What is Cupric hydroxide?

Chemical properties

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

Chemical properties

Blue, gelatinous or amorphous powder. Insoluble in water.

The Uses of Cupric hydroxide

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.

The Uses of Cupric hydroxide

Used as a raw material in chemical processing and catalyst manufacturing. Copper(II) hydroxide is used as ceramic colorant. In organic synthesis, it is used as a catalyst to prepare 1-((2-aminoethyl)amino)anthraquinone, 1-amino-4-((2-aminoethyl)amino)anthraquinone by reacting with 1-bromoanthraquinone or 1-amino-4-bromoanthraquinone respectively. It is involved in the synthesis of benzoic acid and octanoic acid. It is used as a precursor in the production of rayon, battery electrodes and other copper salts It is also used as a dye mordant, paper colorant, pigment and feed additive.

What are the applications of Application

Copper(II) hydroxide is a compound also known as Comac parasol

General Description

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.

Potential Exposure

Inorganic copper fungicide, nematicide, and microbiocide

Shipping

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

Incompatibilities

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)
