황산아연 MSDS


Zinc sulfate heptahydrate

황산아연 C화학적 특성, 용도, 생산

화학적 성질

Colorless crystals, small needles, or granular, crystalline powder; without odor; astringent, metallic taste. Efflorescent in air. Solutions acid to litmus. Loses 7H2O at 280C. Soluble in water and glycerol; insoluble in alcohol.

용도

zinc sulfate is a cosmetic astringent and biocide produced through the reaction of sulfuric acid with zinc. It can cause irritation to the skin and mucous membranes, and may cause an allergic reaction.

용도

Preparation of complexometric titrant

용도

As mordant in calico-printing; preserving wood and skins; with hypochlorite for bleaching paper; manufacture of lithopone and other zinc salts; clarifying glue; electrodepositing Zn; also as reagent in analytical chemistry.

용도

Zinc sulfate (ZnSO4?7H2O) is also known as zinc vitriol or white copper. In addition to being used to make rayon, zinc sulfate is used as a wood preservative, a dietary supplement, an animal feed, and as a mordant to prevent dyes from running in printed textiles. It can also be used to stanch bleeding.

정의

ChEBI: A hydrate that is the heptahydrate form of zinc sulfate.

상표명

Verazinc (Forest).

농업용

Zinc sulphate heptahydrate (ZnSO4?7H2O), also called white vitriol, is the most common form of zinc sulphate.
It forms zinc sulphate monohydrate above 70°C and anhydrous salt at 280°C, and is used as a mordant and a styptic (to check bleeding).

공업 용도

Zinc sulfate (ZnSO4·7H2O) is a white powder, very soluble in water (i.e. 37% at 20 °C). Zinc sulfate is primarily used in base-metal flotation as a depressant for sphalerite. Zinc sulfate has been used to depress talc in by-product molybdenum circuit.

Safety Profile

Human poison by an unspecified route. Poison experimentally by subcutaneous, intravenous, and intraperitoneal routes. Moderately toxic by ingestion. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of SOx and ZnO. See also ZINC SULFATE.

Purification Methods

Crystallise it from aqueous EtOH or dilute H2SO4 below 39o when it forms the heptahydrate, and between 39o and 70o it forms the hexahydrate, and above 70o the monohydrate is stable. The anhydrous salt is obtained from the hydrates by heating at 280o or lower temperatures in a current of dry air. It decomposes to ZnO and SO2 at 767o. The solubility of the heptahydrate in H2O is 5.88% at 0o, 61.92% at 30o, 66.61% at 35o and 70.05% at 39o.
