The (liquid + liquid) and (solid + liquid) phase equilibria of nine binary mixtures containing fragrance raw materials (FRM) such as aliphatic ketones and compounds based on cyclohexane with water were investigated The systems (2-heptanone or 2-nonanone or 2-undecanone or 2-tridecanone or cyclohexyl carboxylic acid (CCA) or cyclohexyl acetic acid (CAA) or 2-cyclohexyl ethanol (2CE) or cyclohexyl acetate (CA) or 2-cyclohexyl ethyl acetate (2CEA) + water (2)) have been measured by a dynamic method in wide range of temperatures from (290 to 360) K and ambient pressure For all systems immiscibility in the liquid phase was detected The experimental data was correlated by means of the NRTL equation utilizing parameters derived from the (liquid + liquid) equilibrium Additionally the binary mixtures were predicted with the Mod UNIFAC (Do) model with known from literature parameters with very good results (C) 2010 Elsevier Ltd All rights reserved
