- Specific details on test material used for the study:
- Name: Selenium Disulphide
Batch No.: PMC / 285 / 16
CAS No.: 7488-56-4
Certificate of Analysis Date: January 23, 2017
Aggregate State at Room Temperature: Solid
Colour: Orange/yellow
Assay: 100% w/w UVCB material
Retest Date: November 24, 2019
Storage Conditions at Test Facility: At 20 °C ± 5 °C, in the dark - Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.001 Pa
- Conclusions:
- The isothermal thermogravimetric effusion method was applied for the determination of the vapour pressure of Selenium Disulphide.
A value of the vapour pressure of the test item was determined using the data obtained between 110 °C and 170 °C.
The vapour pressure of the test item was calculated (mean of three determinations) to: 5.41 × 10-4 Pa at 20 °C. - Executive summary:
The purpose of the study was to determine the vapour pressure of the test item using the isothermal thermogravimetric effusion method. The evaporation rates of the test item at elevated temperatures and ambient pressure were determined by monitoring the weight loss over the time.
This study was based on the procedures indicated by the following internationally accepted methods and was conducted in a GLP compliant laboratory:
- European Community (EC), EC No. 761/2009, Part A: Methods for the Determination of Physico-Chemical Properties, Guide-line A.4: “Vapour Pressure”, Official Journal of the European Union No. L220, August 24, 2009
- Organisation for Economic Co-operation and Development (OECD), OECD Guidelines for the Testing of Chemicals No. 104: “Vapour Pressure”, March 23, 2006
A value of the vapour pressure of the test item was determined using the data obtained between 110 °C and 170 °C. The vapour pressure of the test item was calculated (with the mean of three replicates) to: 5.41 × 10-4 Pa at 20 °C.
Reference
The evaluation of the vapour pressure was done with the reproducible weight loss values above ≥ 1 µg/min and with the results above 120 °C.
The plot of log VT of the test item as function of the reciprocal temperatures. The coefficient of correlation (R2) was 0.9975.
The regression line of log PT as a function of log VT used for calibration. The coefficient of correlation (R2) was 0.9945. The resulting equation was:
Inserting the equation for log VTabove, the following equation for the temperature dependence of the vapour pressure of the test item is obtained:
Log PT= C + D (a x *1000/T) + B) = C + (D x b) + (D x a x 1000)/T
(where: a = -3.8889, b = 6.1825, C = 4.7300 and D = 1.1279)
With this equation, a following vapour pressure results were obtained: 5.41 × 10-4Pa at 20 °C.
Remarks: In the case of the Selenium Disulphide it should be taken into consideration, that the test item is 100% UVCB material
