- Key result
- Atm. press.:
- 1 006 hPa
- Remarks on result:
- other: The substance was sublimated below the boiling point at 208ºC.
- Conclusions:
- The test substance was melted and sublimated before boling at 208.0ºC under atmospheric pressure of 1006 hPa.
- Executive summary:
A determination of the boiling point temperature was performed in accordance with EU method A.2 and OECD Guideline 103. GLP study. The boiling point of isoborneol was not observed because the test substance was melted and sublimated at 208.0 ± 0.1 ºC (average value) under atmospheric pressure of 1006 hPa.
Reference
The preliminary study and measurements were performed under atmospheric pressure of 1006 hPa. The preliminary study was carried out in order to determine the boiling temperature range of the substance. The study was performed in the temperature range 190-233 °C. The Isoborneol was melted and sublimated at 208.0°C.
Three series of measurements were performed in the temperature range 204–234°C. Below the temperature of 204ºC, the temperature gradient of 3 °C/min was used. Above 204ºC the used gradient was 1.0 °C/min. In all cases, the substance was melted and sublimated approximately 208ºC.
