Applicant's summary and conclusion
- Conclusions:
- From the determined results, it was concluded that the Vapour pressure of Cyanogen Bromide was 15.46 kPa at 25.1°C
- Executive summary:
The Present study was conducted to determine the Vapour pressure of Cyanogen Bromide by sponsored by Libor Bachura Vyzkum A Vyroba at Bioscience Research Foundation, India by following OECD 104 guideline.
The study was conducted using Gas saturation method. In the preliminary test, the study was conducted at three different flow rates (0.030, 0.036 and 0.042 m3/hours) at 25.1°C. The desorption efficiency of the test apparatus was determined to be 99.67%. In the preliminary test, the sample was collected at different time intervals viz., 12, 14 and 16 hours. At three different flow rates, the mass of the vaporized test substance was determined to be 327 g at saturation level. A definitive test was conducted and the Vapour pressure of the test substance was determined to be 15.46 kPa at 25.1°C.
