chemicals in glow sticks
While diphenyl oxalate is generally considered safe for use in glow sticks and other consumer products, it can be toxic if exposure occurs in large amounts.
Is cracking a glow stick a chemical reaction?
[continued on back] When a glow stick is bent or cracked, it will begin to glow.
A chemical reaction occurs.
During a chemical change, two chemicals react with each other to form a brand-new chemical.
The glow stick has two substances— one inside the plastic case, the other inside a glass tube within the plastic case.
What is the chemical reaction that glows?
The chemiluminescent reaction is initiated by the oxidation of the oxalate ester in the presence of hydrogen peroxide and catalysed by a base such as sodium acetate.
The initial oxidation product is 1,2-dioxetanedione, which rapidly decomposes to electronically excited carbon dioxide.16 avr. 2019
Are the chemicals in glow sticks bad for the environment?
Once the luminescence of the product fades away, the consumers will discard it, after which it enters the last phase of its life cycle–waste disposal.
Glow sticks do not have a recycle phase in their life cycle, as the chemicals inside of the plastic tube are toxic, so they are sent directly to landfills upon disposal.
