Boiling pt.:

>= 330 - <= 337 °C

Atm. press.:

102.4 kPa

Any other information on results incl. tables

Results
The sample shows an endothermic boiling peak in the 320 to 360 °C region.

Table 1 – boiling point test

Measurement	Onset [°C]	Peak [°C]	Atmospheric pressure [hPa]
1	328.8	336.7	102.4
2	331.1	337.1	102.4

 

Based on lower onset and higher peak values, the boiling range is 330 – 337 °C.
