Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
In the process for the synthesis of mordenite from a forming solution containing a mixture of alumina, silica, alkali metal oxide and water, the improvement which comprises adding a metal complex selected from the group consisting of cobalt phthalocyanine; (o-phenanthroline) 3 FeClO 4 ; Ru(bipyridyl) 3 Cl 2 and Ni(bipyridyl) 3 ClO 4 to the reaction mixture and maintaining the same at a temperature of from 100° F. to about 400° F. until crystals of mordenite are formed with the proviso that when cobalt phthalocyanine is used the OH - /SiO 2 ratio of the forming solution is 0.6.
Claim 2
