Worked fine for me.

I would do a proper work up and run NMR before you call it a total failure. You should also monitor with TLC during the reaction so you can have some idea of what’s going on.

Have you done any sort of crude work up or purification? Did you monitor with TLC at all?

Have you looked at it by NMR or maybe GCMS?

Hello.
I am just wondering whether it is possible to combine the hydroxy group of 4-Hydroxy-1-naphthalenesulfonic acid sodium salt to another compound with -COOH group via esterification? If so, what are the appropriate reagents used for this?I see no reason why not. It should be pretty easy to look up an exact procedure as it’s not an overly complicated molecule.

We've recently had a few posts by newer members asking for advice and expert input on ideas they are unwilling to disclose publicly for reasons of IP protection. Staff feel that this goes against the spirit of this forum as a place for open discussion, and we have therefore updated the rules under Section 2 to include the following:
Quote11. Solicitations requiring non-disclosure or confidentiality agreements, or insisting that discussions must take place privately, are not permitted. We are here to discuss science, in the open (and "I have an idea, can someone do the math for me" typically woefully underestimates the amount of effort this involves).

What do you think the answer might be? Have you gone through each of them?

Why's that? What other kind of reaction would you see with a fatty acid, ethanol, and hydroxide?
You won't get the ester. You have an acid and a base, you're just going to get deprotonation. You need an acid catalyst to get the ester.

Does the carbonate dissolve when you add it to the reaction? I am not familiar with its solubility in DMA or DMF. If not, perhaps you could consider adding crown ether or switching to Cs2CO3? The latter is reasonably expensive, but if you have it on hand it might be useful.

Do not copy paste entire articles. If you wish to make a point using them, quote relevant sections and cite where you got them from.
Also, mod notes are not open for conversation within the thread. If you have a problem with one, report it or PM staff.

Since the OP hasn't come back with anything to back up their wild claims, I am closing this.

I am not entirely sure if this thread is supposed to be about the HBO series or the actual event, but whichever it is, I think we can dial down the pedantry and stop with semantic arguments.

PervPhysProf has been banned for after a stream of incoherent and also some weirdly racist nonsense.

Polinski, you are being obtuse and dragging this thread off topic. Please stop. If you have nothing relevant to contribute here, you are welcome to either find a more appropriate thread or create your own.

Stick to the topic, and quit the straw man arguments, Polinski. This isn’t about abortion, nor is it about selling children. Please try and approach your posts with a little more scientific rigour while you’re at it.

Lord.
You’ve been here what? 3 days? You’ve posted nothing but unabated nonsense, and you refuse to accept that maybe your ideas are not scientifically sound. Your grand proposal is to pump a gas into salt water to solve global warming. How do you propose it stays there? It won’t all turn into carbonate salts. And do you really think that destroying entire ecosystems is a good solution?
You need to put at least a little thought into your posts, and a good deal more into your ideas. I am closing this thread since you have virtually nothing to support your hypothesis and you refuse to do anything to change that. You may not reintroduce this topic on this forum.

I am closing this. OP, if you can come up with a testable model and some math, please PM myself or another member of staff to have this reopened. Until then, you are not permitted to reintroduce the topic.
