The results may represent rounded-off values obtained by calculations based on the exact raw data.

A total of 10 runs were completed for the main sequence. Equilibrium with regard to vapor pressure was assessed to have been reached over the final 4 runs. Thus the final 4 runs have been used to calculate the definitive vapor pressure value for the test item.

Conclusions:
The vapor pressure of 2-Propenoic acid, 2-[[(octadecylamino)carbonyl]oxy]ethyl ester is 6.8 x 10-4 Pa at 25 ºC.
