Three endothermic heat effects were observed at about 84°C, 121°C and 212°C. After the experiment, the sample had completely evaporated (heating rate of 20°C/min from 25°C to 400°C). For the interpretation of the endothermic heat effects a capillary test was carried out between 25°C and 400°C with a heating rate of 10°C/min. Boiling could be observed starting at about 211°C. The atmospheric pressure during the measurements was 99.8 kPa.
In order to determine the boiling point more precisely, further DSC-runs were recorded between 150°C and 250°C with a heating rate of 5°C/min. In the first main test run, the boiling range was determined to be between 207.5°C and 217.7°C and in the second main test run between 194.3°C and 211.3°C. After the measurements both samples had completely evaporated. In conclusion, the boiling range of the test substance was determined to be between 200.9°C and 214.5°C (which is equal to 474.1 K and 487.7 K). The atmospheric pressure during the measurements was 99.8 kPa.

The boiling point of Tetrahydrolinalyl acetate was determined to be between 200.9°C and 214.5°C (The atmospheric pressure during the measurements was 99.8 kPa). The determination of the the boiling point / boiling range of the test item was performed according to the EEC Directive 92/69, A.2 “Boiling temperature“, December 1992 and to the OECD Guideline No. 103: “Boiling Point“, adopted July 27, 1995.
