Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- other: company data
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Result from experimental data with calculated values.
- Justification for type of information:
- Company data which is considered reliable.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: Industry internal technical procedure
- Principles of method if other than guideline:
- Distillation of N-(tert-butyl)benzylamine during a reaction process. The distillation was done under vaccum on the reaction product ie not a boiling point of the 'pure' already distilled material.
- GLP compliance:
- no
- Type of method:
- other: no data
- Specific details on test material used for the study:
- Crude, purity > 90.0%
- Key result
- Boiling pt.:
- > 192 - < 209 °C
- Atm. press.:
- 101.3 kPa
- Remarks on result:
- other: observed results adjusted to atmospheric pressure
- Conclusions:
- The boiling point of the crude substance (purity > 90.0%) was calculated to be > 192 to < 209°C at atmospheric pressure. This is a lower result than reported literature values after convertion to equivalent units.

Description of key information
The boiling point at atmospheric pressure is affected by impurities and converstion of observed distillation temperatures and pressures.
Based on data and experimental error (and without carrying out additional testing) the boiling point minimum is estimated to be 190°C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 190 °C
Additional information
The experimental boiling point range for the crude substance during two batches was > 192 - < 209°C.
The estimated boiling point is 227.2 °C, as given by EPI-Suite (v4.11) using MPBPVP (v1.68).
Literature reported values (listed in SciFinder) calculate to 207.7 - 274.8°C when adjusted to atmosphieric pressure with the average value being 224.2°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
