Kupferoxid Chemische Eigenschaften,Einsatz,Produktion Methoden

Synthese

In 2 l Wasser werden 250 g (1 mol) Kupfersulfat-Pentahydrat gel?st. Zu der klaren L?sung werden portionsweise 80 g (1 mol) trockenes Natriumhydroxid hinzugegeben. Bei zu rascher Zugabe kann sich die L?sung ?rtlich so stark erw?rmen, dass hei?e laugenhaltige Flüssigkeit herausspritzt. Nach beendeter Zugabe wird kurz umgerührt und bis zum Sieden erhitzt. Die Wassermenge ist so gew?hlt, dass die L?sung nicht zu dickflüssig ist und deshalb beim Sieden nicht spritzt, was bei geringeren Wassermenge der Fall sein kann. Nach einigen Minuten Siedens ist das zuerst gebildete blaue Kupfer(II)-hydroxid zu schwarzem Kupfer(II)-oxid zerfallen. Man l??t die L?sung einige Zeit lang stehen, damit sie sich etwas abkühlt und das Kupfer(II)-oxid zu Boden sinkt. Die L?sung wird nun filtriert, wobei die Verwendung von mehreren (beispielsweise drei) gro?en Trichtern mitsamt Filtern zu empfehlen ist. Beim Ausgie?en der L?sung in die Filtern achtet man darauf, dass zun?chst die überstehende, relativ klare Flüssigkeit durch die Filter l?uft und dann erst der schwarze Bodensatz. Reste des Bodensatzes werden mit zus?tzlichem Wasser in einen Filter bef?rdert. Ist ein Gro?teil der Flüssigkeit aus dem Filter gelaufen, so wird das im Filter befindliche Kupfer(II)-oxid viermal mit Wasser gewaschen, wobei jedesmal der Filter vollst?ndig gefüllt wird. Dies ist notwendig um Natriumsulfat und Natronlauge-Reste auszuspülen. Man bel??t die Filter über nacht in den Trichtern, breitet sie auf einer ebenen Fl?che aus und gibt den feuchten Kupfer(II)-oxid-Brei mit Hilfe eines Spachtels in eine feuerfeste Schale. Nun wird der Brei bis zur v?lligen Trockene im Ofen erhitzt.

Beschreibung

Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.Mainly used in wood preservatives, ceramics, and mineral supplements for animal feed.
Copper(II) oxide nanoparticles (NPCuO) have industrial applications as antimicrobial agents in textiles and paints, and catalysts in organic synthesis. They may also be produced from electronic wastes. Cupric oxide poses potential health and environmental concern due to toxic and mutagenic particles generating reactive oxygen species.

Chemische Eigenschaften

Black fine free powder

Verwenden

Cupric Oxide can be used as a dietary ingredient and as a nutrient. Copper aids in the absorption of iron, in the formation of red blood cells and the proper bone formation and maintenance.
As pigment in glass, ceramics, enamels, porcelain glazes, artificial gems; in manufacture of rayon, other Cu Compounds; in sweetening petroleum gases; in galvanic electrodes; as flux in metallurgy; in correcting Cu deficiencies in soil; as optical-glass polishing agent; in antifouling paints, pyrotechnic compositions; as exciter in phosphor mixtures; as catalyst for organic reactions; in high tempereture superconductors.

Definition

A black solid prepared by the action of heat on copper(II) nitrate, hydroxide, or carbonate. It is a basic oxide and reacts with dilute acids to form solutions of copper(II) salts. Copper(II) oxide can be reduced to copper by heating in a stream of hydrogen or carbon monoxide. It can also be reduced by mixing with carbon and heating the mixture. Copper(II) oxide is stable up to its melting point, after which it decomposes to give oxygen, copper(I) oxide, and eventually copper.

Reaktionen

Copper(II) oxide dissolves in mineral acids such as hydrochloric acid, sulfuric acid or nitric acid to give the corresponding copper(II) salts:
CuO + 2 HNO3 → Cu(NO3)2 + H2O
CuO + 2 HCl → CuCl2 + H2O
CuO + H2SO4 → CuSO4 + H2O
It reacts with concentrated alkali to form the corresponding cuprate salts:
2 MOH + CuO + H2O → M2[Cu(OH)4]
It can also be reduced to copper metal using hydrogen, carbon monoxide, or carbon:
CuO + H2 → Cu + H2O
CuO + CO → Cu + CO2
2 CuO + C → 2Cu + CO2
When cupric oxide is substituted for iron oxide in thermite the resulting mixture is a low explosive, not an incendiary.

benefits

Cupric oxide is an oxide of the mineral copper. It is an essential element needed by the body to perform a host of functions.
Cupric oxide is used by specific enzymes to help in the production of energy, to create collagen and elastin, to metabolize iron, and in many functions of the brain and central nervous system. Cupric oxide is found in health supplements such as vitamins and health aid treatments.
Copper is a mineral that is needed in the body in small doses but has the ability to become toxic at high levels. Additional supplements of copper beyond what you should get in your normal diet should be discussed with a doctor.

Allgemeine Beschreibung

Copper oxides (Cu2O, CuO) are p-type semiconductor materials with small band gap energy. High physical and chemical stability of metal oxide nanoparticles renders them extremely useful in catalytic applications.The structures of the compounds are monoclinic. Nanoscaled copper oxide compounds can be prepared by thermal plasma technology. A study reports its antimicrobial properties.

Health Hazard

Exposures to copper fume cause fever, chills, muscle aches, nausea, dry throat, coughing, weakness, lassitude, irritation to the eyes, nose, throat, skin, upper respiratory tract, chest tightness, nose bleed, edema, and lung damage. Symptoms of copper fume poisoning also include metallic or sweet taste, skin itching, skin rash, skin allergy, and a greenish color to the skin, teeth, and hair. Workers have increased risk of Wilson’s disease.

Vorsichtsma?nahmen

Occupational workers should use protective clothing, such as suits, gloves, footwear, and headgear, and promptly change the contaminated clothing/work dress. Workers should not eat, smoke, or drink where copper dust or powder is handled, processed, or stored. Workers should wash hands carefully before eating, drinking, smoking, or using the toilet. The workplace should have a vacuum or a wet method facility to reduce the metal dust during cleanup
