摘要: Abstract Reversible adsorption isotherms at different temperatures have been used to study the system of water adsorbed on Aerosil and whose surface has partially methylated with trimethylchlorosilane. The change in shape isotherm upon methylation from type II III, according Brunauer's classification, renders difficult calculation capacity monolayer; however, this case it can be obtained by Kaganer's method. variation mobility monolayer shown comparing experimental theoretical integral entropies, while molecules multilayer region always a high degree freedom.
