  • Swelling of alkylammonium, montmorillonites

    Hiltner, Phyllis Anne, 1941-
    Abstract:
    Adsorption on a series of primary n-alkylammonium bentonites was studied by simultaneous gravimetric determination of the adsorption isotherm and X-ray diffraction measurement of the c-spacing. All adsorbates gave typical Type II isotherms. BET plots were linear in the region P/P[subscript o] = 0.10 - 0.35 and v[subscript m] values were...

  • Heats of immersion and swelling of quaternary ammonium complexes of montmorillonites

    St. Clair, Akos Dominic
    Abstract:
    Heats of immersion were obtained for four different organophilic clay complexes in a series of normal alcohol-heptane mixtures with alcohols of increasing chain length. The immersion calorimeter employed was the Dewar type with a sensitivity of approximately 5 x 10⁻⁵°C. Gel volumes were determined for two of the clay complexes...
