Abstract

Reactions of zirconium tetrachloride with pivalic acid in benzene, toluene, m- and o-xylene, and in excess pivalic acid at the boiling temperature of a solvent were studied. The product of reactions in aromatic solvents was found to have the composition corresponding to the formula Zr2O(Piv)6. The reaction in excess pivalic acid resulted in the formation of the compound Zr(Piv)4. The reaction products were investigated by X-ray powder diffraction, IR and NMR spectroscopy, and their physicochemical properties were compared with those of zirconium tetrapivalate synthesized by a mechanically activated solid-phase reaction between ZrCl4 and sodium pivalate.
