Key result
Boiling pt.:
>= 175.5 - <= 176 °C
Atm. press.:
763 mm Hg

None

Conclusions:
The boiling point of d-limonene is 175.5-176 °C at 763 mm Hg.
Executive summary:

The boiling point of d-limonene is 175.5-176 °C at 763 mm Hg.

The reliability of this result has been considered as 2 (reliable with restrictions) because ‘The Merck Index’ is cited as a reference book containing peer reviewed data in the REACH Guidance Document R.7a.

Endpoint:
boiling point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Justification for type of information:
D-Limonene is one of the two isomers of dipentene. Therefore, data on dipentene can be used for extrapolation to d-limonene. See read-across justification document in section 13.
Reason / purpose for cross-reference:
read-across source
Key result
Boiling pt.:
>= 175.5 - <= 176.5 °C
Atm. press.:

None

Conclusions:
The boiling point of dl-limonene is 175.5-176.5 °C at 763 mm Hg.
Executive summary:

The boiling point of dl-limonene is 175.5-176.5 °C at 763 mm Hg.

The reliability of this result has been considered as 2 (reliable with restrictions) because ‘The Merck Index’ is cited as a reference book containing peer reviewed data in the REACH Guidance Document R.7a.

Endpoint:
boiling point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Justification for type of information:
L-Limonene is the S-isomer of d-limonene. Therefore, data on l-limonene can be used for extrapolation to d-limonene. See read-across justification document in section 13.
Reason / purpose for cross-reference:
read-across source
Key result
Boiling pt.:
>= 175.5 - <= 176.5 °C
Atm. press.:
763 mm Hg

None

Conclusions:
The boiling point of l-limonene is 175.5-176.5 °C at 763 mm Hg.
Executive summary:

The boiling point of l-limonene is 175.5-176.5 °C at 763 mm Hg.

The reliability of this result has been considered as 2 (reliable with restrictions) because ‘The Merck Index’ is cited as a reference book containing peer reviewed data in the REACH Guidance Document R.7a.

Description of key information

The boiling point of d-limonene at 101 kPa is between 176 and 178 °C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
176 °C

Additional information

In a weight of evidence approach, a range was given for the melting point of d-limonene, all literature values available being consistent and of the same order of magnitude.
