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
