Difluorodiiodomethane - Introduction
Diiododifluoromethane, the chemical formula CF2I2, is a colorless liquid. The following is the introduction of the nature, use, preparation method and safety information of diiododifluoromethane:
Nature:
-Appearance: Colorless liquid with special smell.
-Density: 2.962g/cm³.
-Melting point:-52°C.
-Boiling point: 93-94°C.
-Solubility: insoluble in water, soluble in organic solvents such as alcohol, ether and ketone.
Use:
-Diiododifluoromethane is mainly used as a pharmaceutical and pesticide intermediate, especially as a disinfectant.
-It can be used to prepare iodine-containing or fluorine-containing compounds, and can also be used as a refrigerant.
Preparation Method:
-Diiododifluoromethane can be prepared by reacting fluoromethane with iodine in the presence of chloroalkyl. The reaction conditions are generally facilitated by high temperature and ultraviolet light.
Safety Information:
-Diiododifluoromethane is highly toxic and irritating to the eyes, skin and respiratory system.
-After exposure to the substance, rinse immediately with plenty of water and seek medical attention.
-When using, storing and handling diiododifluoromethane, take necessary safety precautions, such as wearing protective glasses, gloves and respirators.
-Under flammable conditions, the substance will produce toxic hydrogen fluoride gas, so it should be kept away from fire and high temperature.
Please note that diiododifluoromethane is a hazardous substance and should be handled and used in an appropriate laboratory or industrial environment. It is important to know the relevant safety information and follow the correct operating procedures.
