Additional information

The estimation of the vapour pressure of FAT 40825/A was based on the EEC directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.4 "Vapour Pressure", EEC Publication No. L383, December 1992 and the OECD Guideline No. 104, "Vapour Pressure", adopted July 27, 1995.

The boiling point of FAT 40825/A was calculated to be approximately 897 °C using Meissner's method. The vapour pressure of FAT 40825/A was estimated to be 1.73×10-32 Pa at 25 °C based on the boiling point calculated and using the Modified Watson Correlation.
