2 Al + 3 Cl 2 → 2 AlCl 3 2 Al + 6 HCl → 2 AlCl 3 + 3 H 2. Aluminium chloride may be formed via a single displacement reaction between copper(II) chloride and aluminium. 2 Al + 3 CuCl 2 → 2 AlCl 3 + 3 Cu. In the US in 1993, approximately 21,000 tons were produced, not counting the amounts consumed in the production of aluminium. [7]
Sodium aluminate is manufactured by the dissolution of aluminium hydroxide (Al(OH) 3) in a caustic soda (NaOH) solution. Aluminium hydroxide can be dissolved in 20–25% aqueous NaOH solution at a temperature near the boiling point. The use of more concentrated NaOH solutions leads to a semi-solid product.

2 NaCl + 2 H 2 O → 2 NaOH + H 2 + Cl 2. Without a membrane, the OH − ions produced at the cathode are free to diffuse throughout the electrolyte. As the electrolyte becomes more basic due to the production of OH −, less Cl 2 emerges from the solution as it begins to disproportionate to form chloride and hypochlorite ions at the anode:
3 + NaOH → Al(CH 3 CO 2) 2 OH + 3 NaCl 2 CH 3 CO 2 Na + NaAlO 2 + 2 H 2 O → Al(CH 3 CO 2) 2 OH + 3 NaOH. An improved process using a combination of aluminium chloride and sodium aluminate with sodium acetate prepared in situ has been patented: [31] 29 NaAlO 2 + 10 NaOH + 84 CH 3 COOH + 13 AlCl 3 → 42 Al(CH 3 CO 2) 2 OH + 39 NaCl + 26 H 2 O
2 Al + 2 NaOH + 2 H 2 O → 2 NaAlO 2 + 3 H 2. Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO 2, Na 3 AlO 3, Na[Al(OH) 4], Na 2 O·Al 2 O 3 ...
A ring anion, the cyclic Al 6 O 18− 18 anion, found in tricalcium aluminate, Ca 3 Al 2 O 6, which can be considered to consist of 6 corner sharing {AlO 4} tetrahedra. [5] A number of infinite chain anions in the compounds Na 7 Al 3 O 8 which contains rings linked to form chains, Na 7 Al 13 O 10 and Na 17 Al 5 O 16 which contain discrete chain ...
Aluminium triacetate is a chemical compound that is prepared by heating aluminium chloride (AlCl 3) or Al powder with a mixture of acetic acid (CH 3 COOH) and acetic anhydride (C 4 H 6 O 3). [5] It is referred as the normal salt and is only made in the absence of water at a relatively high temperature like 180 °C. [1]
