PINZON B, Jorge Alejo. SUSPENSIONS VISCOSITY OF A NATURAL AND ORGANOPHILIC BENTONITE. Rev.Colomb.Quim. [online]. 2006, vol.35, n.2, pp.225-232. ISSN 0120-2804.

It was studied the suspensions viscosity of a bentonite, from the CaucaValley, related to the solids content, in natural state with water and modified with benzyldimethyltetradecylammonium ions with ethanol- glycerine mixture at 25 °C. For the natural bentonite the function : Viscosity vs. % of solids is lineal, but for the organophilic bentonite is parabolic. The mathematical function: Specific viscosity /%of solids vs,%of solids is a polynomial of grade two as the suspensions of the natural bentonite as well as the organophilic one. None of theses cases the Einstein, Dougherty-Kreiger or Farris ecuations is followed.

Keywords : Bentonite; organophilic compounds; viscosity; suspensions.
