Accuracy checking

The accuracy of the instrument was checked by determining the melting point of a certified sample of benzoic acid (certified boiling point: 122.2°C).

First determination: 122.1°C to 122.3 °C.

Second determination: 122.2°C to 122.4 °C.

 

Boiling point determination

First determination: observed boiling point: 307.7 °C.

Second determination: observed boiling point: 307.6 °C.

 

Correction to normalized pressure

The atmospheric pressure at the time of the experiment was 96.46 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.

 

T_n= T + (f_T Δp)

 

Where: Δp = 101.325 kPa - p

p = pressure in kPa; the pressure was obtained from the Swiss meteorological service for the time of the experiment.

f_T = rate of change of boiling temperature with pressure in K/kPa, here a value of 0.47 K/kPa, as published in DIN 53171, was used.

T = temperature in K

T_n = normal boiling point

With this correction made, it can be concluded that the standard boiling point of test item is 583.1 K (309.9 °C).

Conclusions:

The boiling point of test item was measured according to OECD Guideline No. 103 (principle according to Siwoloboff). The boiling point of test item is 583.1 K (309.9 °C).

Executive summary:

The boiling point of test item was measured according to OECD Guideline No. 103 (principle according to Siwoloboff) using an electronically controlled heating device.

 

The standard boiling point (corrected for atmospheric pressure: 101.325 kPa) of test item is 583.1 K (309.9 °C).

Description of key information

Boiling point of test item was determined as 583.1K (309.9°C) (extrapolation).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

309.9 °C
