Procedure

Aluminum isopropylate is prepared by reacting in a dry 2 liter flask swept with nitrogen, 231 ml. of isopropyl alcohol and 14 g. of aluminum in presence of a small amount of HgCl2. The reaction starts immediately and is maintained by heating under reflux. After 1 hour the isopropyl alcohol in excess is eliminated. After that, the aluminum isopropylate is distilled under 6 mm. of Hg at about 150° C. The distillate crystallizes very slowly. It contains 133 g. of aluminum per kg.
