The Gattermann reaction (also known as the Gattermann formylation and the Gattermann salicylaldehyde synthesis) is a chemical reaction in which aromatic compounds are formylated by a mixture of hydrogen cyanide (HCN) and hydrogen chloride (HCl) in the presence of a Lewis acid catalyst such as aluminium chloride (AlCl 3).

A substance is anhydrous if it contains no water.Many processes in chemistry can be impeded by the presence of water; therefore, it is important that water-free reagents and techniques are used.
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
Aluminum chloride hexahydrate, sold under the brand name Hydrosal Gel among others, is a first-line treatment for excessive sweating. [1]Clinical studies support the efficacy and low incidence of irritation of the 15% aluminum chloride and 2% salicylic acid gel base formula.
The nomenclature of organic acid anhydrides is derived from the names of the constituent carboxylic acids. In symmetrical acid anhydrides, only the prefix of the original carboxylic acid is used and the suffix "anhydride" is added.
Aluminium monochloride, or chloridoaluminium is the metal halide with the formula AlCl. Aluminium monochloride as a molecule is thermodynamically stable at high temperature and low pressure only. [2]
