| Abstract: | Differential thermal analysis was employed as a new method to observe the formation of complexes of dibenzo-18-crown-6 polyether and macrocyclic nitro derivatives with potassium iodide. DTA thermograms of polyethers, of solid complexes, and mixtures of polyether and potassium iodide were obtained in an atmosphere of dry nitrogen. |
