The accuracy of the instrument was checked by determining the melting point of a certified sample of benzoic acid (certified melting point: 122.5 °C ± 0.3 °C). The results were:

First determination: 122.5 °C

Second determination: 122.3 °C

Boiling point determination 

First determination: observed boiling point: 254.4 °C

Second determination: observed boiling point: 255.4 °C

 

The atmospheric pressure at the time of the experiment was 96.89 kPa (Meteo Suisse). A correction of the temperature to normalised pressure (101.325 kPa) was made. The determination of this correction factor was made using the Sidney Young equation, as recommended in OECD guideline 103.

 

With this correction made, the standard boiling point of Benzyl Propionate was determined to be (values rounded off): 257 °C

Conclusions:

The boiling point was determined to be 257 °C at 1013.25 hPa.

Executive summary:

A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using the principle according to Siwoloboff. A small amount of the test item was filled in a capillary tube to a height of 5 mm and was heated in the electronically temperature controlled sample block. In a preliminary test a boiling point of 256.3 °C was observed. This value was introduced as expected boiling temperature for the main test. The sample was heated to 5 °C below the approximate boiling point, then at rate 0.5 °C/minute. The sample was observed visually for any possible changes in appearance, consistency and colour. The phase transition from liquid to vapour was deduced by the continuous formation of steam bubbles leaving the inserted boiling capillary. This determination was done in duplicate. A correction of the temperature to normalised pressure was done using the Sidney Young equation. The boiling point was determined to be 257 °C at 1013.25 hPa. No observations were made which cause doubt on the validity of the outcome of the study.

Additional information

A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using the principle according to Siwoloboff. The boiling point was determined duplicated using electronically temperature controlled sample block. The boiling point was corrected to normalised pressure using the Sidney Young equation. The boiling point was determined to be 257 °C at 1013.25 hPa.
