Claim 1
Independent Claim
87 words
A METHOD OF INITIATING A REACTION BETWEEN ISOPROPYL ALCOHOL AND ALUMINUM AT ATMOSPHERIC PRESSURE WHICH COMPRISES THE STEPS OF (A) INTRODUCING ALUMINUM, ALUMINUM ISOPROPOXIDE AND ISOPROPYL ALCOHOL INTO A REACTION VESSEL, SAID ALUMINUM ISOPROPOXIDE CONSTITUTING ABOUT 87 TO 95% BY WEIGHT OF THE TOTAL WEIGHT OF ALUMINUM ISOPROPOXIDE AND ISOPROPYL ALCOHOL, (B) MIXING SAID ALUMINUM, ALUMINUM ISOPROPOXIDE AND ISOPROPYL ALCOHOL TO FORM A MIXTURE, AND (C) SIMULTANEOUSLY HEATING THE MIXTURE TO A TEMPERATURE OF ABOUT 88 TO 150*C. TO INITIATE THE REACTION BETWEEN ISOPROPYL ALCOHOL AND ALUMINUM.
