Production method Carbon tetrafluoride is as below: difluoro-nitro-acetic acid could react to produce Carbon tetrafluoride, with the following condition: reagent: XeF2; solvent: CH2Cl2; reaction time: 5 - 10 ℃; yield: 38%.
As to its usage, it is widely applied in many ways. It could be used in making refrigerant, solvent, lubricating agent, electrical insulating material, coolant of; It could also used in producing low temperature liquid pressure gage or as the inert gases, or in lasing gas in all kinds of integrated semiconductor.
When deal with this chemical, you should be very cautious. Being a kind of highly flammable chemical, it may catch fire in contact with air, only needing brief contact with an ignition source, and has a very low flash point or evolve highly flammable gases in contact with water. And Carbon tetrafluoride may be narcotic at high concentrations and it may rupture violently and rocket under prolonged exposure to fire or heat the containers. Therefore, you should take the following instructions. In case of insufficient ventilation wear suitable respiratory equipment
In addition, you could obtain the molecular structure by converting the following datas:
(1)Canonical SMILES: C(F)(F)(F)F
(2)InChI: InChI=1S/CF4/c2-1(3,4)5
(3)InChIKey: TXEYQDLBPFQVAA-UHFFFAOYSA-N
