    • The phase equilibrium of alkanes and supercritical fluids 

      Schwarz, Cara Elsbeth (Stellenbosch : University of Stellenbosch, 2001-12)
      Current methods for wax fractionation result in products with large polydispersity, and due to the high temperatures required, thermal degradation of the wax is often incurred. The need for an alternative process thus ...

    • The processing of wax and wax additives with supercritical fluids 

      Schwarz, Cara Elsbeth (Stellenbosch : University of Stellenbosch, 2005-12)
      Waxes have many potential uses but large-scale application is hampered by their virtual insolubility. By grafting the wax with a polyethylene glycol segment to form an alcohol ethoxylate, the solubility of the wax in ...
