There’s a lot of informative info within this thread as well. Not each setup will be the same. Some reactors have different lid applications & joints. If you’d like help on your setup I’d start with a photo of what you may be working with & many folks here can help you from there.
Right on! Thank you.
I see that your SOP mentions spd glassware. I have that well covered. We have a huge reactor so I am trying to see if my current small spd glassware will work for R&D. Have you every had worries with the simple glassware? I see some people saying that “explosion proof” reactors are needed. I am just trying to develop a proof of concept.
I love u, but this is false.
Don’t subject stainless to pTSA, citric acid, HCl or strongish bases. It will corrode and eventually crack.
I can provide more info on that if requested.
Even at a 1.5% concentration ?
I’ll take that info please it’d be nice to have as a reference
It mentions both spd & reactors, there’s a detailed description below for preparation work.
Technically here, it is event not at 1.5% concentration, since it does not dissolve in the hydrocarbon…
But if you have a few water in there, then you have some strong acid concentrated in certains spots. For sure steel will not like this. Unless it is a very short contact, and followed by extensive cleaning.
This is for pTSA @ 70% concentration. 70% concentration @ 45C had around 50um per year in corrosion.
70% concentration @ 90C had a corrosion rating of > 1mm per year.
Probably very minimal at low concentrations @Roguelab, but why risk it? Also if you want to use strong acids like HCl and H2SO4 you won’t be able to.
So @iLLnyeTheShatterGuy and @DUMPSTERFIREOG are wrong yes?
I’m not wrong and a cursory google search will show that. What he said literally confirms what I said. Not sure what you’re getting at here.
I think you may be getting neutral substances confused with buffers. A buffer will hold the pH at a specific level while the neutral salt (NaCl) shouldn’t have an effect on pH to my knowledge.
The reason being that HCl and NaOH are such strong acid/base that they will almost never take up either OH- or H+ from solution, making the buffering capacity of salt (NaCl) zero.
So if the ph is 5 adding a neutral salt won’t change that ph?
Let me backup from the terminology “a neutral salt”. That’s probably going to include some salts that do have buffering capacity.
Sorry about that, I mean that specifically NaCl doesn’t have the ability to buffer acids/bases
It won’t change it. It that situation “neutral” means that the salt has no acid/base properties. It does not mean that it promotes a neutral pH. The water serving as solvent is the agent in this case. Actually here it is not its acid/base properties which are employed, but rather that it dissolves ptsa, and thus allo to recover it from te heptane/product mixture (and further turns acid as long as ptsa comes in).
The salt can however have a small indirect effect on the pH, since the pKa if the other acid present can be influenced by the ionic strenght (the total solute concentration in solutoon including background salts).
So the weak basicity of the Cl− ion isn’t sufficient to raise the ph in a solution? Not arguing just asking thanks.
For instance, phosphate salts provide quite a bit of buffering because of the multiple phosphate ion states
Can’t wait to see these awesome projects come to fruition!
It is too weak. It may have some effect at very high concentrations, at several molar, but will remain weak anyway.
Thanks to @iLLnyeTheShatterGuy for this sop. This being my first real attempt at Delta 8. I ran this rxn as close as I could to the sop. It worked fantastically. In-house analytics Coa came out at 88%d8 10%d9 2% cbn. Yield was 87% from starting isolate weight.
Thanks again.
