Abstract
Abstract A method for providing a hydrogen peroxide reactive chemiluminescent system which operates efficiently as one unit. The method avoids the necessity for separately storing two reactive components. It comprises adding under oxygen free conditions an organic compound selected from the group consisting of anthrahydroquinone, 2-ethylanthrahydroquinone, 2tertiarybutylanthrahydroquinone, and benzoin to a solution of an oxalate ester, a fluorescer, and a catalyst, if one is required. Upon exposure of this solution to oxygen, light is emitted by a chemiluminescent reaction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
74 words
A METHOD FOR GENERATING LIGHT FROM CHEMICAL ENERGY WHICH COMPRISES: A. PREPARING A LIGHT-PRODUCING FORMULATION BY ADDING UNDER OXYGEN-FREE CONDITIONS AT AMBIENT TEMPERATURE AN ORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF ANTHRAHYDROQUINONE, 2-ETHYLANTHRAHYDROQUINONE, 2TERTIARYBUTYLANTHRAHYDROQUINONE AND 2-HYDROXY-2PHENYLACETOPJENONE TO AN OXALATE ESTER - FLUORESCER COMPONENT WHICH WILL REACT WIT HYDROGEN PEROXIDE TO GIVE LIGHT; AND B. EXPOSING SAID FORMULATION TO AIR WHEREBY LIGHT IS EMITTED HAVING A LIFE OF FROM 30 MINUTES TO 24 HOURS.

Claim 3
Dependent Claim
20 words
The method in accordance with claim 1 wherein additionally a trace quantity of sodium salicylate or tetrabutylammonium salicylate is added.
Claim 4
Dependent Claim
37 words
A light generating formulation comprising: a. an organic compound selected from the group consisting of anthrahydroquinone, 2-ethylanthrahydroquinone, 2-tertiarybutylanthrahydroquinone and 2-hydroxy-2-phenylacetophenone; and b. an oxalate ester - fluorescer component which will react with hydrogen peroxide to produce light.
Claim 5
Dependent Claim
37 words
A light generating formulation comprising: a. an organic compound selected from the group consisting of anthrahydroquinone, 2-ethylanthrahydroquinone, 2-tertiarybutylanthrahydroquinone and 2-hydroxy-2-phenylacetophenone; and b. an oxalate ester - fluorescer component which will react with hydrogen peroxide to produce light.
Claim 6
Dependent Claim
