other: boiling point: 219.3±0.4ºC

Preliminary study: The average value of an initial boiling point was approximately 210.0°C when heated at 10.0°C per minute in the range of 50-400°C.

Table 1. Measured values of the boiling temperature and boiling point of Laevo alpha terpineol

Sample	Atmospheric pressure, hPa	Boling temperature,^oC	Boiling point,^oC
1	1015.2	219.7	219.6
2		218.9	218.9
3		219.5	219.4
Average values ± standard deviations,^oC		219.4 ± 0.4	219.3 ± 0.4

3 series of boiling point measurements were performed in the following temperature ranges: sample 1: 200.0 - 400.0°C, samples 2 and 3: 209.0 - 400.0. The heating rate was 1.0 °C/min.

The table includes the average value of boiling temperature (value measured) and boiling point (value corrected according entered barometric pressure).

In this study the accuracy of the apparatus was equal to 0.5°C.

Conclusions:

The boiling point of the test item is 219.3ºC at atmospheric pressure (1015.2 hPa).

Executive summary:

The determination of the boiling point was carried out according to OECD Guideline No. 103 and EU method A.2 (GLP study). A preliminary study was performed in order to determine the boiling temperature range of the test item. A method according to Siwoloboff was used with the BÜCHI Melting Point M-565 apparatus. The measurements were performed in three samples of the test item. The boiling point of the test item, as average, was determined to be 219.3±0.4ºC under atmospheric pressure of 1015.2 hPa.

Additional information

Key study: The determination of the boiling point was carried out according to OECD Guideline No. 103 and EU method A.2 (GLP study). A preliminary study was performed on the test item. A method according to Siwoloboff was used with the BÜCHI Melting Point M-565 apparatus. Three samples were tested. The boiling point of the test item was determined to be 219.3±0.4ºC (average value) under atmospheric pressure of 1015.2 hPa.

Supporting study: A comparable reported boiling point of 220ºC for laevo alpha terpineol is available from a peer review handbook.
