- Specific details on test material used for the study:
- Identity: Triazolone
Appearance: Off-white powder
Storage conditions: Room temperature (15 to 25°C), dark
Batch number: 0727/16
Purity: 99%
Expiry date: 28 April 2019
Date received: 28 April 2017 - Boiling pt.:
- < 270 °C
- Atm. press.:
- 1 021 mBar
- Decomposition:
- yes
- Decomp. temp.:
- 270 °C
- Remarks on result:
- not determinable
- Conclusions:
- The boiling temperature of Triazolone was not determinable as the test item decomposed at temperatures above approximately 270°C before boiling.
- Executive summary:
A study was performed to determine some physicochemical properties of the test item, Triazolone. The methods followed are amongst those described in Council Regulation (EC) No. 440/2008 and the OECD Guidelines for the Testing of Chemicals. The physicochemical properties which have been determined in this study are detailed below, together with the result obtained for each test.
The boiling temperature of Triazolone was not determinable as the test item decomposed at temperatures above approximately 270°C before boiling.
Reference
Barometric pressure: 1021 mbar
DSC showed a broad exotherm from approximately 270°C which indicated decomposition of the test item and a sharp endotherm at 330°C, possibly due to boiling of the decomposed sample. The earlier endotherm was consistent with the melting temperature.
A solid brown residue was present in the crucible at the end of the test.
Description of key information
The boiling temperature of Triazolone was not determinable as the test item decomposed at temperatures above approximately 270°C before boiling.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 270 °C
Additional information
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).
