25 – 35	25.49	298.64	9.23±0.14	2.22±0.01

 

Conclusions:

Using the Static Technique, the vapour pressure of Hatcol 2352 at 20°C is:
P (20°C) = 4.9 ± 0.4 Pa = (3.7 ± 0.3) x 10E-2 mm Hg

Executive summary:

The determination of the vapour pressure of Hatcol 2352 was performed in accordance with the following guidelines:

European Economic Community (EEC), EEC directive 92/69 EEC, Part A, Methods for the determination of physico-chemical properties, A.4 'Vapour pressure", EEC Publication No. L383, December 1992.

Organisation for Economic Co-operation and Development (OECD), OECD guidelines for testing chemicals, Guideline NO.104: "Vapour pressure curve", July 27,1995.

 

Using the Static Technique, the vapour pressure of Hatcol 2352 at 20°C is:

P (20°C) = 4.9 ± 0.4 Pa = (3.7 ± 0.3) x 10^-2 mm Hg

 

According to the OECD guideline, the recommended range for the Static method is: 10 up to 10⁵ Pa. However, when using a capacitance manometer, the Static method can be used below 10^-1 Pa (according to guideline's paragraph 'Apparatus'). This study was performed using a capacitance manometer with a measurement range of 6 x 10^-3 Pa – 2 x 10⁵ Pa. The vapour pressures measured for Hatcol 2352 at the three test temperatures were all between 8 and 34 Pa.

All sensors, thermometers and pressure sensor heads were calibrated over the ranges used in the experiments. Pressure sensor heads were calibrated from high vacuum (<< 10^-5 Pa) to be read as "0"-value up to 1 Pa. The thermometers were calibrated in the measurement range used for testing.

The Static Technique was used for the determination of the vapour pressure at 20°C.

At the beginning of the test the vapour pressure of the test substance decreased slightly every next measurement, due to the removal of volatile impurities. After measurement 35 this decrease became negligible and the vapour pressure became stable. So from that moment on, the collected data were used for the determination of the vapour pressure of HatcoI 3344.
