Experimental confirmation of a new invariant for a non-linear chemical reaction
The first non-Onsager thermodynamic invariant for a non-linear chemical system was found experimentally in all domains using "the dual kinetic experiment" in a batch reactor in which the reaction of esterification of ethanol with acetic acid was studied jointly with the reaction of hydrolysis of ethyl acetate. In a typical experiment, a glass flask was loaded with 200 mL of 1 mol/L ethanol and acetic acid in acetonitrile for esterification or 1 mol/L ethyl acetate and water in acetonitrile for hydrolysis at 20, 30, and 40 degrees C. The obtained experimental result is a justification of the theory presented previously (Constales et al., 2012). (C) 2018 Elsevier Ltd. All rights reserved.
