THERMOELECTRIC AND DIELECTRIC INVESTIGATIONS OF THE THERMOCHROMISM OFVARIOUS NA-ACETYLACETONATE PHASES AND INTERMEDIATES

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