Study Guidelines
The present study was conducted according to:
EC, 2009: The Commission Regulation (EC) No 761/2009 of 23 July 2009 laying down Test Methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), A.4. “Vapour Pressure”, Official Journal No L 220, 24/08/2009.OECD, 2006: The Organisation for Economic Co-operation and Development (OECD) Guidelines for the Testing of Chemicals, OECD 104 Vapour Pressure, adopted by the Council on March 23, 2006.
U.S. EPA, 1996: The United States Environmental Protection Agency (EPA), Product Properties Test Guidelines, OCSPP 830.7950 “Vapour Pressure” (EPA 712-C-96-043), August 1996.
Methodology
Determination of Vapour Pressure (Effusion Method using TGA)
Quantities of 13.3135, 20.9216, and 18.3280 mg test item was added one at a time to the balance pan of the instrument for replications I, II and III, respectively. The balance pan was allowed to stand for 5 minutes to get stabilised. After the balance was stabilized, the reading was recorded electronically.
The temperature scanning was started from 130 to 140 °C at a rate of 1 °C/minute using nitrogen as purging gas @ 50 mL/minute. The mass (mg) and the temperature reading (°C) were recorded automatically into a computer file and printed. The readings of temperature and mass recorded in °C
and mg were converted into Kelvin (K) and kilogram (kg), respectively. The experiment was performed in triplicate and the mean value was reported.Results
The mean Log10 [Vp (Pa)] of Finester 2009 was -5.27. The vapour pressure of
Finester 2009, at 20 °C, was 5.370 × 10-6 Pa.
