Vapour pressure at 25 °C: 2.25 * 10-06 Pa - Executive summary:
The vapour pressure of the test item ROC-601 was determined at eight different temperatures (30, 45, 60, 75, 90, 105, 120 and 135 °C) following EU A.4 using the effusion method (weight loss). Experiments 1 – 5 showed no relevant or reproducible weight loss. When visible contaminations, caused by explosive evaporation of the test item, were observed, the cells were meticulously cleaned and weighed. This weight was used as initial weight for the subsequent measurements. To avoid bias, these measurements were not used for calculations (First measurements of experiments 6 and 7).
Three experiments (at 105, 120 and 135 °C) could be evaluated as they showed relevant and reproducible weight loss. All evaluated experiments showed good reproducibility, giving relative standard deviations of less than 17 % and very good correlation.
Therefore, the result of the test can be considered valid.
For the test item ROC-601, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 1.39* 10-06 Pa
Vapour pressure at 25 °C: 2.25* 10-06 Pa
The linear regression of log P vs. 1/T gave a correlation coefficient r of -0.9999, showing good repeatability and precision. Therefore, the determination is considered as valid. No deviations from the study plan or from the guideline were ascertained.

*The samples were stored in an exsiccator after the weighings until start of the next measurement series due to organisational reasons.
Observations
60 °C: At the first measurement of the third experiment it was observed that the test item was completely melted.
105 °C: At the first measurement of the sixth experiment all vials were contaminated. Therefore, they were meticulously cleaned and weighed. To avoid bias these values were not used for calculation.
120 °C: At the first measurement of the seventh experiment all vials were slightly contaminated. Therefore, they were meticulously cleaned and weighed. To avoid bias these values were not used for calculation.
Calculation of Results
Equation
The vapour pressure was calculated using the following equation:
p = m / KAt (2 PiRT/M)E1/2
with the following equation parameters

The correction factor is depending on the relation length/radius of the aperture of the Knudsen cell. The following factors are stated in the literature (E.D.Cater, Ch.2A, Physicochem. Measurements in Metal Research, Part 1, R.A. Rapp, Ed., John Wiley, New York, 1970).

With the chosen length of the aperture 0.1 mm and the chosen radius 0.5 mm, a relation of 0.2 was calculated, and a correction factor of 0.909 was chosen.
Calculation of Results:
Experiments 1 – 5 yielded no relevant or reproducible weight loss. Therefore, they were not used for calculation.
All calculation results are given in the tables below and on the following pages.
In all tables, E-0X represents multiplication with 10-X.

In this table, E-0X represents multiplication with 10-X.
A graph with log P vs. 1/T was plotted. Since the values were correlated by a linear relation, the data could be fitted by linear regression.

Description of key information
The vapour pressure of the test item ROC-601 was determined at eight different temperatures (30, 45, 60, 75, 90, 105, 120 and 135 °C) following EU A.4 using the effusion method (weight loss). Whereas experiments 1 – 5 showed no relevant or reproducible weight loss, the results of experiments 6 - 7 could be evaluated as they showed relevant and reproducible weight loss. All evaluated experiments showed good reproducibility, giving relative standard deviations of less than 17 % and very good correlation (the linear regression of log P vs. 1/T gave a correlation coefficient r of -0.9999, showing good repeatability and precision.). Therefore, the result of the test can be considered valid.
For the test item ROC-601, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 1.39* 10-06 Pa
Vapour pressure at 25 °C: 2.25* 10-06 Pa
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
