Descrizione

Descrizione generale

Zinc acetate dehydrate is an organic zinc salt. Its enthalpy of formation has been studied using solution calorimetry. Its vibrational spectra has been analyzed. It decomposes into ZnO (zinc oxide) nanoparticles which has been investigated using time-of-flight secondary ion mass spectrometry (TOF-SIMS). A study on the crystalline structure has revealed that it is monoclinic with space group C₂/c.

Applicazioni

Zinc acetate dehydrate was used as seeds to grow ZnO nanorods on the microfibers of PET (polyethylene terephthalate) fabric.
It may be used in the synthesis of layered Zn-arylphosphonates with potential application in sorption, ion exchange or catalysis. Also it may be used in the ultrasonic preparation of zinc sulfide nanoparticles coated on silica particles.
