Remarks on result:
other: 3.69 X 10-11 Pa at 25°C

The boiling point of FAT36034/G was calculated to be approximately 483 °C using Meissner's method. The calculation based on the structure of the main component of FAT36034/G. The contribution of molar refraction (Rd) and parachor (Pa) in the calculation of the boiling point of FAT36034/G. The vapor pressure of FAT36034/G was estimated to be 3.69 X 10-11Pa at 25 °C based on the boiling point calculated and using the Modified Watson Correlation.

Conclusions:
The vapor pressure of FAT 36034/G was estimated to be 3.69 x 10E-11 Pa (0.0000000000369 Pa) at 25 °C temperature based on the boiling point calculated and using the Modified Watson Correlation.
Executive summary:

The estimation of the vapor pressure of FAT 36034/G was based on the EEC directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.4 "vapor Pressure" , EEC Publication No. L383, December 1992 and the OECD Guideline No. 104, "vapour Pressure", adopted July 27,1995. Based on the structure of the main component of FAT 36034/G and using the Modified Watson Correlation the boiling point and vapor pressure of FAT 36034/G were calculated. The boiling point was calculated to be approximately 483 °C and the vapor pressure of FAT 36034/G was estimated to be 3.69 x 10E-11 Pa (0.0000000000369 Pa) at 25 °C temperature based on the boiling point calculated and using the Modified Watson Correlation
