  • Patent number: 5120522
    Abstract: The present invention relates to a process for preparing basic aluminum compounds having the general formula (1)[Al.sub.2 (OH).sub.x Cl.sub.y (SO.sub.4).sub.z ].sub.n (1)where:n is at least equal to 1x=2-4.0y=2.0-3.40z=0-0.30andx+y+z=6by means of a reaction of alumina with hydrochloric acid, possibly mixed with sulfuric acid. The alumina is caused to react in alumina/acid(s) stoichiometric conditions to obtain the compounds of formula (1). The reaction is carried out by milling alumina in liquid phase under heavy stirring.
