Description of key information

3,3,3-trifluoro-2-(trifluoromethyl)propene is a monomer in imported polymers only. No free substance is manufactured or used in EU therefore no direct release to the environment is anticipated.

Additional information

3,3,3-trifluoro-2-(trifluoromethyl)propene is a gas at standard conditions with a water solubility of 272 mg/L. The high Henry Law’s constant of 8.05E+04 Pa m³/mol (25°C) indicates that 3,3,3-trifluoro-2-(trifluoromethyl)propene has a low affinity for distributing in the water compartment and in a system water/air it would have a high tendency to distribute quickly to the gas phase.

Basing on the experimental Log Kow = 2.42 and the calculated Log Koc = 2.28 a low affinity for organic matter is expected.

If released in the environment the main compartment of distribution would be therefore expected to be the atmosphere.

 

As other fluorochemical products 3,3,3-trifluoro-2-(trifluoromethyl)propene is not be expected to undergo significant biodegradation in any of the environmental compartments.

No data are available for abiotic degradation in any of the environmental compartments.
