Thermoelectric and dielectric investigations of the thermochromism of various Na-acetylacetonate phases and intermediates

Abstract Sodium acetylacetonate was prepared by the interaction of sodium metal with acetylacetone. A fresh sample and various samples preheated at various temperatures were carefully prepared. Measurements were made by x-ray diffraction, IR absorption spectroscopy and differential thermal analysis (DTA). The temperature dependence of the electrical and dielectric properties of selective batches of Na-acetylacetonate phase and intermediates was measured.
