The present invention relates to a process for preparing basic aluminum compounds having the general formula (1): [Al2 (OH)x Cly (SO4)z]n where: n is at least equal to 1, x = 2 DIVIDED 4.0, y = 2.0 DIVIDED 3.40, z = 0 DIVIDED 0.30, and x + y + z = 6, by 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. |
