3A molecular sieves are the way to go dehydrating ethanol. Not very fast but really cheap considering they can be regenerated hundreds or thousands of
times.

Distilled water is pricey? last time I checked it was like 70 cents a gallon
Not sure if it was mentioned yet but benzaldehyde it hard to come by (depending on where you live) yet there is like 5000000 different ways of making
it and a lot are quite easy.

Lactic acid? We make it just by running, but it's stupidly expensive. Also, pyruvic acid. Not sure why those two are so expensive, since they can be
made without much difficulty via the oxidation of propylene glycol.

Lol. How might you extract the lactic acid produced in the body?

Compounds in milk
And extracting this is not my video
He extracts compounds from milk including lactose
https://m.youtube.com/watch?v=BV8aFRII1M4
Also
Racemic lactic acid is produced in industry by addition of hydrogen cyanide to acetaldehyde and subsequent hydrolysis of forming lactonitrile.
Hydrolysis performed by hydrochloric acid and ammonium chloride forms as a by-product of lactic acid. Excerpt wikipedia lactic acid

If you kept reading, you might have noticed that only one company in Japan still makes it this way, and others all start with cheaper precursors like
glycerol and propylene. However, lactic acid is a chiral molecule, which could make it harder to synthesize. And I doubt there's that much demand for
it either.

ive seen styrene sold towards 100 dollars for half a litre, metal plastic or something, stabilized with 1% methanol, supposedly polymerizes into
polystyrene when left out in air
this stuff can be made from pyrolysis of polystyrene, which can then be oxidized into benzaldehyde
one could go about making formate salts by tossing carbon monoxide, possibly from NaHCO3 electrolysis cell through calcium hydroxide, it then forms
calcium formate
some very hefty solvents springs to mind, SCl2
one guy claimed to having been able to run a very neat manufacturing of oleum, 185% H2SO4, using sulfur, air and a catalyst, as well as drying agent
for air (again sulfuric acid), cant remember what oleum cost last time i even had a chance to see price of such, but extremely expensive
colloidal silver through silver oxalate decomposition controlled in water and / or glycol mixture
guanidine carbonate! or well guanidine salts in general, recall AN and UNitrate heated together for some hours would create a bunch of guanidine
nitrate
chloroacetates, simply chlorination of acetic acid
cyanides
acetaldehyde, mostly because its pretty difficult to get around? a bonus is that one can combine different things with the reaction vessel that then
further reacts with aldehydes, amines and what not
chromate and dichromate from stainless steel - HCl + Me(tal) = MeClx -> MeClx + NaHCO3 = MeCO3/OHx -> Cr(OH)3 + NaClO = NaCrO4 -> NaCrO4 +
HCl = Na2Cr2O7, excess HCl forms chlorochromate which has some potential use as oxidizer for organics, also serves as a neat little continous chlorine
generator for whenever you feel like pouring out a bit of chlorine on burning steel wool or what not
oxalic acid from sugar and nitric acid
nitric acid
methanol distilled from wood
got a hint laying about saying butyl alcohol oxidation turns into methyl ethyl ketone?
"ketene lamp" (sort of build technical of what i understand, you want high temperature, high resistance kiln wire, can produce acetic anhydride i
think?)
piperine, but very high risk reaction using sodium metal, cant recall procedure but its quite expensive stuff
ethyl chloride from Cl2 + ethanol
phenol from decomposition of salicylic acid, it can be tossed a bit back and forth in aromatic solvents with some patience
fine zinc metal powder from sodium zincate electrolysis
oxalic acid and glycol forming allyl alcohol (was it allyl?)
bunch of these things are either watched or barely possible to buy, others i wrote down simply for how useful they are

Hey, I don't think iodine should be in the list up there. You can buy 10 grams for 20-40 dollars on ebay, but making some from tincture (are there
other sources?) costs 10-15 dollars a bottle, and has about 1-2 grams.

Chromate and dichromate from stainless steel is not particularly cost effective. Assuming 100% yield, I can actually buy chromates for slightly
cheaper than I can make them, and when I make them, the yields aren't 100%. Of course, there is an extremely wide range of prices for [di]chromates...
they are typically sold to chemists at exorbitant prices. But they are also used extensively for industrial purposes, so if you shop around, you can
find technical grades at low cost. That's good enough for almost all purposes. And of course, you can also purify them yourself if you want some
expensive grade stuff....

How about benzene? Nigh impossible to get outside of chemical suppliers, but easy enough to make from benzoic acid if you have the patience.

LOL! 100 bucks for a kg (!) os KI or NaI + drugstore H2O2 + hardware store HCl = All the I2 you want.

100 bucks for a kg of potassium iodide? Pass, i'll buy some pure iodine on ebay. Besides, who needs a kilogram?

There's probably no easier chemical than iodine to purify.

@altking: that's where desiccants are your friend. You just need to find one that's inert to ethanol but sucks up any water that comes near it. You
tend to need to leave it overnight though. I've heard that potassium carbonate works well for this, but that's kind of expensive and reacts easily
with anything acidic. Silica gel would probably be a good bet though.

Extracting Sodium needs at least molten sodium hydroxide! (which is obtained at temp above 400°C) or molten NaCl (above 800°C). Na & K can not
easily be obtained.
I still don't have acces to any bromide compunds, so i'm planning to extract it from sea water later.

Only half true. Yes, sodium is pretty difficult to prepare in a home setting.
Potassium on the other hand, is much more easily prepared via this:

I made sodium metal once. I used sodium hydroxide and magnesium powder and lit the magnesium. After that I added the mess to a beaker with water and a
layer of mineral oil over the water. The sodium stayed in the oil mixture as the magnesium hydroxide sank to the bottom.
It was kinda easy, but then I melted the sodium into a nice blob.

Lol found this funny - perhaps because I use the same tone to correct people about chemistry in general...
I can't recall if Chromyl Chloride was up there, or Dioxane, but doug's lab makes those synths look pretty easy. Not that either are exra-ordinarily
useful.

There are safer reagents for this purpose, but chromyl chloride can be used to oxidize primary alcohols to aldehydes. It's rather dangerous stuff, but
at least the boiling point isn't terribly low.
Dioxane actually looks tremendously useful... I'm not sure why it isn't more popular.

Carcinogenic, low yield when synthesizing from ethylene glycol and sulfuric acid, difficult to dry and purify, forms peroxides on storage...

I've already seen at least one video about this method, but i just forgot to mention it. Anyway, i don't have any Mg powder so it's somehow difficult
to make it since i only have MgCl2 & MgSO4
