Zirconium(IV) carboxylates

Abstract

Zirconium(~v) carboxylates, Zr(OOCR)4 where R = Me, Et, CHZCl, CHCl, and CCI,, have been prepared by the reaction of zirconium(~v) chloride and carboxylic acids. The compounds have been characterized by elementary analyses, thermogravimetry and infrared spectral data. The compounds are non-electrolytes in nitrobenzene and probably have polymeric structures.

Influence of cleaning methods on bond strength to saliva contaminated zirconia

“…42 However, this salt is prone to hydrolysis. 44,45 The results of this study showed that, regardless of saliva Phosphate-based end of 10-MDP forms a bond with zirconia whereas methacrylate-based end forms a bond with resin cements. 46 It was suggested that 10-MDP containing primer applied on zirconia would expose the hydrophobic methacrylate ends of the bound 10-MDP molecules which would increase the hydrophobicity of the zirconia surface.…”

“…ZP forms a carboxylate salt through ionization of carboxylic acids upon application on Y‐TZP surface . However, this salt is prone to hydrolysis . The results of this study showed that, regardless of saliva contamination, cleansing with ZP significantly improved bond strength of SAC to zirconia surfaces ( P < .05).…”

Preparation of Zirconium Oxide Powder Using Zirconium Carboxylate Precursors

“…One of the most widely used precursors for the synthesis of zirconia may be zirconium acetate-based ones [8][9][10][11][12][13]. For example, zirconium tetraacetate can be prepared by the reaction of zirconium tetrachloride with an excess of acetic acid at 80 ∘ C [8]. Refluxing the mixture to the boiling point produces the formation of zirconium oxyacetate [8,9].…”

“…The latter can be prepared straightforwardly by the reaction of sodium carboxylate with an aqueous solution of a zirconium salt [7], leading to the linking of zirconium cations to the carboxylate anions. One of the most widely used precursors for the synthesis of zirconia may be zirconium acetate-based ones [8][9][10][11][12][13]. For example, zirconium tetraacetate can be prepared by the reaction of zirconium tetrachloride with an excess of acetic acid at 80 ∘ C [8].…”

“…For example, zirconium tetraacetate can be prepared by the reaction of zirconium tetrachloride with an excess of acetic acid at 80 ∘ C [8]. Refluxing the mixture to the boiling point produces the formation of zirconium oxyacetate [8,9]. Zirconium oxyacetate, Zr 4 O 3 (CH 3 COO) 10 ⋅3H 2 O, can be also prepared by refluxing of a small amount of zirconium oxychloride with acetic acid [14].…”
