'''Uranyl zinc acetate''' (ZnUO<sub>2</sub>(CH<sub>3</sub>COO)<sub>4</sub>)is a compound of [[uranium]].

Uranyl zinc acetate is used as a laboratory reagent in the determination of [[sodium]] concentrations of solutions using a method of quantitatively precipitating sodium with uranyl zinc acetate and [[Gravimetric analysis|gravimetrically]] determining the sodium as uranyl zinc sodium acetate, (UO<sub>2</sub>)<sub>2</sub>ZnNa(CH<sub>3</sub>OO)-6H<sub>2</sub>O. This method was important to determine Na in [[urine]] for [[diagnostic]] purposes. Zinc uranyl acetate is sometimes called "sodium reagent"  since pale yellow NaZn(UO<sub>2</sub>)<sub>3</sub>(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)<sub>9</sub> is one of the very few insoluble sodium compounds.

The process for catalytic synthesis of toluene-2,4-diisocyanate (TDI) from [[dimethyl carbonate]] (DMC) consists of two steps. Starting from the catalytic reaction between toluene-2,4-diamine (TDA) and DMC, dimethyl toluene-2,4-dicarbamate (TDC) is formed, and then decomposed to TDI. For the first step, the yield of TDC is 53.5% at a temperature of 250 °C, over Zn(OAc)2/alpha–Al2O3 catalyst. For the second step, the yield of TDI is 92.6% at temperatures of 250–270 °C and under pressure of 2.7 kPa, over '''uranyl zinc acetate''' [[catalyst]], when di-n-octyl sebacate(DOS) is used as heat-carrier, and a mixture of [[tetrahydrofuran]] (THF) and [[nitrobenzene]] is used as solvent.
