Atm. press.:
1 atm
Remarks on result:
other: Atm. pressure is not reported, only supposed
Conclusions:
Boiling point of l-limonene is between 175.5 and 176 °C.
Executive summary:

Boiling point of l-limonene was reported to be between 175.5 and 176 °C. It is an experimental value but the reliability is not assignable because the data come from secondary literature.

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

Weight of evidence: Boiling point at ca. 101 kPa : 176 - 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 melting point of l-limonene is calculated consistent with all values reported for the two enantiomers (d- and l-limonene) being in the same order of magnitude.
