Abstract
The clay minerals, generally characterized by their small particle size, affinity for water, and response to chemical changes in their environment, are noted for their gelling and viscosity-increasing abilities in aqueous systems. Rendered organophilic by association with long-ohain organic compounds, several of the clay minerals exhibit similar or even greater gelling abilities in various organic liquids.
Methods of preparing organophilic clays are discussed and data shown for ion exchange reactions between long-chain organic cations and montmorillonite minerals. Properties of modified clays in various liquid systems are illustrated, and industrial applications are cited.
