Warning: Ether is extremely flammable. This must only be carried out in an extremely well ventilated area.
In this video we make diethyl ether from ethanol and sulfuric acid. I adapted by procedure from youtube user myst32YT. Here is a link to his ether synthesis video: https://www.youtube.com/watch?v=ytdO3YzXNkQ
The final product likely still has a little bit of a water in it. I would suggest adding more drying agent or molecular sieves if you need it to be anhydrous. ... https://www.youtube.com/watch?v=6Z2oE8-uthU
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/demonstrations/files/10.12.pdf
It suggests using much more sulfuric acid than I did and to stir the mixture.

Apparently I made my $250 Patreon goal... I guess I have to commit for 6 months now?
Hey guys, today we make a little copper hydroxide for the purpose of making some Schweizer's Reagent to dissolve cotton!
That will be posted in a future video and it is actually a revisit of an old video.

In this video, we will be making lithium hydroxide by reacting lithium metal with water!
I plan to use the lithium hydroxide to make some lithium based drugs (used to treat bipolar disorder) and to make lithium peroxide (reacts with CO2 and produces O2)
I plan to do an Q and A video, so if you have any questions you'd like me to address in the video, leave them in the comments.

For this video, I am going to be making some laughing gas, aka nitrous oxide. Then, I'll be using it to carry out the classic Barking Dog experiment.
To make it, I'll be using the safer method, which uses sodium nitrite and hydroxylamine hydrochloride. The typical industrial process, using ammonium nitrate, can be quite dangerous.
This video has been a long time coming and I am glad that I could finally release it. I have been promising people this forever!

Today we are making some cadaverine from lysine. The yield is kind of crappy, but it is still nice and stinky :)

Warning: This experiment deals with dangerous and toxic chemicals.
(Copied from the other nitric acid video)
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 or Ansell brand laminated film gloves which were suggested by user Atomosphysica). 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.

Acetylsalicylic is readily available in Aspirin tablets. Chemically, it is a useful molecule. It can be converted to salicylic acid and then phenol, which is an extremely useful precursor. Also, the salicylic acid itself can be used to make the minty smelling wintergreen.
All in all, acetylsalicylic acid is a quite desirable chemical. However, before it can be used in any reaction, it must first be separated from the Aspirin pills, which contains binders and fillers. In this video, I will outline one method of separating the acetylsalicylic acid (also referred to as ASA) from pills.
The final yield of ASA from 500 325mg tablets was 152g (or about 94%).

In part 1, I will be doing the classic Bakelite demonstration and making resole.
