Boiling point
Administrative data
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Not specified
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- The study was conducted in 1929 and therefore did not follow a specific guideline. The purpose of the study was the synthesis of 2,6-dimethyl-hexanethinoxid and then 2,6-dimethyl-hexan-ethenoxid (= Limetol). The substance was characterised using derivatisation techniques and ele-mental analysis. A specific method for measuring the boiling point was not reported, however the fact of reporting the pressure conditions for all the boiling points in the synthesis paper demon-strates the scientific rigour of the authors. Pressure for the boiling point determination of Limetol was standard atmospheric pressure, 760 mmmHg.

- Reference substance name:
- Automatically generated during migration to IUCLID 6, no data available
- IUPAC Name:
- Automatically generated during migration to IUCLID 6, no data available
- Test material form:
- not specified
- Details on test material:
- 2,6-dimethyl-hexan-ethenoxid (=Limetol) was synthesized from 2,6-dimethyl-hexan-ethinoxid by partial hydrogenation. Although outdated nomenclature is used in the paper, depicted structural formulae allow for unambiguous identification of the test substance. The test substance was characterised using derivatisation techniques and elemental analysis.
