In water, 18.8 mg/L at 25 deg C
Soluble in benzene, chloroform
in water: none
Density of Carbon Tetrafluoride:
3.034 g/cu cm at 25 deg C
Manufacturing Methods of Carbon Tetrafluoride:
Tetrafluoromethane (carbon tetrafluoride, CF4) can be produced by reaction of CCl2F2 or CCl3F and hydrogen fluoride in the gas phase or by direct fluorination of carbon.
Hazards Identification of Carbon Tetrafluoride:
GHS Hazard Statements:
Aggregated GHS information from 3 notifications provided by 132 companies to the ECHA C&L Inventory.
H280 (100%): Contains gas under pressure; may explode if heated [Warning Gases under pressure – Compressed gas, Liquefied gas, Dissolved gas]
Information may vary between notifications depending on impurities, additives, and other factors. The percentage value in parenthesis indicates the notified
classification ratio from all companies. Only Hazard Codes with percentage values above 10% are shown.
Health Hazard of Carbon Tetrafluoride:
Excerpt from ERG Guide 126 [Gases – Compressed or Liquefied (Including Refrigerant Gases)]: Vapors may cause dizziness or asphyxiation without warning. Vapors
from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard of Carbon Tetrafluoride
Excerpt from ERG Guide 126 [Gases – Compressed or Liquefied (Including Refrigerant Gases)]: Some may burn but none ignite readily.
Containers may explode when heated. Ruptured cylinders may rocket.
Safety and Hazard Properties of Carbon Tetrafluoride:
Critical temperature: 299.00 K; critical pressure: 4.82 MPa
Critical temperature: 299.00 K; critical pressure: 4.82 MPa
Physical Dangers of Carbon Tetrafluoride
The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.
Chemical Dangers of Carbon Tetrafluoride
Decomposes on contact with hot surfaces or flames. Decomposes above 52°C . This produces hydrofluoric acid. Incompatible with certain metal powders (aluminium, zinc, beryllium).
Handling and Storage of Carbon Tetrafluoride:
Excerpt from ERG Guide 126 [Gases – Compressed or Liquefied (Including Refrigerant Gases)]: Do not touch or walk through spilled material. Stop leak if you can do it without risk.
Do not direct water at spill or source of leak. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. If possible,
turn leaking containers so that gas escapes rather than liquid. Prevent entry into waterways, sewers, basements or confined areas. Allow substance to evaporate. Ventilate the area.
Safe Storage of Carbon Tetrafluoride:
Cool. Keep in a well-ventilated room. Well closed. Separated from powdered metals.
Storage Conditions of Carbon Tetrafluoride:
Keep container tightly closed in a dry and well-ventilated place. Contents under pressure.
