Uses of Dichlorodifluoromethane: it can be used as refrigerant, fire extinguishing agent, pesticide and spray. It is used to produce trifluormethyl-dibrom-methylenimin by reaction with bis-trifluoromethyl-amine. The reaction occurs with reagent BBr₃ at 100 °C for 16 hours. The yield is about 93%.

Dichlorodifluoromethane is used to produce trifluormethyl-dibrom-methylenimin by reaction with bis-trifluoromethyl-amine.

When you are using this chemical, please be cautious about it. As a chemical, it is highly flammable and dangerous for the ozone layer. What's more, it is danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. During using it, wear suitable protective clothing and gloves. Avoid contact with skin and eyes and do not breathe gas/fumes/vapour/spray. Keep container tightly closed and away from sources of ignition. This material and its container must be disposed of as hazardous waste. In case of accident or if you feel unwell seek medical advice immediately.
