Aluminium monochloride is the metal halide with the formula AlCl. This compound is produced as a step in the Alcan process to smelt aluminium from an aluminium-rich alloy. When the alloy is placed in a reactor that is heated to 1,300°C and mixed with aluminium trichloride, a gas of aluminium monochloride is produced.[2]

2[Al]{alloy} + AlCl3{gas} -> 3AlCl{gas}

It then disproportionates into aluminium melt and aluminium trichloride upon cooling to 900°C.

This molecule has been detected in the interstellar medium, where molecules are so dilute that intermolecular collisions are unimportant.[3]
