Physical, Thermal, and Optical Characterization of Rhodium (3) Acetylacetonate.

Abstract

Rhodium (III) acetylacetonate was investigated for its physical, thermal and optical properties. Ultraviolet-visible absorption spectra show absorption at 320 nm, 260 nm, and 210 nm. Density measurements yielded a value of 1.75 gram/cm cubed. Thermal characteristics were evaluated using differential thermal analysis(DTA). It was found that the compound is not volatile, decomposing upon heating. If heating rates are slower, decomposition is complete below the melting point. If the compound is annealed at 267 C for four hours decomposition is complete, yielding 99% pure rhodium metal. In an oxidizing atmosphere, on the other hand, the compound decomposes into a product containing 75% rhodium which appears to be RhO2. Keywords: Organometallic Decomposition, Rhodium Acetylacetonate, Organometallic Properties.
