Any other information on results incl. tables
For the correction Delta t of the boiling point to standard atmospheric pressure (1013.3 hPa) the equation, table and graphs of H.B. Hass and R.F. Newton in „CRC Handbook of Chemistry and Physics, 74th ed. 1993-1994", pages 15-16 and 15-17 were used.
Delta t = [(273.15+t) (3.0057-log p)] / [phi + 0.15(3.0057-log p)] (t in °C, p in hPa)
For the estimation of O the test item was classified in group 3 (amines) according to the table of H.B Hass and R.F. Newton.
| Onset / °C | Atmosperic Pressure / hPa | Phi (group 3) | Delta t /°C | Boiling point at 1013.3 hPa /°C |
| 64.61 | 1007 | 4.906 | 0.184 | 64.79 |
| 63.57 | 1007 | 4.904 | 0.183 | 63.75 |
The boiling point of the test item at atmospheric pressure (1013.3 hPa) was 64.3 °C.
Applicant's summary and conclusion
- Conclusions:
- The boiling point of the test item at atmospheric pressure (1013.3 hPa) was 64.3 °C.
