DBDPEthane's characteristic volume was calculated using the atomic and bond contributions given in the REACH Guidance, Chapter R.7A. Its relative density was calculated by dividing the molecular weight by its characteristic volume.
Applicant's summary and conclusion
- Conclusions:
- DBDPEthane's calculated relative density (2.67 gm/cm3) indicates it will sink in water.
- Executive summary:
DBDPEthane's characteristic volume was calculated to be 363.66 cm3/mol. The characteristic volume is closely correlated with molar volume. The REACH Guidance (Chapter R.7A) states that relative density can be predicted by the molecular weight divided by the molar volume. DBDPEthane's relative density is calculated to be 2.67 gm/cm3) by this method. DBDPEthane's water solubility is low (<the 50 g/L given in the REACH Guidance), and its calculated density indicates it will sink in water.
