Chemische Eigenschaften

Blue powder.Soluble in acids and ammonium hydroxide; insoluble in water.

Verwenden

In manufacture of rayon, battery electrodes, other Cu salts; as mordant in dyeing; as pigment; in fungicides, insecticides; as feed additive; in treating and staining paper; in preparation of Schweitzer's reagent; in catalysts.

Allgemeine Beschreibung

The orthorhombic nature of copper hydroxide crystals was determined by X ray diffraction. Copper hydroxide can act as a heterogeneous catalyst in the selective oxidative cross coupling of terminal alkynes to yield their corresponding ynamides.

Hazard

Toxic by ingestion and inhalation.

m?gliche Exposition

Inorganic copper fungicide, nematicide, and microbiocide

Versand/Shipping

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Inkompatibilit?ten

Reacts with calcium (metal hydroxides), nitroethane, nitromethane, 1-nitropropane, zirconium

Waste disposal

Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill Copper-containing wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. Details of copper recovery from a variety of industrial wastes have been published. If recovery is not feasible, the copper can be precipitated by the use of caustics and the sludge deposited in a chemical waste landfill. Recommendable methods: Precipitation, solidification, landfill, discharge to sewer, & incineration. Peer-review: Precipitate copper with alkali, filter, solidify precipitate. (Do not use ammonia as alkali). Cation exchange will allow recovery of copper. Eluate from cation exchanger can be passed through anion exchanger to remove (or reduce) naphthenic acid content. Exhausted ion exchange resins can be landfilled. (Peer-review conclusions of an IRPTC expert consultation)
