Applicant's summary and conclusion
- Conclusions:
- A sharp endotherm with an onset a mean temperature of 53.26°C, and a peak at a mean tempera ture of 56.37°C was concluded to be the test substance melting. A second broad endotherm with an onset at a mean temperature of 335.78C and a peak at a mean temperature of 350.28C was consd iered to be due to the test substance boiling with possible decomposition. The mean melting point and mean boiling point of Beta Ketosulfide were evaluated at 56.37C (from 7 results) and 350.28C (from 4 results) respectively.
- Executive summary:
The experimental procedures followed those described in EC Directive 92/69/EEC Method Al and OECD Guidelines 102 for the melting temperature determination. The melting point for this substance was determined to be 56.37C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
