- Remarks on result:
- other: Range: 84.8 ± 0.5°C (358.0K) to 90.1 ± 0.2°C (363.3K). Upon melting the test substance was clear and colorless.
- Conclusions:
- The melting point for the test substance was 84.8°C (range of 84.8 to 90.1°C) at 756.9 mm Hg.
- Executive summary:
The melting point of the test substance was measured in accordance with OECD Guideline 102 and EPA OPPTS 830.7200. Subsamples of the test substance were heated in melting point capillary tubes in a temperature-controlled heating block. Measurement of melting point was limited to ≤ 400°C (approximately 673K), the maximum specified for the instrumentation used. The temperature at which fine droplets adhered uniformly to the wall of the melting point tube was accepted as the melting point. If a range of temperatures was noted between the formation of the fine droplets (beginning of melting) and transition to a liquid (end of melting), a melting range was reported. The definitive melting point test provided a mean melting point of 84.8±0.5°C (358.0K) and a mean melting range from 84.8±0.5°C (358.0K) to 90.1±0.2°C (363.3K) for the three tests. Upon melting the test substance was clear and colorless.
