- Executive summary:
The vapour pressure of solid sample Test Material JPR BLUE 100 was determined on the 1st- 2nd September 1993 using the vapour pressure balance.
The solid sample was maintained below 202.25 °C during measurements & did not visibly appear to have changed at the temperatures used. There was no condensation onto the balance pan. The sample is quoted as 95.2% pure and with a melting point of greater than 370 °C.
During pump down there was some initial degassing of the sample. In Run 1 the mass differences rose hesistantly from an initial measured value of 1.8 μg at 24.6 °C (equivalent to 2.3 X 10-3Pascals region) to 86 .5 μg (equivalent to around 1.1 X 10-1Pascals) at 167.25 °C before decreasing over some 12 minutes to 62 .5 μg as the temperature was further raised to 193.5 °C. On cooling to 178.25 °C the mass difference was 4.6 μg compared with the earlier regime of around 70 μg. Because of the evident degassing, data could not be used to produce a reliable room temperature vapour pressure by extrapolation. The purity of 95.2% should be noted here and subsequently.
After overnight pumping the initial measured value of Run 2 was 0.40 μg at 24.9 °C (equivalent to 5.2 X 10-4Pascal region) varying slowly and erratically to yield a value of 10 .04 μg at 201.5 °C. The mass difference then decreased to 8.48 μg at 201.25 °C over a 5 minute period. Degassing is evident from the form of the vapour pressure relationship but, at the highest temperatures, values are similar in comparison with the previous run. Because of the problems encountered, a room temperature vapour pressure value could not be reliably extrapolated.
In Run 3 the initial measured mass difference value was 0.30 μg at 135.6 °C (equivalent to 3.9 X 10-4Pascal region) with values rising to 9.54 μg (equivalent to around 1.24 X 10-2Pascals) at 202.25 °C . Again because of the degassing problems encountered and the sample purity, vapour pressure values extracted by extrapolation were not used.
In all runs the continued degassing is evident and in no case could an adequate extrapolation be made.
In view of this the initial data of Run 3(0.30 μgat 135.6 °C) was used with a -2000 slope for the vapour pressure relationship to yield the rounded result
Vp (25 °C) = 6 X 10-6Pascals
to be taken as a satisfactory assessment of maximum vapour pressure.
