Chemisorption of water at high temperatures on kaolinite: effect on dehydroxylation.
The dehydroxylation reaction of kaolinite in a vacuum at 425 degrees C is halted by introducing a water vapor pressure of 47 mm-Hg, and is resumed when the vacuum is reestablished. The sample gains weight corresponding to an approximately monomotecular layer of water on the kaolinite surface. At the temperatures and vapor pressures involved, the sorption is considered to be a chemisorption process.
