Synthesize it Brendan Ha and Marvin Dang performing for Chem 14D. Quality is extremely low tech, but we had to do with whatever was at hand. Let's hope that this performance lands us a perfect extra credit score! Shout-out to Prof. Garg for a wonderful class!! Yeah man, this ya boy Mistah Ha mayn The ochem ninja man Marvin D, the real king of chem mayn Now don't act like ya'll don't know what we're doing man Let me give you a 101 on how to synthesize Look Prof. Garg know what this is Synthesizing molecules up and down the strip You an alkene bond you can react Hit the electrophile with a nucleophilic attack Now what if i want a hydrogenation Need a catalyst to complete the creation From the same side its a syn addition Carbon to carbon in case you're not listening Hydrogen Halides React sort of the same With stereo, markovnikov is the name Can't get an A in this class, had to make a video Addition of halogens got no regio What you know about it, getting it wet Buy some BH3 and you're reaction is set Anti-mark the H, except for oxymercuration Throw in some NaBH4 to complete the reduction When you wanna do good And you're feeling real hood What you gon' do? Synthesize it! Synthesize real quick! Diels-alder reaction, all in one motion Makes an alkene while the reaction's still rollin' Bonding, shifting, cyclohexening Hit the streets, cuz Steven be leaning With a benzene ring it might be too stable With EAS the reaction is more able Sulfunation, Nitration both need sulfuric acid Both ...

Preparation of Nitric Acid 90% nitric acid containing barely any nitrogen oxides is prepared in high yield by distilling a mixture of ammonium nitrate and drain cleaner grade sulfuric acid under vacuum. Nitric acid density information is available at this link: Special thanks to Ozonenerd of Reactionfactory for pointers on this preparation. The intro music clip is from "Stealing Fat" by The Dust Brothers. I believe this falls under fair use.

Deflagrating picric acid (TNP) This is a small bit of TNP which was put in the tin casing around the tea candles.. It was heated, and spontaneously ignited. For those new to this, picric acid is trinitrophenol (from the nitration of phenol, I used the asprin method). The acronym TNP comes from the chemical formula TriNitroPhenol, the same way TNT gets it's name.

Nitrocellulose watje deflagratie Deflagratie van een klein watje nitrocellulose. Watten(cellulose) genitreerd met een mengsel van kaliumnitraat en zwavelzuur. Deflagration of a little piece of nitrocellulose. The nitration mixture was 25 grams of potassium nitrate and 30 ml of sulphuric acid. Very slowly add the potassium nitrate to the acid and stir toroughly. Don't breath in the NOx vapors(!). When the potassium nitrate has disolved, add your cellulose and let it sit for about 20 minutes. Then wash the cellulose very good and neutralize with a solution of sodium bicarbonate. Then wash again and let it dry. Now is your stuff ready. ps. You maybe want to do this outside, because the vapors are not much fun to breath in! (highly toxic!)

Cap sensitive ANFO (1.15kg) The "ANSUN" is a mixture of activated ammonium nitrate (94.5%), sunflower oil (5.5%) and manganese dioxide (+2%), prepared by the method of nitro-genes (see ). It was initiated with a detonator comprising 2g of guanylazide picrate, 0.2g MHN, 0.05g Na***. Underneath lay a charge of ammoniumnitrate (94%) and a mixture of mono- and dinitroxylene (6%), made from the nitration of para-xylene with nitrate/sulfuric acid. I stored it for more than a year and it seemed to have captured some moisture over time, but detonation was no problem with half a kilo of ANSUN around :). I apologize for the ***ty quality and for shutting off the camera too early; this was due to sudden panic induced by the ferocity of the explosion. But the most important is that it actually worked to make a cap sensitive ANFO (without giving up on power).
Nitric Acid Synthesis Nitric Acid is produced from 15 molar sulfuric acid and sodium nitrate. Warning: Nitric Acid is extremely dangerous. Only attempt if you have extensive experience in chemistry. Side note: the yellowish nitric acid can be purified by vacuum distillation.

