Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- 25 - 150 °C
- Atm. press.:
- 1 atm
- Decomposition:
- no
- Remarks on result:
- other: At the start of the test at 25 °C the test substance was a highly viscous non-stirrable mass. The viscosity of the test substance decreased throughout the whole test beginning at 25 °C. At about 150 °C the test substance was a liquid of low viscosity.
Applicant's summary and conclusion
- Conclusions:
- The experimental determined melting range of the test substance is < 25 °C to 150 °C.
- Executive summary:
The melting temperature was determined experimentally using the capillary method of OECD and EC.
At the start of the test at 25 °C the test substance was a highly viscous non-stirrable mass.
The viscosity of the test substance decreased throughout the whole test beginning at 25 °C. At about 150 °C the test substance was a liquid of low viscosity. Due to these observations no melting point but a melting range was stated.
Range: <25 °C to 150 °C
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
