Abstract
Abstract An aluminum iodide is prepared by first forming a reactive aluminum and then contacting the reactive aluminum with iodine and a liquid organic compound. The reactive aluminum is formed by permeating in the presence of hydrogen ions highly pure aluminum with a metal having an atomic volume close to that of hydrogen. Aluminum organoiodides are useful for detergents, catalysts, surgical scrubs, and other diverse applications.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
A METHOD OF FORMING AN ALUMINUM ORGANOIODIDE COMPRISING THE STEPS OF FORMING A REACTIVE ALUMINUM BY PERMEATING HIGHLY PURE ALUMINUM IN THE PRESENCE OF A HYDROGEN ION SOURCE WITH ANOTHER METAL HAVING AN ATOMIC VOLUME CLOSE TO THAT OF HYDROGEN, AND SUBSEQUENTLY, REACTING THE REACTIVE ALUMINUM WITH A COMBINATION OF IODINE AND AN ORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALCOHOL, KETONE, ALDEHYDE, PHENOL, GLYCOL, AND CARBOXYLIC ACIDS WHEREBY SAID ALUMINUM ORGANOIODIDE IS FORMED.
