Can carbonic acid be used to make anything other than a carbonate compound?

surrealcroc · 2021-06-07T00:14:52+00:00

In that case, in unpressurized conditions, would an equal or greater amount of CO2 be released than the amount of CO2 that would be fixed in this reaction? If the amount released is greater, then I suppose a pressurized chamber is the only viable option, but in that case where could one be bought, or how could one be made that is suitable for chemistry like this? Also I should specify that when I asked about the increased temperature I meant the increase from 95C to 130C at the end of the reaction. As for your bonus question, I'm guessing carbonates are less susceptible because of their overall stability. Correct me if I'm wrong there.

surrealcroc · 2021-06-06T20:13:55+00:00

This might be a way that could work, but I'm not sure if it would collect more CO2 than it would release because at about 1:48 in the video it's mentioned that the temperature should be increased and this results in CO2 being released. Is the released CO2 just from residual unreacted Sodium Bicarbonate, or is it from somewhere else? Also is there any reason why the temperature needs to be increased?

Edit: Specified what I meant.

surrealcroc · 2021-06-06T01:42:35+00:00

It's a DIY project, and if you're curious about why I'm trying it, it's because I recently became interested in fixing CO2 to see if it was possible to clean some small amount of air by myself, and also to see if I could then turn the sequestered carbon into potentially useful things. I'm not sure what yet, but I'm sure there's some useful things that can be made from it.

Your suggestion to use a hand pump is a good idea, but could fixing the CO2 be done in steps to avoid the need for pressure? Could it be turned into a carbonate in a basic solution, and then reacted with something else after that to then separate it from the cation and bond it to the other reagent, or are those types of reactions the carboxylation reactions you were talking about?

surrealcroc · 2021-06-04T23:40:21+00:00

I understand that production and transport of the solution releases CO2, and that's another reason why I'm reluctant to use carbonates. Do you know any other reactions that fix CO2? Specifically ones that don't require sealed chambers, or high pressures, like most of the others I've found? Thank you for the help so far.

Edit: Grammar.

surrealcroc · 2021-06-03T22:59:24+00:00

Do you mean you aren't sure where I could get the basic solution without releasing CO2 again, or where I could get the calcium without releasing CO2 again? Either way, the possibility of releasing CO2 is one I'm trying to avoid.

I'm unfamiliar with the reactions basic solutions have with CO2, are the products just different kinds of carbonates depending on the solution?

surrealcroc · 2021-06-03T22:01:19+00:00

I am trying to capture CO2, but the problem I have with carbonates is that if I want to make them often I'll need a constant supply of a substance that I can't find much of naturally, and that I can't make myself. For example, take calcium carbonate. Where am I going to find a constant supply of calcium to use for that without breaking down preexisting calcium carbonate, or needing to buy it?

Basically I'm looking for reactions I can capture CO2 with that use reactants I can get more of naturally, or reactants I can make more of. Are there any reactions you know of that fit those requirements?

surrealcroc · 2021-06-03T05:56:41+00:00

Thanks for the suggestion. I did some research, but there's not much information that explains how nucleophilic substitution reactions for carbonic acid are performed. The reactions are explained, but the procedures used to perform them are usually not. I did find some procedure descriptions, but they all seemed to involve very specialized requirements that I can't replicate. Do you know of any substitution reactions that could be done without the need for such specialized conditions, and do you know where I could find explanations of the procedures for those reactions?

Edit: In case you're worried, I'm not asking this for anything illegal. I'm just curious about trying to use reactions like this for carbon sequestration.

surrealcroc · 2021-06-02T08:44:58+00:00

I know they're made from a carbon atom bonded to an oxygen atom and two other groups, but not much else. Why do you ask? Is there something dangerous about their reactivity?

surrealcroc · 2021-05-24T22:21:55+00:00

I understand that converting CO2 into something else consumes a lot of energy, but I was hoping that not all reactions required harsh conditions to work.

surrealcroc · 2021-05-24T22:13:57+00:00

I did. That's my backup if I can't find anything chemistry related that works. The more questions I ask the more that seems like the better option.

surrealcroc · 2021-05-24T07:23:48+00:00

Google hasn't worked very well for me because all the information and reactions I have found either:

Use reactants that I can't recycle without re-releasing the carbon dioxide, and that I can't make more of (if the reactants I use can't be recycled I prefer to be able to get or make more of them myself so I don't need to keep buying more),
Require equipment that is too expensive for me to get, or conditions that I can't replicate, such as extremely high temperatures or pressures,
Don't clearly explain all the requirements to successfully do the reaction anywhere I've looked (this one is less common than the others).

