Introduction
Dibromodifluoromethane (CBr2F2), also known as halothane (halothane, trifluoromethyl bromide), is an organic compound. The following is an introduction to the properties, uses, preparation methods and safety information of dibromodifluoromethane:
Quality:
- Appearance: Colorless liquid
- Solubility: soluble in ethanol, ether and chloride, slightly soluble in water
- Toxicity: has an anesthetic effect and can lead to central nervous system depression
Use:
- Anesthetics: Dibromodifluoromethane, once widely used for intravenous and general anesthesia, has now been replaced by more advanced and safe anesthetics.
Method:
The preparation of dibromodimomethane can be carried out by the following steps:
Bromine is reacted with fluorine at high temperatures to give fluorobromide.
Fluorobromide is reacted with methane under ultraviolet radiation to produce dibromodifluoromethane.
Safety Information:
- Dibromodifluoromethane has anesthetic properties and should be used with caution, especially without professional guidance.
- Long-term exposure to dibromodifluoromethane may have adverse effects on the liver.
- May cause irritation if it gets into the eyes, skin, or respiratory system.
- When using dibromodifluoromethane, flame or high temperature situations should be avoided as it is flammable.
- When using dibromodifluoromethane, follow proper laboratory practices and personal protective measures.
