diphenyl oxalate and hydrogen peroxide
Diphenyl oxalate is commonly used in the production of glow sticks, which are novelty items that emit colorful light.
The chemical reaction between diphenyl oxalate and hydrogen peroxide produces energy that excites a fluorescent dye, causing it to emit light.
How do you make diphenyl oxalate?
The process for synthesizing diphenyl oxalate involves heating a mixture of oxalic acid, phenol, and sulfuric acid in a solvent.
What happens when hydrogen peroxide reacts with phenyl oxalate ester?
Glow sticks light up when oxalate esters react with hydrogen peroxide to form a high-energy intermediate (possibly 1,2-dioxetanedione).
This intermediate reacts with dye, which moves to an excited state (indicated with *) and then releases light as it relaxes.19 oct. 2021
What chemicals react with hydrogen peroxide?
Hydrogen peroxide can be derivatised to form compounds capable of acting as a source of active oxygen by reacting with many compounds such as borates, pyrophosphates, carbonates, sulphates, silicates and organic compounds such as carboxylates and amides.