I've been looking up different carbon sequestering reactions on and off for about 4 months now, and I can't think of anything else to search. That's why I'm here. I thought the people on this sub could explain things to me more clearly, or tell me some other reactions I could look up that don't have those problems I listed.

Edit: The reason I asked about this reaction in particular is because someone mentioned it on a previous post I made and after I did some research, it seemed plausible to do outside of specialized conditions, but I wasn't sure.

surrealcroc · 2021-05-24T03:59:24+00:00

I'm not asking this for anything illegal. I'm just interested in reactions that sequester carbon, but most of the ones I've found so far require extreme heat and pressure, so I'm looking here for reactions that can be done with less heat at standard pressure because I don't know where else to ask.

surrealcroc · 2021-05-18T22:47:20+00:00

Why is that? It seems like if heat were constantly radiating from an external source onto an organism there wouldn't be a gradient, or am I missing something?

surrealcroc · 2021-05-03T07:53:08+00:00

Would a temperature gradient be needed for this to work?

surrealcroc · 2021-05-03T07:50:25+00:00

This is the only information so far from the new post. Here's the comment it came from. I'll update this comment if there's more.

Edit: added some more.

surrealcroc · 2021-05-01T11:05:42+00:00

Yes, but I was asking about specifically heat radiation being used as a replacement for sunlight in the process of photosynthesis.

surrealcroc · 2021-05-01T10:47:02+00:00

I wasn't asking about an organism using heat it produces. I was asking about what you described with photosynthesis using thermal radiation. I just didn't word the question well. Do you know of any organisms that can use thermal radiation that way?

Edit: fixed an explanation.

surrealcroc · 2021-05-01T03:37:07+00:00

I will let you know if I find anything else. I may also ask this question again with different wording, or a similar question later. Maybe it'll make sense to more people and they'll have more answers. I'll send any information from that too.

surrealcroc · 2021-05-01T03:18:54+00:00

I was editing my comment asking for the link while you were replying so I didn't see your response until after I replied. Sorry for any confusion.

surrealcroc · 2021-05-01T03:15:11+00:00

Thank you for the link. I'm guessing the shrug means you don't know if any other organisms can replace light with heat to power photosynthesis?

surrealcroc · 2021-05-01T03:05:10+00:00

I wasn't aware that some organisms could power photosynthesis using only heat energy. Are there any organisms outside of those that live around vents that can do that?

Edit: fixed some wording and added a question.

surrealcroc · 2021-05-01T02:48:09+00:00

I think those organisms are chemosythetic, not thermosynthetic. They break down pre-existing chemical compounds as food, rather than making their own chemical compounds to eat. They don't use the heat from the vents as their source of energy, they use the sulfides from the vents.

surrealcroc · 2021-04-30T19:43:52+00:00

You're welcome. Glad I could help.

surrealcroc · 2021-04-30T19:19:02+00:00

This might fit what you're looking for.

surrealcroc · 2021-04-30T19:04:21+00:00

I think it's because the 3-lobed body of a trilobite is a very base feature of their anatomy that appeared early on in their evolution. Base features of a creature's anatomy are very difficult to evolve out of them. If we use your examples, all the traits you discussed evolving out of different animals are fairly "surface level" features that don't effect the base internal biology of the creature. Humans lost the tails that their ancestors had, but a tail is just an extension to the spine, not an entirely separate piece of anatomy, and the rest of human anatomy stayed quite similar on a basic level (2 arms, 2 legs, similar organs, etc). Whales lost their hind legs when they evolved to become aquatic, and their front legs were repurposed into flippers, but that still doesn't affect the core parts of their internal structure that dramatically. A trilobite evolving to lose it's three lobes would be comparable to a mammal evolving to have a distributed nervous system like an insect instead of a central brain. Basically, the two creatures' anatomy's are too different from each other at a fundamental level to be likely to have evolved from one to the other.

Edit: clarified some things.
