Applicant's summary and conclusion
- Conclusions:
- Exothermal decomposition starts at 135 °C.
There is no melting and no boiling point up to the decomposition of the test substance. - Executive summary:
The boiling point of the substance was determined according EU method A.1/A.2 "Determination of the melting point", described in the EG-guideline 92/69. The DTA (Differential Thermal Analysis) and ISTA (Isothermal Step Thermal Analysis) showed that an exothermal decomposition started at 135 °C. There is no melting and no boiling point up to decomposition of the test substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
