Key result
Boiling pt.:
> 150 °C
Atm. press.:
101.3 hPa
Decomposition:
no
Remarks on result:
not determinable
Remarks:
not distilled at 150 degree celcius at 1 atm. pressure. The sample degraded above 150 degree celcius
Conclusions:
Boiling point of Toluene-4-sulphonohydrazide (CELLCOM-H) was determined by distillation in accordance to OECD TG 103.
No boiling was observed at 150 oC and 101.3 KPa. Thus, the boiling point of the test item could not be determined. The sample degraded above 150 degree Celcius.
Executive summary:

Boiling point of Toluene-4-sulphonohydrazide (CELLCOM-H) was determined by distillation at the temperature 0-150oC and 101.3 KPa. Distilled water was used for calibration giving 100oC under 101.3 KPa with a tolerance 100 +/- 0.5oC. The test was in accordance to OECD TG 103.

No boiling was observed at 150oC and 101.3 KPa. Thus, the boiling point of the test item could not be determined. The sample degraded above 150oC.

Description of key information

Boiling point of Toluene-4-sulphonohydrazide (CELLCOM-H) was determined by distillation at the temperature 0-150oC and 101.3 KPa. Distilled water was used for calibration giving 100oC under 101.3 KPa with a tolerance 100 +/- 0.5oC. No boiling was observed at 150oC and 101.3 KPa. Thus, the boiling point of the test item could not be determined. The sample degraded above 150oC (423K).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
150 °C
