Synthesis of Chromium (III) Phthalate via Chromium (VI) Oxide using Tertiary Amyl Alcohol

 [CrO2 (C8H5O4) (H2O) 3] and [CrO2 (C8H5O4) (H2O) 3] are two chromium complexes. By reducing CrO3 at room temperature with ethanol and phthalic acid (H2pht), a solution containing monomeric and dimeric Cr (III) complexes was produced. Both a 1:1 and a 1:2 molar ratio of H2pht to Cr in the solution is permanently stable against precipitation. While DSC looked at thermal behaviour, their analysis used elemental (C and H), ICP-OES (for Cr percent), UV-Vis, FTIR, 1HNMR, and Fast Atomic Bombardment (FAB) Mass spectrometry. The obtained results indicated that the complexes were presumably monomeric. It was noticed that altering the reaction conditions did not affect the type of the products; they just slowed down the reaction and the pace of complex formation. The kinetics and the lability of complexes could be predicted from the DSC.
