Instead HCl is lost leaving aluminium hydroxide or alumina (aluminium oxide):

[Al(H2O)6]Cl3 → Al(OH)3 + 3 HCl + 3 H2OLike metal aquo complexes, aqueous AlCl3 is acidic owing to the ionization of the aquo ligands:

[Al(H2O)6]3+ ⇌ [Al(OH)(H2O)5]2+ + H+Aqueous solutions behave similarly to other aluminium salts containing hydrated Al3+ ions, giving a gelatinous precipitate of aluminium hydroxide upon reaction with dilute sodium hydroxide:

AlCl3 + 3 NaOH → Al(OH)3 + 3 NaCl

Synthesis
Aluminium chloride is manufactured on a large scale by the exothermic reaction of aluminium metal with chlorine or hydrogen chloride at temperatures between 650 to 750 °C (1,202 to 1,382 °F). 2 Al + 3 Cl2 → 2 AlCl3
2 Al + 6 HCl → 2 AlCl3 + 3 H2Aluminium chloride may be formed via a single displacement reaction between copper chloride and aluminium metal. 2 Al + 3 CuCl2 → 2 AlCl3 + 3 CuIn the US in 1993, approximately 21,000 tons were produced, not counting the amounts consumed in the production of aluminium.Hydrated aluminium trichloride is prepared by dissolving aluminium oxides in hydrochloric acid. Metallic aluminium also readily dissolves in hydrochloric acid ─ releasing hydrogen gas and generating considerable heat. Heating this solid does not produce anhydrous aluminium trichloride, the hexahydrate decomposes to aluminium hydroxide when heated:

[Al(H2O)6]Cl3 → Al(OH)3 + 3 HCl + 3 H2OAluminium also forms a lower chloride, aluminium(I) chloride (AlCl), but this is very unstable and only known in the vapour phase. Natural occurrence
Anhydrous aluminium chloride is not found as a mineral. The hexahydrate, however, is known as the rare mineral chloraluminite.
Lack of access to sanitation, medical care, and psychosocial resources has been linked to increased mortality.A 2006 Turkish study reported that blood sugar levels were elevated in 46 percent of patients diagnosed with Fourniers. Another study reported that about one third of patients were alcoholic, diabetic, and malnourished, while another ten percent had been immunosuppressed through chemotherapy, steroids, or malignancy.Fournier gangrene is a rare side effect of SGLT2 inhibitors (canagliflozin, dapagliflozin, and empagliflozin), which increase the excretion of glucose in the urine. Diagnosis
Fournier gangrene is usually diagnosed clinically, but laboratory tests and imaging studies are used to confirm diagnosis, determine severity, and predict outcomes. X-rays and ultrasounds may show the presence of gas below the surface of the skin. A CT scan can be useful in determining the site of origin and extent of spread. Treatment
Fournier gangrene is a urological emergency requiring intravenous antibiotics and debridement (surgical removal) of dead tissue. In addition to surgery and antibiotics, hyperbaric oxygen therapy  may be useful and acts to inhibit the growth of and kill the anaerobic bacteria. Multiple wound debridement may be required in cases with extensive tissue involvement. Simple reconstructive procedures following wound debridement yield satisfactory outcomes in majority of the cases. Prognosis
While recent case series (n=980) studies have found a mortality rate of 20–40%, a large (n=1641) 2009 study reported a mortality rate of 7.5%. Epidemiology
A 2009 epidemiological study found the incidence of Fournier gangrene to be 1.6 cases per 100,000 males, in the United States.
