Solvation of Montmorillonite

Journal of Pharmaceutical Sciences, 1972
It is known that polar solvents penetrate the montmorillonite lattice and that multiple layers of solvent can exist between the silicate layers. It is shown here that the number of layers in the interlaminar spacing is different when the clay is equilibrated with liquid than when it is equilibrated with vapor.

Electrokinetic Phenomena in Montmorillonite

MRS Proceedings, 2000
AbstractClays present remarkable electrokinetic features since they exist from very dilute colloidal state to nanoporous materials, according to the ration water/clay. The case of low volume fraction Vwater/Vtot which corresponds to compact systems is examined.

Implications of silylated montmorillonite on montmorillonite–polyacrylate nanocomposites

Applied Clay Science, 2011
Abstract New nanocomposites based on polyacrylates and five types of montmorillonites modified by edge covalent bonding, were obtained. The alkoxysilanic substituent strongly influenced the physical–chemical properties of the final material. All modified clay minerals exhibit a lower wettability compared to pure montmorillonite.

Stability of Montmorillonites: II. Aberdeen Montmorillonite

Soil Science Society of America Journal, 1971
Abstract Six montmorillonite samples from Aberdeen, Mississippi were equilibrated with various solutions for 3–4 years. Under the conditions of these experiments, Aberdeen montmorillonite was found to be less stable than Belle Fourche montmorillonite and kaolinite.

Effect of organophilic montmorillonite on polyurethane/montmorillonite nanocomposites

Journal of Applied Polymer Science, 2003
AbstractDifferent kinds of organophilic montmorillonite cotreated by cetyltrimethyl ammonium bromide (CTAB) and aminoundecanoic acid (AUA) were synthesized and applied to prepare polyurethane/montmorillonite nanocomposites via solution intercalation.

Montmorillonite and vanadia—montmorillonite catalysts for aniline alkylation

Journal of Molecular Catalysis, 1994
Abstract An efficient aniline alkylating property of montmorillonite and vanadia-montmorillonite is discussed in the light of acidity.

The surface energy of montmorillonite

Journal of Colloid and Interface Science, 2003
By combining the relation that describes pair interaction in binary mixtures with the Young equation, a formula is obtained for calculating the surface energy of montmorillonite as a function of the surface pressure, the surface tension of water, and the liquid/solid contact angle.

ACID ACTIVATION OF MONTMORILLONITE

Canadian Journal of Chemistry, 1960
A Pembina montmorillonite clay has been activated with sulphuric acid at various dosages by the conventional wet process and by the new "dry" process. The products are compared with respect to the fractions of the metal ion components remaining after leaching, the hydrated silica content, the bleaching capacity, and the B.E.T.
