Caffeine sublimates because it has a relatively low vapor pressure at room temperature, allowing it to transition directly from a solid to a gas without passing through a liquid phase. This phenomenon occurs due to the molecular structure of caffeine, which allows its molecules to escape into the vapor phase under certain conditions. Sublimation is more pronounced in substances with weaker intermolecular forces, and caffeine's structure facilitates this process. Consequently, when exposed to heat or reduced pressure, caffeine can readily sublime.
caffeine will normally sublime around 180 degree C (at 1 atm).
if you are looking at this you must be at the absolute stage of being bored.
it is used because some organic compounds do not sublime at atmospheric pressure so by using the vacuum it substantially reduces the pressure so that they can be purified by sublimation. it also makes decomposition and melting less likely to occur during the sublimation.
