Reaction skill tree

What is the most door opening chemical reactions, i.e., what were the first?

Palladium catalyzed crosscouplings like the Buchwald-Hartwig, the Sonogashira, the Heck and the Suzuki reaction.

C + O2 = CO2 + heat and light

Next is crystal growing & purification using crystallization?

N2 + 3 H2 + [Fe catalyst, 20 Mbar, 500 C] >> 2 NH3

Hmmm. I'm rather fond of
C6H12O6 + 6O2 = 6CO2 + 6H2O
It's enabled me to do all sorts of stuff.

Now I'm off for some breakfast.

Strictly speaking, light isn't a product of the reaction. It's not chemiluminescent. Instead, the light comes from blackbody radiation due to all the heat.

But in terms of a "skill tree" for reactions, this is a good one for the bottom.

Calcium acetate from eggshels and vinegar.

You can use it to make acetone, tofu and the flammable jelly :)

I agree with calcium acetate. Crush bulk eggshells in ball mill until they pass a 40 mesh screen. Set up ketene lamp with a blowtorch and nail polish remover. Use a tube to guide the ketene into GAA (the only inaccessible part of the project, everything else is otc). Add the formed Ac2O to distilled, de-ionized, and de-mineralized water until a ~5 percent concentration of aqueous acetic acid is reached. Dump crushed shells into acid solution, and boil to dryness!

2 CuO + C -> 2Cu + CO2 Started the bronze age.

How can one answer such an ambibuous question?

i think most of the answers are ironic because of the vagueness of the question. wanna join?


i would go with stellar nucleosynthesis

j_sum1 pretty much beat me to it, but C12H22O11 + ADP + inorganic P ---> ATP + water has allowed me to open the most doors in my life.

Yttrium2 - 6-6-2020 at 06:09

Ive asked this queston before a while ago (or a similar one)


-

Someone once said something that the alchemists did that opened up a lot of door ways, I forget the reaction, and what it produced. I'm going to have to dig for it. (unless anyone remembers what it was)

karlos³ - 6-6-2020 at 06:30

Sulfuric acid maybe.

I think that was it,( I remember asking about the acids as those are like the starting point for a lot of chemistry) how did they do it again?

SWIM - 6-6-2020 at 11:55

Didn't Aldous Huxley say it was something that 3,4,5 trimethoxyphenylethylamine does with brain receptors?

Note of explanation: Back in the mid-20th century Huxley discovered that this compound makes people really, really like chairs,

"The legs, for example, of that chair. How miraculous their tubularity, how supernatural their polished smoothness!
I spent several minutes, or was it centuries? Not merely gazing at those bamboo legs but actually being them." -Huxley tripping out on chairs.

I believe doors fit into it somewhere too. Like he liked opening doors, or at least perceiving doors, or maybe he just liked Ray Manzarek.

I've really got to start googling this stuff before I post it.


BTW: You're right, and Karlos is right.
I think it was Gerber who distilled iron sulfate or some such thing in a retort (ceramic, not glass) to produce sulfuric acid.

This is a lynchpin of modern industry and even more vital to modern society than his later innovations in baby food.

2 KNO3 + S + 3 C → K2S + N2 + 3 CO2

When alchemists discovered this reaction, I'm sure a lot of doors (and windows, and walls) were suddenly opened.

Hahaha thanks to this I just woke up my wife by laughing loudly in bed early on a Sunday morning

Wohler synthesis. It is the first synthesis that actually created organic compound from inorganic salt. It is pronounced the starting point of modern organic chemistry. Back from this point scientists were unable to obtain organic compounds in lab. Here is wikipedia article about it: https://en.wikipedia.org/wiki/W%C3%B6hler_synthesis

karlos³ - 7-6-2020 at 13:12

But how useful was the Wöhler synthesis?
Certainly not even close as much as the discovery and use of sulfuric acid.

Karlos, I lost the link to my other thread -- in which I was asking about reaction skill trees / what opened up the most doorways..

I believe it was the sulfuric acid, but I don't remember, how did the alchemists make it, again? I can dig it up.

Yttrium2 - 10-6-2020 at 03:31

That wasn't so bad, here it is

http://www.sciencemadness.org/talk/viewthread.php?tid=153979...


I think that the creation of the first reagents is way more earth shattering than the wohler synthesis



EDIT - nevermind, this is a similar thread. Somewhere, someone mentioned rocks that the alchemists heated up to make acids/ can anyone point this out to me?


nvm, it seems as though, someobody has already mentioned it

It's not about usefulness, but about opening doors to organic chemistry. If not organic chemistry H2SO4 woudn't be that useful.

Oh yes but if you mean directly what is most door opening chemical reaction, I would say that explosion of HNIW is. ;)
