Welcoem to posts!!
in the future - u will be able to do some more stuff here,,,!! like pat catgirl- i mean um yeah... for now u can only see others's posts :c
To clarify my plan is to use 100 grams of the KI to do a video on making anhydrous iodine. The other 100 grams is for a video on the best HI prep Ive found to date. I am still working on the selenium tetrabromide and oxybromide. I need to get some new rubber tubing because all the stuff that I had before is hopelessly contaminated with some kind of dark mystery substance.

Ordered 200 grams of KI to make I2 and HI.

Back in business. Got a USB rechargable one this time.

Is it appropriate to use solvents that arent chromatography grade for GC-FID analyses?

If chloral (trichloroacetaldehyde) and bromal (tribromoacetaldehyde) can both react with water to form a sedative hydrate (chloral and bromal hydrates which are prodrugs for 2,2,2-trichloroethanol and 2,2,2-tribromoethanol, respectively) then would iodal (triiodoacetaldehyde) also react with water to form a sedative drug? I know iodal hydrate is indeed a thing but I can find no mention of 2,2,2-triiodoethanol in the literature at all. Does this compound even exist and if so is it a sedative drug as well?
PS Fun Fact: Chloral hydrate is a CIV drug in the US (not sure about bromal hydrate) but the trihaloethanols which are the actual physiologically active compounds dont appear to be controlled substances (at least not that I can find). If course if the hydrate is formed even as a transient intermediate in the prep of the trihaloethanol then that is very much a crime. But if avoided it may be legal.

Todays haul of bromine from ~1.23 pounds of sodium bromide. This is about 190mL of Br2 which should be over 0.5 kilo of sulfuric acid dried bromine. One of these will become HBr and the other is my new stash of bromine. I still have about another pound of sodium bromide left to make more. I don't know why more people don't work with this stuff. It's one of the most useful oxidizers you can have in your collection and it's so easy to make.

Bromine a few degrees above its freezing point has a weird tendency to sticl to glass. It can be rinsed off and recovered with room temperature water.

Synthesis of bromine by reactive distillation. Got a nose full of chlorine gas a few times remembering how to set this up. That was fun.

I came home from work early today (been sick the last few days) and found this waiting for me when I got here. There's nothing like half a liter of THF waiting on you to make you feel a little better. I've got to make bromine first and I'd like to make some hydrobromic acid. I might do videos on those. I know I've done them before but it might still be fun. But I'm not done with the selenium tetrabromide/chloride. It also occurred to me that I've never done an iodine complex of selenium before. The compounds are generally black and not really anything special to look at but I don't think anyone else has done one. As for the THF I have a few things in mind for it. You won't be disappointed. Stay tuned!!
PS With my current work schedule the best I can hope to accomplish is one video a week. I might be able to get out too if it's a week where there's a holiday and I have some days off. But my goal from here on out is to get one out every week (knock on wood!!).
