refrigerant, it is commonly used in air conditioners, refrigeration equipment, refrigerators, etc;
2. It can also be used as a component of solvent and foam fire extinguishing agent;
3. In industrial use, Freon-11 can be used for cleaning electronic devices, decontamination, etc.
Preparation Method:
The preparation of Freon-11 is usually obtained by reacting chloroform or dichloro-fluoromethane with hydrofluoric acid. The reaction formula is as follows:
CHCl3 HF → CFCl3 HCl
Safety Information:
1. Freon-11 has a certain degree of toxicity and destruction of the atmospheric ozone layer, so it is included in the list of internationally agreed "dangerous gases;
2. Long-term exposure to high concentrations of Freon-11 may cause damage to the respiratory system, central nervous system and liver;
3. When using or disposing of Freon-11, you must comply with relevant safety regulations and avoid its leakage into the environment;
4. when necessary, should use appropriate protective measures, such as breathing apparatus and protective gloves.
In general, Freon-11 plays an important role in applications such as refrigeration, cleaning and foam fire suppression, but it is also necessary to pay attention to its potential harm to human health and the environment. During use and handling, care should be taken to comply with relevant safety guidelines and regulations.
