Zirconium(IV) isopropoxide
Synonym: Zirconium(4+) propan-2-olate, Zirconium tetraisopropoxide, Zr(OiPr)4
CAS Number 2171-98-4 | EC Number 218-522-4
Zirconium(IV) isopropoxide, also known as zirconium tetraisopropoxide or (i-PrO)₄Zr, is an organometallic compound characterized by the molecular formula Zr(C₃H₇O)₄ and a molecular weight of 387.67 g/mol. This substance appears as white crystals and is highly sensitive to moisture, necessitating storage in a dry, inert environment to maintain stability. The compound features zirconium in the +4 oxidation state coordinated with four isopropoxide ligands, forming a robust molecular structure ideal for various applications in synthesis and materials science.
Applications in Organic and Inorganic Synthesis
Due to its reactivity and well-defined structure, zirconium(IV) isopropoxide is commonly used as a precursor in the production of high-purity zirconium oxides and other zirconium-based compounds. In organic and inorganic synthesis, it acts as an efficient catalyst or reagent, particularly valuable in sol-gel processes and the preparation of nanomaterials. Its applications extend to coating technologies, where it aids in the creation of thin films and protective layers essential in electronics and optical devices.
Handling and Storage Precautions
As a flammable solid with sensitivity to moisture, zirconium(IV) isopropoxide must be handled under controlled, inert conditions. The compound should be stored away from any moisture sources and kept in tightly sealed containers to prevent decomposition. Additionally, handling zirconium tetraisopropoxide requires standard laboratory safety equipment, including gloves, eye protection, and well-ventilated spaces, to mitigate any exposure risks associated with its reactivity.
Industrial and Laboratory Applications
In industrial and research contexts, zirconium isopropoxide serves a critical role in the synthesis of advanced ceramics, high-performance materials, and catalysts. It is especially significant in chemical vapor deposition (CVD) and sol-gel applications, where its stability and reactivity enable the formation of zirconium-based coatings, ceramics, and thin films. Its use in nanomaterial production further underscores its versatility in developing next-generation materials for technological and scientific advancements.
Zirconium(IV) isopropoxide and benzyl alcohol in tetrahydrofuran (THF), methyl methacrylate (MMA), and styrene (St) were used for the synthesis of Zirconia nanocrystals. A new and simple method has been developed to synthesize large quantities of highly monodisperse tetragonal zirconia nanocrystals. In this synthesis, a nonhydrolytic sol-gel reaction between zirconium(IV) isopropoxide and zirconium(IV) chloride at 340 °C generated 4 nm-sized zirconia nanoparticles. See links below
