Applicant's summary and conclusion
- Conclusions:
- The boiling point / boiling range of UC-136 was determined using a melting point apparatus.
During the heating process. the liquefied test substance changed gradually from a clear practically colourless liquid into a clear brown liquid, starting at approximately 356 K (83°C). The solid which remained after cooling the liquid, still had the brown colour. This indicated decomposition and/or rearrandement.
The boiling point / boiling range of UC-136 and/or decomposition products was determined to be at approximately 423 K (150°C).
The measurements were performed at 101.83 kPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
