Patent ID: 7060258

Claim:
A method of making solid activated aluminum-zirconium composition having a metal/chloride ratio of about 1.2 to about 1.3 comprising: i) heating 8–20% by weight basic aluminum halides or nitrate of the formula: Al 2 (OH) 6-a X a wherein X is Cl, Br or NO 3 , wherein a is from about 1 to 1.5 from 50° C., to about reflux for about 2 to 20 hours and cooling to RT, mixing with small amount of AlCl 3 or HCl or a mixture there of AlCl 3 and HCl at about RT for a period of about 5 minutes to about 30 minutes, ii) mixing with the solution of a zirconium glycine compound of the formula: ZrO(OH) b X 2-b A c wherein b is a numerical number from 0 to 0.7, X is Cl, Br or NO 3 , A is an amino acid, c is a number from 0.8 to about 1.2 and iii) drying the blended solution of (i) and (ii) to a solid.
