Claim 1
Independent Claim
105 words
THE PROCESS OF PREPARING WATER SOLUBE COMPLEXES OF ALUMINA FROM SODIUM ALUMINATE WHICH COMPRISES CONTAINS FROM 7% TO 35% BY WEIGHT, BASED ON THE WEIGHT OF THE SODIUM ALUMINATE, OF A WATER SOLUBLE, ORGANIC POLYHYDROXY STABILIZING COMPOUND, OF NOT MORE THAN 7 CARBON ATOMS WITH A WATER SOLUBLE, LOWER ACYCLIC CARBOXYLIC ACID OF NOT MORE THAN 6 CARBON ATOMS IN CHAIN LENGTHS IN AN AMOUNT SUFFICIENT TO NEUTRALIZE THE SODIUM PRESENT AND TO ADJUST THE PH TO NOT MORE THAN 10, AND THEN HEATING THE REACTANTS TO A TEMPERATURE OF BETWEEN 100*F. AND 200*F. FOR A PERIOD OF TIME SUFFICIENT TO PRODUCE A CLEAR SOLUTION.
