Conclusions
-
1.
Mesoporous silica gel with 20 nm pore diameter may be taken as a practical model of nonporous amorphous silica, according to the liquid immersion heats.
-
2.
The heats of wetting of the hydrated amorphous silica surface by normal aliphatic alcohols and hydrocarbons are independent of the number of carbon atoms in the molecules and are 220 and 65 mJ/m2, respectively.
-
3.
The interphase (liquid-solid) surface layer or normal alcohol molecules on silica gel is a Langmuir palisade with the OH alcohol groups directed toward the silica surface.
