Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
68 words
In a process for manufacturing synthetic mordenite, which process comprises hydrothermally treating an aqueous, inorganic mordenite forming solution that contains a source of SiO 2 whereby forming substantially pure synthetic mordenite having a characteristic microscopic texture, the improvement which comprises adding to said forming solution an amount of substantially colorless organic basic nitrogen compound, said amount being effective to alter said microscopic texture of said substantially pure mordenite.
Claim 2
Dependent Claim
68 words
In a process for manufacturing synthetic mordenite, which process comprises hydrothermally treating an aqueous, inorganic mordenite forming solution that contains a source of SiO 2 whereby forming substantially pure synthetic mordenite having a characteristic microscopic texture, the improvement which comprises adding to said forming solution an amount of substantially colorless organic basic nitrogen compound, said amount being effective to alter said microscopic texture of said substantially pure mordenite.
Claim 3
Dependent Claim
46 words
The process claimed in claim 1 wherein said organic basic nitrogen compound has a pK a from about 7 to about 12, and said effective amount is from about 0.01 mol to about 0.50 mol per mol of said SiO 2 in the mordenite forming solution.
Claim 4
Dependent Claim
41 words
The process claimed in claim 1 wherein said organic basic nitrogen compound is a quaternary ammonium compound and said effective amount is from about 0.01 mol to about 0.50 mol per mol of said SiO 2 in the mordenite forming solution.
Claim 5
Dependent Claim
14 words
