The vapour pressure curve as a function of temperature was determined with KARMALONE according to the OECD method No. 104 (dynamic method) and used to extrapolate the normal boiling temperature.
Normal boiling temperature of KARMALONE : 531 K (258 °C)
The 95 % confidence limits are : 518 K - 544 K (245 °C - 271 °C).

Temperature 1: measured when increasing the pressure
Temperature 2 : measured when decreasing the pressure.
Means of temperatures 1 and 2 were calculated, results were reported on a log P versus 1/(T-43) diagram (Antoine’s equation: log P = A + B/(C + T) with C = - 43 according to Cox, where T is in Kelvin), see Appendix 2. The linear regression parameters were calculated (least squares method):
log P = A + B * 1000/(T - 43)
A = 8.12571, B = - 2.49749 (R2= 0.99523, coefficient of determination).
This relationship was used to calculate by extrapolation the normal boiling point, i.e. the boiling temperature corresponding to 1013 hPa.
The result is : 531 K (258 °C).
The 95 % confidence limits are : 518 K - 544 K (245 °C - 271 °C).
