Additional information

The substance decomposes before melting/boiling starting at 170 °C. Thus, the study does not need to be conducted. Nevertheless an estimation of the vapour pressure of the substance is available.

The vapour pressure of the test item was evaluated in a calculation according to the OECD Guideine 104 (1995) and the EU Method A.4 (1992). As the vapour pressure of the test item was predicted to be too low, it could not be subjected to experimental studies such as the gas saturation method, so it was evaluated using the Modified Watson Correlation as described by Lyman et al. (1981), which calculates the vapour pressure of a substance using its known boiling point. The boiling point of the test item was first calculated, and found to be > 700 °C using Meissner's method (Lyman et al., 1990). During the determination of the melting point / melting range, an exothermic effect was observed at about 170 °C, probably caused by decomposition or reaction of the test item, thus a second boiling point was determined as greater than 170 °C. Vapour pressure of the test item was additionally calculated using 170 °C as its boiling point value.
