[PDF] diphenyl oxalate and hydrogen peroxide

Diphenyl oxalate (trademark name Cyalume) is a solid whose oxidation products are responsible for the chemiluminescence in a glowstick. This chemical is the double ester of phenol with oxalic acid. Upon reaction with hydrogen peroxide, 1,2-dioxetanedione is formed, along with release of the two phenols.

  • What does diphenyl oxalate do to a glow stick?

    The diphenyl oxalate is oxidised by the hydrogen peroxide, which, amongst other products, produces the unstable compound 1,2-dioxetanedione.
    This compound is so unstable that it readily decomposes into carbon dioxide, also releasing energy as it does so.14 oct. 2014

  • What chemicals are used to make glow sticks?

    Most are made of an outer plastic casing with a small glass capsule inside.
    The outer tube is filled with dye, which determines the color of the glow stick, and a chemical called diphenyl oxalate.
    The glass within contains hydrogen peroxide, the same thing you might use to clean out a cut or scrape.

  • Does oxalic acid neutralize hydrogen peroxide?

    As a Hydrogen Peroxide chemist, I can suggest there are many reducing agents that will react to "neutralize" Hydrogen Peroxide (including Sodium Sulfite, Sodium Thiosulfate, and Oxalic Acid).

  • Does oxalic acid neutralize hydrogen peroxide?

    Diphenyl oxalate (trademark name Cyalume) is a liquid ester whose oxidation products are responsible for the chemiluminescence in a glowstick.
    It can be synthesized by fully esterifying phenol with oxalic acid.
