How to make TCPO or bis(2,4,6-trichlorophenyl) oxalate, used in glow stick reactions. WARNING: This procedure should only be performed by, or under the direct supervision of, an experienced chemist. Please refer to the material safety data sheets of all chemicals for their hazards. Synthesis must be performed in a fumehood. Full written procedure can be found at our website: sites.google.com The exact same process is used in glow sticks. This is NOT mountain dew. Mountain dew cannot glow like this, it does not have the crucial TCPO chemical or any chemical like that. The reaction will glow in the dark for several minutes if you use ethyl acetate as the solvent. It will glow for several hours if you use diethyl phthalate as the solvent. Thanks for watching! Please subscribe, rate and comment! All the chemicals used in this video were purchased from Alfa Aesar. www.alfa.com

Dr. Arnab Bhattacharya (TIFR) demonstrates the Traffic-lights and TCPO-Chemiluminescence reactions at The Fergusson College Chemistry Club, Pune. Traffic lights reaction : Pour about 150 mL of 0.1 M dextrose into a bottle. Add 6 mL of 3 M NaOH solution and 4-5 mL of indigo carmine solution. This should be done about 30 minutes before the demonstration is to be used. The color of the solution will gradually change and become yellow. When the solution is shaken gently it will turn back to green or a light blue. This cycle can be repeated many times. After a while the indicator seems to "wear out". When this happens add more indigo carmine to enhance the color changes. TCPO-Chemiluminescence : mix together - 10mL Diethyl Phthalate (solvent) 3mg of fluorescent dye (9,10-bis(phenylethynyl)anthracene for green, Rubrene for yellow, 9,10-diphenylanthracene for blue, and rhodamine B for red.) 50mg TCPO (Bis-2,4,6-(trichlorophenyl)oxalate) 100mg sodium acetate 3mL 30% hydrogen peroxide (add last to start reaction)

How to make a 100 ft glow stick. Brighter than Electroluminescent wire and self-powered. This can be used to decorate, glow stuff up, or create all kinds of awesome effects. Warning: TCPO is carcinogenic and you should wear gloves and masks while working with it. The procedure is simple, mix together 500mg of 9,10-bis(phenylethynyl)anthracene and 17g of TCPO in 500mL of diethyl phthalate solvent and heat it up until it dissolves. Then top it up to about 2.1 liters and add 120mL of hydrogen peroxide and 10g of sodium acetate. Shake thoroughly and draw into a 100 ft glow stick with an inner diameter of 3/8". Suction by a vacuum pump is recommended. To prevent spilling the ends should be capped with brass or plastic compression fittings. Leave 5+ feet of space in the tube to allow for expansion of the chemicals depending on temperature. Glow stick will last for about 6 hours. Use more TCPO if a longer glow is needed. Possibly the world's biggest glow stick.

We make a glow stick that changes colour with time. To do so, we prepare our standard chemiluminescent mixture: 10mL Diethyl Phthalate 3mg of 9,10-bis(phenylethynl)anthracene 5mg Rhodamine B 50mg TCPO 100mg sodium acetate 3mL 30% hydrogen peroxide (add last to start reaction) First the red Rhodamine B glows and masks the 9,10-bis(phenylethynl)anthracene. But since Rhodamine B is unstable it slowly breaks down and eventually the glow stick will turn green. The whole process takes about ten minutes.

We show how to make glow sticks and go through all the chemicals needed as well as how to make different colors. We also talk about the chemistry and scientifically research a proposed mechanism. To make the glow stick mix together the following: 10mL Diethyl Phthalate (solvent) 3mg of fluorescent dye (see below) 50mg TCPO (see below) 100mg sodium acetate 3mL 30% hydrogen peroxide (add last to start reaction) The fluorescent dye can be 9,10-bis(phenylethynyl)anthracene for green, Rubrene for yellow, 9,10-diphenylanthracene for blue, and rhodamine B for red. TCPO is expensive to buy but can be made for much cheaper by following the directions in our previous video: www.youtube.com The chemicals, including the ones to make TCPO were purchased from alfa aesar: www.alfa.com The Rhodamine B and Rubrene dyes were instead purchased from sigma Aldrich www.sigmaaldrich.com The dyes and TCPO are carcinogenic and gloves should be worn when handling them. The TCPO and sodium acetate amounts can be varied considerably and still obtain good light. Smaller quantities tend to be dimmer and decay faster, while larger quantities last longer. For those of you higher level individuals that actually do want to know the mechanism for this process, please refer to this article: pubs.acs.org

A full two liters of glow fluid, about as much as you would find in 100 medium sized glow sticks. Imagine going to a rave and glowsticking with a couple of these! Not the world's biggest single glow stick, but still awesome. We made this using all the same chemicals in our previous glow stick making video just scaled up by a factor of 100.

It's very important to use dry diethylether and dry glassware otherwise low yields are observed. The phenyllithium is extremely reactive and pyrophoric so have fire extinguisher nearby, the diethylether is extrmeley flammable and volatile so no flames and sparks!! The reaction is pretty straightforward and easy to do if you have the chemicals and glassware and the luminescent reaction with TCPO is beautiful.

How to Make a Complete and Refillable Glow Stick with a steampunk style to it. The idea is simple, use compression fittings normally used in plumbing to create a glow stick tube that can be emptied and refilled when the fluid dies. The vials or ampoules of hydrogen peroxide is created from cheap glass pipettes that are flame sealed. The other chemicals can be found from our original glow stick reaction video: www.youtube.com An important change though is the use of diethyl phthalate solvent rather than ethyl acetate. Diethyl phthalate gives a longer lasting light. Other aliphatic dialkyl phthalates can be used including diethylhexyl phthalate so you can use whatever you have onhand. If built correctly and the purity of chemicals is good then it will last 3-8 hours. If you're having problems with leaking be sure to use teflon tape. Subscribe, rate and comment! Special note: Brass is pretty hard, so if you glowstring with this and hit someone... it's going to HURT... so be careful! Our website at: www.nurdrage.com

Trials are conducted with excess amounts of an individual reactants. Trial I: Control Trial II: Excess TCPO Trial III: Excess R6G Trial IV: Excess Sodium Acetate Trial V: Excess Ethyl Acetate Trial VI: Excess Hydrogen Peroxide (In this trial I accidentally forgot to add the Sodium Acetate. The reaction started with a long lasting orange glow; then became a very quick and very bright glow after I added the Sodium Acetate)
