Discussion Feasibility of making your own SN

[bFre3]

With pure SN getting harder and harder to buy directly, I've been looking into the possibility of getting SN from other products. I'm not a chemist, so I'm not entirely sure if this is feasible. It's nothing but a little idea for now, but I think it's worth a discussion.

I first looked into extracting SN from curing salts. Curing salts seems to be a mixture of SN (NaNO2) and Sodium Chloride (NaCl) which is just table salt. There already seems to be discussions online about separating these two, and from what I've read it seems possible, but difficult. I don't think I'm qualified enough in chemistry to give an opinion though.

I also looked into getting SN (NaNO2) from Sodium Nitrate (NaNO3). Apparently, a few hobby chemists have been doing this to acquire SN after it became difficult to obtain them. There are a few videos on YouTube about it.

Once again, I don't have enough knowledge on chemistry to say anything for sure. I know nothing past basic high school chemistry. This is also another reason why I'm posting this, for someone hopefully more educated than me to provide their opinions.

I believe the main points of concern would be:

1. Purity of obtained SN
2. Checking if the substance obtained is even SN (although, I'm pretty sure this can be done with test strips?)
3. Cost
4. Safety of the process

For the synthesis of SN this pathway seems like the best to me as a lay person



However calcium sulfide isn't actually easier to obtain than SN at my location, so I haven't really pursued this option further.

I'm going to keep tabs on this thread in the hope of someone having something more helpful to contribute, but maybe this helps in some way.
