Sublimated phthalimide in a large test tube, thought it was neat ![:)](./images/smilies/smile.gif)

That is 50gr of Iodoform.
I sell it to my friend (dentist) and he use it as disinfectant

We just ran out of deuterated solvents for NMR, so we had to make some. Here is a "few" ampules of mixed deuterochloroform/deuteromethanol with a
little added tetramethylsilane for NMR spectroscopy.

The iodoform is really cool looking. It reminds me of lead iodide which I just made. I have so many beautiful compounds and elements. I wish I had a
camera.

I *think* that on the left is triethylamine, then sulfur trioxide (something..) complex and dimethyl sulfoxide. Might be wrong but I wanted to take a
guess lol. I wish my job was like that ![:(](./images/smilies/sad.gif)
(Edit: is the one in the middle sulfur trioxide-pyridine complex?)

Yep, mailinmypocket got it. I was doing a Parikh-Doering oxidation (non-cryogenic version of Swern, ideal for scale up). Input material was 1.4kg
alcohol substrate in each flask (the upper picture shows the workup of the reaction, which took 3 days in total). These pics were taken a few months
back, but that was 2 batches of 12 required for the custom manufacture campaign. Unfortunately the smell ofdimethyl sulfide byproduct progresses
throughout the next three manufacturing steps.
They're 20L rbfs btw ;p Also note how we don't shake the sep funnels at that scale. They remain stationary... The phases are mixed in the reaction
pot, transferred to the funnel by vacuum line and separated. Organic gets sucked/poured back into the pot and washed with the next solution.
Just another picture to keep people happy... Again in a 20L pot, equipped with a 2L addition funnel full of acid chloride solution. It feels quite
funny looking at these pictures now because I'm currently working on microscale reactions.

Some nice crystals which formed at the bottom a flask.
It was a polymethoxy furane deriative what formed as a side product of a reaction, but it will be really useful for me in the future.

To satisfy large demands from the Vatican I decided to make isopropyl nitrite ![:D](./images/smilies/biggrin.gif)
![Isopropyl nitrite.jpg - 63kB](https://www.sciencemadness.org/whisper/files.php?pid=305447&aid=27110)
the bottom layer is really cool it looks alive and rippling
Shortly after this my stirring failed due to the Na2SO4 slush
I am really preparing this in preparation to distilling HCN as an antidote, just in case...

Yeah...I did the exact same reaction like a week ago. Modified orgsyn prep? Mine also failed when my stirring choked on sulfate. They are not kidding
about mechanical stirring. I had 3/5 of the sulfuric/alcohol in at that point too. I still scraped 1/2 of the supposed yield of ester though so it
wasnt a total wash.
I'm gonna nitrosate some cyclohexanone with it.

It was not my reaction, but: something crystallized from the mother liquor of an aromatic alkyl imidate and it looked great, just like on the
pictures. Organic crystals are awesome!

This was an attempt to grow crystals of copper(II) anthranilate by allowing methyl anthranilate to hydrolyse slowly in a solution of copper(II)
acetate in 50% aqueous acetic acid. They look more like copper(II) acetate to me, and seem to be somewhat soluble (which copper(II) anthranilate
isn't). So I'll chalk that up as a failure, along with the attempt to hook the microscope up to the computer so that I could get a picture without
resorting to an iPhone.
