Results and discussion
Boiling point
- Boiling pt.:
- 301 °C
- Atm. press.:
- 101.3 kPa
Any other information on results incl. tables
The determination of the Boiling Point was performed by visual judgement using the capillary method.
At about 315 °C in the preliminary test, the number of air bubbles increases and a stream of air bubbles were visible. The colour changed from white to light yellow to light brown using a heating rate of 10 °C/min.
To confirm the result obtained in the preliminary test, the determination of the boiling point was performed in triplicate, heating quickly up to 290 °C and afterwards slowly using a heating rate of 1 °C/min.
A clear boiling point, as defined in the guideline with a current stream of bubbles evolving from the capillary, was observed at a heating temperature of 301 °C (575 K). The results were evaluated because they fulfill the criteria of repeatability.

Applicant's summary and conclusion
- Conclusions:
- In conclusion, of N-[3-tris(trimethylsilyloxy)-silylpropyl]prop-2-enamide starts boiling at 301 °C (575 K) at ambient barometric pressure (101.3 kPa).
- Executive summary:
- Title:Determination of the Boiling Point ofN-[3-tris(trimethylsilyloxy)-silylpropyl]prop-2-enamide
- Purpose:The purpose of this study was to evaluate the boiling point of N-[3-tris(trimethylsilyloxy)-silylpropyl]prop-2-enamide by the capillary method according Siwoloboff using an electronic controlled heating system.
- Results:The determination of the Boiling Point was performed by visual judgement using the capillary method. At about 315 °C in the preliminary test, the number of air bubbles increases and a stream of air bubbles were visible. The colour changed from white to light yellow to light brown using a heating rate of 10 °C/min. To confirm the result obtained in the preliminary test, the determination of the boiling point was performed in triplicate, heating quickly up to 290 °C and afterwards slowly using a heating rate of 1 °C/min. A clear boiling point, as defined in the guideline with a current stream of bubbles evolving from the capillary, was observed at a heating temperature of 301 °C (575 K). The results were evaluated because they fulfill the criteria of repeatability.
Conclusion:In conclusion, ofN-[3-tris(trimethylsilyloxy)-silylpropyl]prop-2-enamidestarts boiling at 301 °C (575 K) at ambient barometric pressure (101.3 kPa).