Will Holme : editor and did the acylation stop motion, adam taleb-bendiab, john findley and tom balmer, i hope you enjoy it and i also hope you get something out of it :)video editing done on sony vegas :) ps. please subscribe and comment, and yes, it is a true story
Testing out my batch of Nitrocellulose!!! Burning Nitrocellulose is always fun as it basically makes the ball of cotton evaporate out of thin air! It amused my grandmother and my aunt. Notice how I didn't even need to put a flame on it. It is extremely flammable and a blown out match head is enough to ignite it! Nitrocellulose is a common ingredient in gunpowder today as it leaves no residue to clog up the barrels. It takes a very little amount. Burning a lot is not nearly as interesting so do little ones at a time! This was really exciting for me to make, as it was my very first material I nitrated! I made a solution of 25mL of 98% Concentrated Sulfuric Acid with 25mL of 70% Concentrated Fuming Nitric Acid and let it sit before cooling down. Then i put 5 cotton balls in a acid-safe plastic container and saturated them with the acidic solution. I let it sit for 5 minutes stirring occasionally. Then I placed the cotton balls in a sodium bicarbonate water solution and let it neutralize until there was no fizzing. Using my vinyl gloves I was able to squeeze the cotton balls in the solution until it stopped fizzing. I then rinsed the cotton balls in another container of clean water TWICE! You must remove the remaining sodium bicarbonate in the cotton balls otherwise it burns it which slows the reaction. Then I drained them and puffed them out as much as I could and let them dry for 3 hours in my room right next to a fan.

The Home Scientist 017 - Synthesize Nitrocellulose (Guncotton) Dr. Paul Jones synthesizes nitrocellulose from cotton balls and a mixture of concentrated sulfuric and nitric acids. In the video, we talk about nitrating for 2 minutes, but as you'll see watching the video, we actually nitrated different cotton balls for different times, with a minimum of two minutes and maximum of about 4 or 5 minutes. Those nitrated for 4 or 5 minutes were considerably more energetic and faster burning than those nitrated for only two minutes, so if you reproduce this experiment you may wish to nitrate the cotton balls for 4 or 5 minutes and then drench them by dumping them all at once into a large container of water for the first rinse rather than following the procedure Paul used in the video. Be extremely careful with this procedure. The concentrated acids are extremely corrosive. The nitration process itself produces *extremely toxic* nitrogen oxides (visible as the organish vapors in the video), so do this outside or under an exhaust hood, particularly if you scale up the experiment. The nitrocellulose product is extremely flammable, and if highly nitrated may detonate rather than simply burning. If you live near a city or large town, you may be able to purchase concentrated nitric acid locally. If not, is one good source. They sell one pint (473 mL) bottles of 70% ACS reagent grade nitric acid for $9.99. There's a $20 hazardous shipping surcharge, but IIRC you can order up to 8 bottles for one surcharge.
Nitrocellulose Preparation and Deflagration Tests Cellulose hexanitrate (which we're almost certain we ended up with) is easy to make and spectacular to demonstrate. Please see previous video on the preparation of nitric acid and please heed all safety warnings present in the video; it's for your own good, y'know. If you have a better way to squeeze the nitrating mixture out of the freshly-nitrated cellulose, please share! Reactions seen here (Because we do not know the degree of nitration with certainty, the first pair of reactions is for cellulose hexanitrate, which Ozonenerd is not as sure as ViggenGuy about our having made, and the second pair is for cellulose trinitrate.): 2*C6H10O5 (s) + 6*HNO3 (aq) → C12H14N6O22 (s) + 6*H2O (l) catalyzed by H2SO4 (aq) 2*C12H14N6O22 (s) + 9*O2 (g) → 6*N2 (g) + 24*CO2 (g) + 14*H2O (g) 2*C6H10O5 (s) + 3*HNO3 (aq) → C12H17N3O18 (s) + 3*H2O (l) catalyzed by H2SO4 (aq) 4*C12H17N3O18 (s) + 29*O2 (g) → 6*N2 (g) + 48*CO2 (g) + 34*H2O (g)
