Warning: This experiments requires the handling of dangerous and volatile chemicals. It must only be carried out in a fumehood or outdoors.
All chemicals must be disposed of properly. Everything will be contaminated with mercury/mercury salts. NOTHING CAN GO DOWN THE DRAIN OR IN THE GARBAGE. Only carry out this experiment if you can dispose of the chemicals and combustion products properly.
Every step of this synthesis deals with dangerous or toxic materials. Gloves, safety glasses and a lab coat are mandatory.
Here is a video to show you how volatile elemental mercury is. It lets off a lot of vapor and breathing this must be avoided.

Fuming nitric acid is defined as having a concentration of HNO3 greater than 86%. This is much higher than the conventional 68% of common lab nitric acid.
The reaction between the nitric acid and the nitrile and latex gloves is extremely exothermic and violent. It is often recommended to avoid using gloves altogether when working with fuming nitric acid unless resistant gloves are available (e.g. butyl rubber gloves).
Regular concentrated nitric acid is still not good to use with latex gloves. Latex offers little to no protection. Nitric acid can quickly penetrate the glove and then irritate skin.
Fuming nitric acid is not nearly as common and it is used in much fewer reactions. For example, for the synthesis of high explosives. The high concentration of HNO3 is required in order to nitrate a molecule several times. For example, TNT, or tri-nitrotuluene, is prepared using fuming nitric acid. It is possible to di-nitrate it using concentrated nitric acid, but the third nitration is unlikely to occur, so yield will be zero or uselessly low.
Hello. This is the official, full-length (81 min) version of the 2005 documentary, McLibel. This film was made completely independently (no studio/broadcaster backing) over four long years.

Sick, twisted, politically incorrect and Freakin’ Sweet animated series featuring the adventures of the dysfunctional Griffin family. Bumbling Peter and long-suffering Lois have three kids. Stewie (a brilliant but sadistic baby bent on killing his mother and taking over the world), Meg (the oldest, and is the most unpopular girl in town) and Chris (the middle kid, he’s not very bright but has a passion for movies). The final member of the family is Brian – a talking dog and much more than a pet, he keeps Stewie in check whilst sipping Martinis and sorting through his own life issues.
Capsaicinoids are interesting compounds with multiple, very different uses.
In this video I use a Soxhlet extractor to extract the capsaicinoids from Ghost Chili peppers.

Ever since the American company Mondelez (Formerly Kraft) bought Cadbury in 2010, the classic brand has seen a steady decline
The classic British brand has suffered through changing recipes to resemble horrendous American chocolate, shrinkflation and bland advertising. Cadbury is now just another cog in a huge corporate machine, and a shell of its former self.

In this video, I will be synthesizing p-nitroaniline from acetanilide. This chemical is used mainly as a precursor for a dye, but it can also be used in an interesting reaction with sulfuric acid.
Note: My dehydration reaction did not work nearly as nicely as other videos. I just found however, a link explaining how the reaction should be carried out. Here is the link: http://firstyear.chem.usyd.edu.au/dem...
It suggests using much more sulfuric acid than I did and to stir the mixture.
