Safety (MSDS) data for uranyl zinc acetate



Synonyms: zinc bis(acetato-O)dioxouranate, zinc uranyl acetate
Molecular formula: ZnUO4(CH3COO)2
CAS No: 10138-94-0
EINECS No: 233-390-8

Physical data

Appearance: yellow crystalline solid
Melting point:
Boiling point:
Vapour density:
Vapour pressure:
Density (g cm-3):

Explosion limits:
Autoignition temperature:
Water solubility: soluble


Stable. Incompatible with strong oxidizing agents.


Very toxic if swallowed or inhaled. Danger of cumulative effects - possible carcinogen, mutagen or teratogen. (Unenriched uranium compounds, while radioactive, typically have low radioactivity, so their toxicity is determined principally by their chemical nature.)

Personal protection

Safety glasses, gloves, good ventilation. Treat as a possible carcinogen.

5. Fire-fighting measures

Special risks:

Not readily combustible.

The following may develop in event of fire: radioactive dust.

Suitable extinguishing media:

Water spray, foam, dry powder or carbon dioxide

6. Accidental release measures

Wear appropriate protective clothing. Inform others to keep at a safe distance.

Mix solids with wet sand and absorb liquids on an inert absorbent, and transfer carefully to sealed

container. Arrange for removal by disposal company. Wash site of spillage thoroughly with water and


For large spillages liquids should be contained with sand or earth and both liquids and solids transferred

to salvage containers. Any residues should be treated as for small spillages.

7. Handling and storage


Observe national regulations.

Wash hands and face thoroughly after working with material. Contaminated clothing should be

removed and washed before re-use.


Observe national regulations.

Store at room temperature (15 to 25C recommended).

Keep locked up and in metal outer container.
