Zinc acetate dihydrate Usage And Synthesis

Chemical Properties

Zinc acetate dihydrate Zn(C2H3O2)•2H2O is a Colourless or white efflorescent crystals; faint acetic acid odor; astringent taste; monoclinic crystals; density 1.735 g/cm3; loses water at 100°C; decomposes at 237°C; readily dissolves in water, 43g/100 mL at 20°C; soluble in alcohol.

Chemical Properties

Zinc acetate occurs as white crystalline, lustrous plates with a faint acetic odor and an astringent taste.

Uses

Zinc acetate is used as a mordant in dyeing textiles; in preserving wood; in manufacturing glazes for painting on ceramics; and as an analytic reagent in measuring albumin, tannin, and phosphate. Other uses are as a crosslinking agent for polymers; and as a supplement in food. The compound is used in medicine as an astringent.

Uses

Preserving wood; as mordant in dyeing; manufacture of glazes for painting on porcelain. As a reagent in testing for albumin, tannin, urobilin, phosphate, blood.

Uses

Zinc acetate [Zn(C2H3O2)2] is used as a mordant for dyeing cloth, as a wood preservative, as a laboratory agent, and as a dietary supplement.

Production Methods

Zinc acetate is synthesized by reacting zinc oxide with glacial acetic acid, with subsequent crystallization, separation by centrifugation, and drying and milling of the crystals. No organic solvents are used during the synthesis.

Pharmaceutical Applications

Zinc acetate has been used as an excipient in a variety of pharmaceutical formulations including topical gels, lotions, and solutions, and subcutaneous injections. It has also been investigated for use in an oral controlled-release formulation for water-soluble drugs in combination with sodium alginate and xanthan gum.
Therapeutically, zinc acetate has been used in oral capsules for the treatment of Wilson’s disease. Zinc acetate has also been demonstrated to be effective as a spermicide in vaginal contraceptives.

Safety

Zinc acetate is used in topical pharmaceutical formulations and subcutaneous injections, where it is generally regarded as relatively nontoxic and nonirritant when used as an excipient. However, zinc acetate is poisonous by intravenous and intraperitoneal routes; it is also moderately toxic following oral consumption.
LD50 (mouse, IP): 0.108 g/kg
LD50 (mouse, oral): 0.287 g/kg
LD50 (rat, IP): 0.162 g/kg
LD50 (rat, oral): 0.794 g/kg

storage

Zinc acetate loses water of hydration above 100℃. Zinc acetate should be stored in an airtight container in a cool, dry, place.

Purification Methods

It crystallises (in poor yield) from hot water or, better, from EtOH. [Beilstein 2 III 193, 2 IV 114.]

Incompatibilities

Zinc acetate is incompatible with oxidizing agents, zinc salts, alkalis and their carbonates, oxalates, phosphates, and sulfides.

Regulatory Status

Included in the FDA Inactive Ingredients Database (SC injections; topical lotions and solutions). Included in medicines licensed in the UK.
