The boiling temperature and the respective
vapour pressure were measured during this study. Based on the
experimental results, the vapour pressure curve In Pvp versus 1/T was
plotted. The vapour pressure of 3- mercaptopropanoic acid methyl ester
(MMP) at 25 degrees C was extrapolated from the determined values for
each test. The extrapolated vapour pressure of the first experiment was
2.28 x 10 hPa, which is equal to 2.28 x 10^2 Pa at 25 deg. C. The second
test indicates a vapour pressure at 25 degrees C of 3.44 x 10 hPa, which
is equal to 3.44 x 10^2 Pa.
The vapour pressure of 3-mercaptopropanoic
acid methyl ester (MMP) at 25 degrees C was calculated as the mean from
both experiments to be: 2.86 x 10^2 Pa at 25 degrees.
