A plot of log10 (vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 10 gives the following statistical data using an unweighted least squares treatment.

 

Slope  -4.61 x 103
Standard deviation in slope   26.7

 

Intercept         14.1
Standard deviation in intercept         8.54 x 10-2

 

The results obtained indicate the following vapor pressure relationship:

 

Log10(Vp (Pa)) = -4.61 x 103/temp(K) + 14.1

 

The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -1.41.

Applicant's summary and conclusion

Conclusions:
The vapor pressure of the test item has been determined to be 4.0 x 10E-2 Pa at 25 ºC.
Executive summary:

The determination was carried out using a procedure designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.

Principle of the Test

The vapor pressure was determined using a vapor pressure balance with measurements being made at several temperatures and linear regression analysis used to calculate the vapor pressure at 25 °C.

Summary of Results

 The values of vapor pressure at 25 °C extrapolated from each graph are summarized in the following table:
