This implies that hydrogen chloride is lost in the evaporation of AlCl solutions and the residue is a basic salt (in this case an "oxychloride") in place of AlCl. This type of reaction is also seen with other metal chlorides such as ZnCl, SnCl, FeCl and lanthanide halides such as DyCl. With some compounds such as TiCl, the hydrolysis may go to completion and form the pure hydroxide or oxide, in this case TiO.
