Specific Surface Determination of Expansible Layer Silicates.
The vacuum-oven technique for quantitative sorption of a glycerol duointerlayer by montmorillonite at 35 degrees C is adapted to 130 degrees C to obtain a mono-inter-layer of glycerol, glycerol vapor relative pressure being controlled by temperature differential. Values obtained for montmorillonite agree closely with theoretical values based on liquid glycerol density, while vermiculite retains a mono-interlayer of somewhat less than liquid glycerol density.
