| description | Processes are provided for preparing basic aluminum compounds of Formula I: Al2(OH)6-aXa (I) wherein X is Cl-, Br-, F-, I-, SO4= or NO3- and a is about 0.9 to 4, the compound being characterized by size exclusion chromatography as having a Band I percent aluminum value of about 5% or less and a Band II percent aluminum value of about 50% to 90%, which comprise (a) suspending an aluminum metal in an aqueous medium to form a slurry, (b) applying ultrasonic energy to the slurry, (c) reacting the sonicated slurry with an aluminum compound of Formula II AlnXm (II) or an acid of Formula III: HnX (III) wherein X is Cl-, Br-, F-, I-, SO4= or NO3-, n is 1 or 2 and m is 3, at a temperature of about 45 DEG C. to 100 DEG C. to form a reaction product. |
