Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Input Parameters:
Molecular Mass (g/mol): 112.99
Temperature (°C): 20
Log Kow: 2.0
Vapor Pressure (Pa): 6620 (49.7 mmHg)
Henry's Law Constant: 0.00282 atm-m3/mole (Henry database) - Environmental properties:
- Half-lives (hr) Based upon AOPWin and Biowin (ultimate)
Air: 581
Water : 900
Soil: 1800
Sediment: 8100

According to U.S. EPA TRI Database, >99.9% of reported PDC emissions are to the atmosphere
Results and discussion
Percent distribution in media
- Air (%):
- 98.8
- Water (%):
- 0.98
- Soil (%):
- 0.2
- Sediment (%):
- 0
- Other distribution results:
- Advection in air accounts for 89.2% of removal rate and reaction in air accounts for 10.6% of removal rate.
Advection and reaction in water, sediment, and soil account for 0.2% of removal rate
Any other information on results incl. tables
Applicant's summary and conclusion
- Conclusions:
- Level I and III models predict that PDC will be predominately transported to the atmosphere, with little or no potential for deposition to soil and water. Advection is the predominant removal mechanism in the atmosphere.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
