염화알루미늄 C화학적 특성, 용도, 생산

물성

알루미늄 염화물 (AlCl3)은 알루미늄과 염소의 주요 화합물입니다. 흰색이지만 샘플은 종종 철 (III) 염화물로 오염되어 황색을 띄게됩니다. 주로 알루미늄 금속 생산에서 생산되고 소비되지만 많은 양은 화학 산업의 다른 분야에서도 사용됩니다. 화합물은 종종 루이스 산으로 인용됩니다. 그것은 Friedel-Crafts 반응 (아 실화 및 알킬화 모두)의 촉매제로서 화학 산업에서의 응용 분야를 발견합니다.

용도

염화 알루미늄은 많은 산업 분야에 사용됩니다. 그것은 많은 석유 화학 제품, 페인트 및 합성 고무를 만드는데 사용됩니다. 그것은 또한 물을 치료하는 데 사용됩니다.
염화 알루미늄의 가장 주목할만한 용도 중 하나는 방취제에 사용하는 것입니다. 염화 알루미늄은 일시적으로 땀샘을 막아 모공을 막는 젤을 형성합니다. 이 땀샘이 막히면 땀샘이 방지됩니다.

화학적 성질

White or yellowish crystals. The vapor consists of double molecules Al 2 Cl 6 . Soluble in water.

화학적 성질

Aluminum chloride is a noncombustible but highly reactive whitish-gray, yellow, or green powder or liquid. Strong, acidic, irritating odor like hydrochloric acid

용도

Astringent (topical).

용도

A yellowish-white crystalline or granular powder made by passing chlorine gas over alumina in a heated state and collecting the product by sublimation. Aluminum chloride was occasionally used in gold and platinum toning baths.

정의

aluminium chloride: A whitishsolid, AlCl3, which fumes in moist airand reacts violently with water (togive hydrogen chloride). It is knownas the anhydrous salt (hexagonal; r.d.2.44 (fused solid); m.p. 190°C (2.5atm.); sublimes at 178°C) or the hexahydrateAlCl3.6H2O (rhombic; r.d.2.398; loses water at 100°C), both ofwhich are deliquescent. Aluminiumchloride may be prepared by passinghydrogen chloride or chlorine overhot aluminium or (industrially) bypassing chlorine over heated aluminiumoxide and carbon. The chlorideion is polarized by the smallpositive aluminium ion and thebonding in the solid is intermediatebetween covalent and ionic. In theliquid and vapour phases dimer moleculesexist, Al2Cl6, in which thereare chlorine bridges making coordinatebonds to aluminium atoms (seeformula). The AlCl3 molecule can alsoform compounds with other moleculesthat donate pairs of electrons(e.g. amines or hydrogen sulphide);i.e. it acts as a Lewis acid. At hightemperatures the Al2Cl6 molecules inthe vapour dissociate to (planar)AlCl3 molecules. Aluminium chlorideis used commercially as a catalyst inthe cracking of oils. It is also a catalystin certain other organic reactions,especially the Friedel–Craftsreaction.

반응 프로필

ALUMINUM CHLORIDE behaves as an acidic salt. Self-reactive. After long storage in closed containers, explosions often occur upon opening [Chem. Abst. 41:6723d 1947]. Can cause ethylene(also other alkenes) to polymerize violently [J. Inst. Pet. 33:254 1947]. Causes ethylene oxide to rearrange and polymerize, liberating heat [J. Soc. Chem. Ind. 68:179 1949]. Can catalyze violent polymerization of allyl chloride [Ventrone 1971]. Addition to nitrobenzene containing about 5% phenol caused a violent explosion [Chem. Eng. News 31:4915 1953]. Mixtures with nitromethane may explode when organic matter is present [Chem. Eng. News 26:2257 1948].

위험도

Powerful irritant to tissue; moderately toxic by ingestion. Reacts violently with water, evolving hydrogen chloride gas.

건강위험

Contact with the skin or eyes in the presence of moisture causes thermal and acid burns.

화재위험

Behavior in Fire: Reacts violently with water used in extinguishing adjacent fires

인화성 및 폭발성

Aluminum chloride is not flammable but reacts violently with water, so fires involving this substance should be extinguished with carbon dioxide or dry chemicals. Toxic fumes (HCl and reaction products) can be released during fires.

공업 용도

Aluminium chloride (AlCl3) is a volatile solid which sublimes at 458 K. The vapour formed on sublimation consists of an equilibrium mixture of monomers (AlCl3) and dimers (Al2Cl6). It is used to prepare the powerful and versatile reducing agent lithium tetrahydridoaluminate (LiAlH4). Aluminium trichloride (AlCl3) act as Lewis acids to a wide range of electron-pair donors, and this has led to their widespread use as catalysts. In the important Friedel-Crafts acylation, AlCl3 is used as a strong Lewis acid catalyst in order to achieve the acylation of an aromatic ring.

