Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- In-house method based similar to EU Method A.2 (Siwoloboff method).
- Principles of method if other than guideline:
- Melting point is defined as the temperature at which a substance changes from the solid to the liquid state. During this transformation, most substances are changing their optical characteristics. Using this method the samples are scanned by a light source. Photocells, sensitive to the changes of light transparency of the samples during the melting process, will register the resulting indications on the control unit. The Melting Point M-565 is an instrument for automatic and visual (manual) determination of melting point, melting range, and boiling point at ambient temperatures +10 °C up to 400 °C. The melting point of three samples can be determined at the same time. The boiling point can be determined for one sample at a time. Samples can be observed through the lens or on the color display.
- GLP compliance:
- not specified
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 173 °C
- Atm. press.:
- 1 atm
- Conclusions:
- The boiling point of alpha-Terpinene was determined used in-house methods according to the Siwoloboff method. The boiling point was determined to be 173 °C.
- Executive summary:
The boiling point of alpha-terpinene was determined used in-house methods according to the Siwoloboff method. The boiling point was determined to be 173 °C.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
