Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
44 words
A method of preventing contamination or decontaminating articles or structures in need of such treatment which comprises treating said articles or structures with a decontaminating or prevention of contamination effective amount of a catalyst which binds atmospheric oxygen and converts it to a superoxide.
Claim 2
Independent Claim
44 words
A method of preventing contamination or decontaminating articles or structures in need of such treatment which comprises treating said articles or structures with a decontaminating or prevention of contamination effective amount of a catalyst which binds atmospheric oxygen and converts it to a superoxide.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein the catalyst is a transition metal complex of a phthalocyanine.
Claim 4
Dependent Claim
12 words
The method of claim 1 wherein the catalyst is Co(II) tetrasulfonated phthalocyanine.
Claim 5
Dependent Claim
12 words
The method of claim 1 wherein the catalyst is Co(II) tetraamino phthalocyanine.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein said articles or structures are treated by coating them with a paint containing an effective amount of said catalyst.
Claim 7
Dependent Claim
12 words
The method of claim 5 wherein the catalyst is Co(II) tetrasulfonated phthalocyanine.
Claim 8
Dependent Claim
12 words
The method of claim 5 wherein the catalyst is Co(II) tetraamino phthalocyanine.
Claim 9
Dependent Claim
28 words
The method of claim 1 wherein the article or structure fabric and the treatment is dyeing the fabric with a dye composition containing an effective amount of catalyst.
Claim 10
Dependent Claim
12 words
The method of claim 8 wherein the catalyst is Co(II) tetraamino phthalocyanine.
Claim 11
Dependent Claim
12 words
The method of claim 8 wherein the catalyst is Co(II) tetrasulfonated phthalocyanine.
Claim 12
Dependent Claim
21 words
A decontaminating composition for dehydrochlorinating mustard gas comprising an effective decontamination amount of an atmospheric oxygen binding catalyst and a carrier.
Claim 13
Dependent Claim
21 words
A decontaminating composition for dehydrochlorinating mustard gas comprising an effective decontamination amount of an atmospheric oxygen binding catalyst and a carrier.
Claim 14
Dependent Claim
19 words

Claim 15
Dependent Claim
19 words
A composition of claim 11 wherein the carrier is a paint composition and the catalyst is Co(II) tetraamino phthalocyanine.
Claim 16
Dependent Claim
20 words
A composition of claim 11 wherein the carrier is a polymer film former and the catalyst is Co(II) tetrasulfonated phthalocyanine.
Claim 17
Dependent Claim
20 words
A composition of claim 11 wherein the carrier is a polymer film former and the catalyst is Co(II) tetraamino phthalocyanine.
Claim 18
Dependent Claim
19 words
A composition of claim 11 wherein the carrier is a fabric dye and the catalyst is Co(II) tetrasulfonated phthalocyanine.
Claim 19
Dependent Claim
19 words
A composition of claim 11 wherein the carrier is a fabric dye and the catalyst is Co(II) tetraamino phthalocyanine.
Claim 20
Dependent Claim
26 words
A method of making an article or structure self-decontaminating which comprises coating said article or structure with an effective amount of the composition of claim 12.
