Description

White crystals or powder with strong odor of hydrogen chloride; [HSDB] Pure material is deliquescent solid. Commercially available as anhydrous, the hexahydrate and as 16.5%, 28%, and 80% solutions; [CHEMINFO]

Sources/Uses

Used as a catalyst and chemical intermediate; Aluminum chloride hexahydrate is used to preserve wood, to disinfect stables and slaughterhouses, to dye fabrics, to develop photos, to refine crude oil, and to manufacture parchment paper; It is used in deodorants and antiperspirants; [HSDB]

Comments

Hydrogen chloride gas and hydrochloric acid released upon contact of Al-Cl3 with moisture; Corrosive to the eyes, skin, and respiratory tract; Inhalation of dust or released HCl can cause acute pulmonary edema; [CHEMINFO] Occupational asthma confirmed by specific challenge testing in a foundry worker; [Malo] Experiments show that "there is essentially no HCl gas formation; the substance is quite unreactive." Contact with the anhydrous substance causes thermal and acid burns. [CAMEO] See "Aluminum."

Restricted

Use as a registered pesticide was cancelled; [HSDB]