공업 용도

Ammonium sulfate (NH4)2SO4 is a white, crystalline salt obtained by reacting ammonia and sulfuric acid. This compound is used as a depressant for sphalerite during flotation of complex copper–lead–zinc ores. In plant practice, it is used in a number of concentrators in Mexico, specifically the San Martin operation, treating Cu–Pb–Zn ores containing pyrrhotite. Ammonium sulfate also improves floatability of copper and lead using xanthate collector at pH 7.5–9.0.

Safety Profile

Moderately toxic by ingestion. Experimental teratogenic and reproductive effects. Mutation data reported. The dust is an irritant by ingestion, inhalation, and skin contact. Highly exothermic polymerization reactions with alkenes. Incompatible with nitrobenaenes or nitrobenzene + phenol. Highly exothermic reaction with water or steam produces toxic fumes of HCl. See also ALUMINUM COMPOUNDS, CHLORIDES, and HYDROCHLORIC ACID.

잠재적 노출

It is used as ethylbenzene catalyst, dyestuff intermediate, and detergent alkylate; in making other chemicals and dyes, astringents, deodorants, in the petroleum refining, and the rubber industries

효소 저해제

This tervalent inorganic ion, derived from its parent Group IIIB metal, readily forms the amphoteric species aluminum hydroxide [Al (OH) 3] that hydrates to the insoluble hexacoordinate species [Al (OH) 3 (H2O) 3]. Insolubl–e aluminum hydroxide can be fo3+rmed by the addition of 3h+ydroxide ion, OH to form a soluble salt of Al (Reaction: [Al (H2O) 6] (aq) + 3 OH– (aq) → Al (H2O) 3 (OH) 3 (s) + 3 H2O (l). The insoluble metal hydroxide can act as a base, since it can be redissolved upon reaction with an acid (Reaction: Al (OH) 3 (H2O) 3 (s) + 3 H3O+ (aq) → [Al (H2O) 6]3+ (aq) + 3 H2O (l) ). Alternatively, the metal hydroxide can act as an acid, since it can react with a base (Reaction: Al (OH) 3 (H2O) 3 (s) + OH– (aq) → [Al (OH) 4 (H2O) 2] (aq) + H2O (l) ). pH therefore strongly influences the aqueous species that form, as does temperature and ionic strength. Nature of Enzyme-Bound Aluminum Ions: The amphoteric nature of aluminum ions is strongly influenced by the presence of other ligands, including amines, carboxylic acids, and phosphoric acid species. For this reason, the best way to determine the enzyme-bound species is through the use of X-ray crystallography or NMR structures of the enzyme-aluminum species in a buffer that approximates the solution properties used in assays of enzymatic activity. Because the enzyme is likely to provide one or more ligands, the precise solution species that first combines with the enzyme is necessarily conjectural. Aluminum Exposure & Neurodegenerative Disease: Various lines of evidence, mostly conjectural, have associated aluminum exposure to such disorders as dialysis encephalopathy, amyotrophic lateral sclerosis, Parkinson Disease in the Kii Peninsula and Guam, and Alzheimer's disease (AD). The complex characteristics of aluminum bioavailability make it difficult to evaluate its toxicity, and a direct causal relationship remains to be established. Given that protein misfolding and associated oligomerization and/or polymerization appears to be an emerging theme in protein folding disorders, one cannot discount a role of aluminum ions in promoting such protein structural rearrangements. Sources: Anhydrous AlCl3 (Sigma-Aldrich 563919 and Fisher-Acros AC36481-0100 (both are 99.999% trace metals basis); CAS 7446-70-0; MWanhydrous = 133.34 g/mol); AlCl3 Hydrate (Sigma-Aldrich 229393 (99.999% on trace metals basis); CAS 10124-27-3). Caution: Anhydrous AlCl3 reacts violently with water, generating considerable heat. The recommended practice for hydrolysis is to allow anhydrous AlCl3 to hydrate slowly (over a few days) in a moist atmosphere. This can be accomplished by placing two beakers, one containing the anhydrous powder and the other a few mL of water in an otherwise empty desiccator. (The anhydrous powder essentially serves as the desiccant.) Another simple method is to expose a weighed sample of anhydrous powder to the ambient atmosphere for a few days, allowing it to absorb ambient humidity. Unless highly experienced, it is advisable to prepare only a small quantity (0.2-0.5 g) at a time.

응급 처치

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy
