Applicant's summary and conclusion
- Conclusions:
- The substance decomposed from approximately 344 +- 0.5 K. No value for the melting temperature is available.
- Executive summary:
The Phosphonitrile chloride catalyst, commonly named as Sparc catalyst, is mainly composed
of the dimer [PCl3=N-PCl2=N-PCl3]+PCl6
- and the trimer
[PCl3=N-PCl2=N-PCl2=N-PCl3]+PCl6
The solid catalyst was named DCNS 170 (Dow Corning New Substance) and was tested by SafePharm Laboratories Ltd to determine the melting temperature. The test material decomposed from approximately 344 ± 0.5K, by differential scanning
calorimetry, using ASTM E537-86 and Method A1 of Commission Directive 92/69/EEC.
As DCNS 170 decomposed, no value for the melting temperature is available.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
