Key result
Boiling pt.:
ca. 342 °C
Remarks on result:
other: ± 2°C
Conclusions:
The boiling point of the test substance, Terpenes and Terpenoids, turpentine-oil, limonene fraction, polymers with 1-methyl-4-(1-methylethenyl)cyclohexene and turpentine-oil β-pinene fraction terpenes, was determined to be 342 ± 2°C (615 ± 2K).
Executive summary:

The boiling point of the test substance, Terpenes and Terpenoids, turpentiune-oil, limonene fraction, polymers with 1 -methyl-4 -(1 -methylethenyl)cyclohexane and turpentine oil β-pinene fraction terpenes was determined via differential scanning calorimetry following a process compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No. 440/2008 (30 May 2008), Method 103 of the OECD Guide;ines for Testing of Chemicals (27 July 1995) and Method 830.7220 of the OCSPP Guidelines (August 1996).

The instrument used was a Mettler Toledo DSC822e Differential Scanning Calorimeter (DSC), which was tested prior to the experiment with indium and zinc for its temperature accuracy. It was found to be within the defined tolerances amd therefore the instrument was considered acceptable for use. Aliquots of the test material were placed in pre-pierced aluminium crucibles and then underwent a 25 -450°C thermal programme at 20°C/min. After heating to 450°C, there was no visible residue remaining at the end of the test.

The boiling point of the test substance was determined to be 342 ± 2°C (615 ± 2K).
