- Endpoint:
- thermal stability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: DTA Screening method
- Deviations:
- not specified
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Test substance thermally stable:
- yes
- Operating temp.:
- 350 °C
- Sublimation:
- no
- Transformation products:
- not specified
- Test substance stable to sunlight:
- not determined

- Conclusions:
- Taking into account the short residence times of the substance to be evaporated from a thermal point of view, there are no objections to the conversion of the substance into the gas phase phosgenation apparatus. Residence times of more than one hour at temperatures above 300 ° C should be avoided.
- Executive summary:
According to the DTA-Screening test the test substance was transferred via two micro-exchangers made of V4A at 0.6 bar and 160 ° C to 270 ° C in a gas-phase phosgenation apparatus. The first heat exchanger was used for evaporation, the second for overheating to 20 ° C to 30 ° C above the boiling point to prevent droplets safely. The maximum heating medium temperature was 350 ° C, the heating medium Marlotherm SH is separated from the product by a double barrier, so that mixing can be excluded. The screening DTA (heating rate 3 K/min., closed glass ampule) showed the endothermic evaporation of the sample. With the addition of V4A showed from 140 ° C, a weakly exothermic oxidation reaction. Safety related exothermic reactions were not observed. Taking into account the short residence times of the substance to be evaporated from a thermal point of view, there are no objections to the conversion of the test substance into the gas phase phosgenation apparatus. Residence times of more than one hour at temperatures above 300 ° C should be avoided.

Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
