- Key result
- Melting / freezing pt.:
- 129.3 °C
- Atm. press.:
- 101.3 kPa
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: corresponding to 402.4 K
- Conclusions:
- The melting point of D-8 was determined to be 402.4 K (129.3 °C) using a photocell detection method in accordance with the OECD Guideline 102.
- Executive summary:
The melting point of D-8 was determined according to OECD guideline 102: Melting point/Melting range (1981). The melting point of D-8 was 402.4 K (129.3 °C), as determined using the photocell detection method.
Reference
The mean of triplicate measurement of the melting point was 402.4 K (129.3 °C), which was in the temperature range described in the quality criteria section of the guideline. The accuracy was larger than the criteria (± 0.1 K), and accordingly the S.D. was calculated as 0.2 K.
