WebBig Chemical Encyclopedia. Peroxyoxalate. The chemical activation of a fluorescer by the reactions of hydrogen peroxide, a catalyst, and an oxalate ester has been the object of several mechanism studies. It was first proposed in 1967 that peroxyoxalate (26) was converted to dioxetanedione (27), a highly unstable intermediate which served as the ... WebThe Science Behind Glow Sticks. Glow sticks contain two sets of chemicals that when combined, create a chemical reaction called Chemiluminescence. In the outer part of the glow stick, a combination of phenyl oxalate ester and fluorescent dye are used. Inside the glass tube, a combination of hydrogen peroxide and a phthalate ester solvent are mixed.
