Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
62 words
A stabilized separate component in a chemiluminescent light system consisting essentially of a solution in organic solvent of a hydroperoxide compound and a stabilizing amount of a phenolic antioxidant compound of the formula ##STR2## wherein each of R 1 and R 2 is tertiary alkyl having 4 to 12 carbon atoms and R 3 is alkyl having 1 to 12 carbon atoms.
Claim 2
Dependent Claim
62 words
A stabilized separate component in a chemiluminescent light system consisting essentially of a solution in organic solvent of a hydroperoxide compound and a stabilizing amount of a phenolic antioxidant compound of the formula ##STR2## wherein each of R 1 and R 2 is tertiary alkyl having 4 to 12 carbon atoms and R 3 is alkyl having 1 to 12 carbon atoms.
Claim 3
Dependent Claim
44 words
In a chemiluminescent light system comprising at least two separate components, a first component consisting of the stabilized component defined by claim 1, and a second component comprising a solution of a bis-ester of oxalic acid and an organic fluorescent compound and a solvent.
Claim 4
Dependent Claim
14 words
A stabilized composition defined by claim 1 wherein said hydroperoxide compound is hydrogen peroxide.
Claim 5
Dependent Claim
13 words
A stabilized composition defined by claim 1 wherein said phenolic antioxidant is 2,4,6-tri-t-butyl-phenol.
Claim 6
Dependent Claim
13 words
A stabilized composition defined by claim 3 wherein said phenolic antioxidant is 2,4,6-tri-t-butyl-phenol.
