I just bought up some Test Tubes, Beakers, Gloves, Crystallizing Dishes, A Scale, Funnel, Coffee Filters, and A Mortar & Pestle.

The chemicals I bought were Na(NO3) & Ca(SO3) both in 1 pound bags

Those are all the items that I need to synthase my SN


I did the math on how much SN I will end up with, and if I do optimally I will end up with 250g~ with a high yield, but even on a lower yield (50%) i will still have over 100g of SN

They will arrive in a few days, and I will begin... To cook!

This will be my first non-classroom chemistry lab that i will have done which is very exciting. I also bought some Sulfuric Acid (H2SO4) for testing due to SN being reduced, and the acid will oxidize it, and create Nitrogen Dioxide. Although its toxic gas, the concentration of the acid is .06 M so it should not make too much acid, and if that fails I can still do other tests to see if there is enough SN.

Interesting! How do you plan to reduce the nitrate-sulfite mixture? Burner or oven?

I'll do it in the oven since that is just easier, and also i don't have a burner. I would also not use a burner in this since i will be doing in 100g~ increments of compounds on each cook and overheating a spot could make Nitrogen Dioxide instead of SN (N20 will still be made, but in much smaller amounts in the oven) I just don't want to waste it all, so I'm being extra careful with it all, so since an oven heating it up more uniformly that's why I'll be cooking it.

35 mins at 230 C if your wondering my cook time.

Sounds like a plan. You're right. An over is way better to facilitate a more uniform and controlled reduction. This is where I failed miserably. I have no oven so I got cold spots and yielded poor quality salts. It's not like I needed to make my own SN. It's easy to procure SN in my country, but reagents are cheap and I was also doing my synthesis of sodium cyanide at that time so I figured I'll try nitrites.

We're definitely gonna need an update from you. Hopefully you'll get a good yield! Like you said, you're better at chemistry anyways. :))

If this is found viable, it can be epoch-making for those who aren't accessible to SN. Good luck. Let us know any updates:haha:

If this works can you do N next lol?
I'm planing on ctbing after I make a guide to SN making, but I guess i can make a proof of concept post if I find any good reactions that could work

Personally, if I were capable and going to all this trouble, I'd just forget about the SN and, instead, just synthesize N, as long as the necessary materials were obtainable. N provides a much better death, imo. But, you're the cook, so do what pleases you.

Yes but there is one scary thing you need to do... MATH dw tho I'm gonna make a math sheet where it will walk you through step by step.
It will require you to still use your brain, but it's chem you learned in high school so it's not super hard

Uhhhh no I'm only messing around with 5 atoms of interactions and SN is only 4 atoms. While N is 30~ atoms large and the reactions that would need to happen are a bit above my knowledge level. I am not Walter White sadly, but if anyone here has any ideas I'm open to it. I also want to keep it cost effective, it will be only 120$~ for SN making. While the number of reactions required for N will likely lead to a higher price point.

i did take some general chemistry classes in college (familiar with dimensional analysis, making ice tables and shit like that) so it wont be totally foreign to me. i appreciate you taking the time to make it and share it.

I think, there is too much hype about both. These two substances have disgusting taste, and the nitrite often causes nausea and vomiting on top of that. If I were ready to delve into chemistry and choose amongst the best poisoning chemicals for comfortable CTB, I'd rather consider carbon monoxide or potent synthetic opioids in the first place.

Concentrated CO should be easier to make and to test than nitrites or barbiturates and its inhalation is nearly discomfort-free, with unconsciousness produced in a matter of seconds. It may be somewhat difficult to obtain concentrated sulfuric acid or phosphorus pentoxide for related methods in some countries, but sodium oxalate should be easily obtainable almost everywhere. The only drawback of its pyrolysis is that it needs a significant temperature for decomposition at a decent rate.

N synthesis is whole different animal. PPH once described it but someone tried it and ran into all kinds of difficulties and they had chemistry experience. Even Walter White couldn't do it.
For SN I guess there's several ways to create it from components. I thought one included lead. And I think stove top method. (Although these things are always best done outside in case of fires)

the point is kinda that pentobarbital is a "heavy" chemical. no single person reasonably could make it (or a decent amount of it) without the use of industrial machinery and a small team of chemists who are familiar with the process. basically you need Gus' underground lab. it's just unviable for one person to do, unlike SN which is a very light salt with only 3 atoms. the process of reducing NaNO3 to NaNO2 is relatively simple if you know what you're doing and it could conceivably be done at home.

the problem with this thread I am noticing is the question of purity. we want >95% purity in order for the dosage in the guidelines to work. doing it at home with no equipment or experience usually will give you a shitty yield which will still contain a fair amount of SNitrate. if the end result was like 70% purity, you would have to take a LOT more SN to reach a fatal dose, which will put a lot of people off since it tastes absolutely terrible as it is. and the side effects would be from both nitrate and nitrite which may be unpredictable.

My plan to keep it pure is to add more Ca(SO3) than is needed since it is insoluble so that there is much opportunity for rxns to take place.
I am planning on making a guide on this after I try it

Will you test the purity of the desirable product somehow or just hope for the best?

I get it, but you said even Walter White couldn't do it ~ ofc not, bc the script was written that way. It just seemed kinda strange to use a fictional character's antics to make a point about the difficulty of synthesizing it. There is a "recipe" floating around the Web for a "home-cooked" brew of N, or pento. Whether, or not, it actually results in pento, I have no idea. I think it's even been posted here before.
