The first drop of condensed product was seen at 141.2°C. In the repeat measurement the temperatures were 141.3°C (gas room) and 141 (liquid). The mean value of the gas room temperatures was 141.3°C. The corrected temperature according to Sydney-Young (with correction factor 0.035°C/hPa) is 141.2°C.

Conclusions:
2,2,4-Trimethyl-1-oxa-4-aza-2-silacyclohexane shows a boiling point at 141.2°C at 1015 hPa.
Executive summary:

The boiling point to 2,2,4-Trimethyl-1-oxa-4-aza-2-silacyclohexane was determined with the method of distillation according to DIN 53171. The atmosphereic pressure at the time of measurement was 1015 hPa. The first drop of condensed product was seen at 141.2°C. In the repeat measurement the temperatures were 141.3°C (gas room) and 141 (liquid). The mean value of the gas room temperatures was 141.3°C. The corrected temperature according to Sydney-Young (with correction factor 0.035°C/hPa) is 141.2°C.
