Are there confirmed cases of .5l formic + 1l sulfuric?

[Deutschv2]

Can't find any cases of just dumping .5l formic into sulfuric 1l. COgenie proves it's possible, but the possibility of acidic fumes makes me wonder if this is actually a doable or good method. thanks

cogie uses water somehow to get rid of the fumes so that's why it concerns me if just mixing the acids without anyting else is such agreat idea

I've looked into using the COgenie, too. But I couldn't find the right supplies to make it.
There's also very little detail in the pph as to how to make one yourself.

I'm guessing you mean the design where you turn it upside down to start it?
I was looking at making the one that's built using pvc plumbing, where it drips the formic into the sulfuric acid.
That design doesn't have a water reservoir or anything, but I wonder how important the drip-feeding is.
There's probably a good reason for not dumping it in all at once, although I don't know what that would be.

This is from what I can remember, as it's a few weeks ago that I looked into this. Might be some mistakes in what I typed here.

The reaction between the two acids produces water and O2, so judging by that there won't be any dangerous fumes (well apart from the O2, of course).

I guess the reason for not dumping it all would be to have a sloe and controlled reaction rather than a massive burst that knocks you out then it stops producing and you end up with brain damage. Maybe?

There was a guy here posting about his COgen plan I'll find his posts in a bit.

When mixing the 2 you get H2SO4 + HCOOH ---> H2SO4 + H2O + CO and heat. some of the acid will turn to vapour and strip the lining of your lungs, so you need to rinse the resulting gases in a waterbath. dumping it all at once you risk a/splashing concentrated acid everywhere and b/ generate a lot of heat.

i'm happy to be corrected

Thanks Xali, edited my original comment.

ye, the one that inverts uses water, kind of surprising that the other one doesn't

i think it's more to to do with the acidic fumes, cause acids produces a lot of CO

hello xali1970, you seem very knowledgeable on this subject: so, a question... is rinsing in waterbath neccesary? assuming you just dump the formic into the sulfuric and let it build up in a car for a few minutes, if you go inside, you will be knocked out very quickly, right? so does it really matter then that there is traces of the acid in the air? thank you very much i appreciate..

assuming that you spend around 20 seconds pouring the .5l formic into 1l sulfuric, that's what peoples on 8ch says to do, i was unclear in the original post

Well... the fumes - and it will be more than traces if you mix those quantities that fast - will start disolving the tissue in your lungs and all other areas in your airways that are moist the moment you get in. It will be quite painful (chemical burns are no joke) until you pass out, and should you survive it you'll have a very reduced lung capacity. So yes, in my opinion a waterbath is important.
The original published COgenie design had one.

Good post yes I recall a member... Phillistineears I think his name was? Search his posts for similar info, OP, this was his method of choice and pretty sure he worked in a relevant industry.
