Question

Based on the information given, what would be the best “recipe” to make a glow stick?

Introduction Most people are probably familiar with the commercially available light sticks that glow a bright green color when the plastic stick is bent slightly. Most people, on the other hand, have little or no idea about the chemistry behind this "eerie bright green glow." In its simplest terms, the chemistry involves energy transfer from one substance to another. This glowstick reaction exhibits chemiluminescence - a process when light is emitted from a chemical reaction. Glow sticks are composed of three main components: (a) an oxalate ester; (b) hydrogen peroxide; and (c) a dye. Unfortunately, commercial glowsticks utilize oxalates which generate products in the chemiluminescent reactions that are environmental toxins. A better approach is to utilize chemicals which pose little or no threat to the environment. Such an approach invokes one of the principles of green chemistry. Green chemistry (or sustainable chemistry) is the design, development, and implementation of chemical products and processes to reduce or eliminate the use and generation of substances hazardous to human health and the environment. A total of twelve principles of green chemistry have been outlined and can be found on the webpage of the Green Chemistry Institute of the American Chemical Society (ACS).2 The process of making organic compounds is known as organic synthesis. Most pharmaceutical drugs used today are made by synthetic organic chemists in the laboratories of pharmaceutical companies. In this experiment, you vwill synthesize, isolate, and characterize divanillyl oxalate (D "greener" alternative to commercial oxalates. This is a greener oxalate since the product of the chemiluminescent reaction using DVO is simply vanillin - the primary component of the extract of the vanilla bean. The synthetic reaction you will erform in this experiment to form DVO is shown below: VO), a HO vanillin Divanillyl oxalate Triethylamine Cl CI Cl oxalyl chloride Triethylammonium chloride 70

Explanation / Answer

The DVO prepared in this experiment is a good source of oxalate diester. Which upon degradation produces oxcalic acid and Vanilline which are environmental friendly chemical or they are not toxic to the environment. Hence best combination to make Glow stick is :

DVO + H2O2 + some environment friendly dye.

Preparation of DVO also uses Green chemistry principles such as High atom economy, less use of solvents.
