C4H7NaO3+HCL=  ?

Which acid is stronger? What happen if a strong acid get in touch with a salt of a weak acid?

[yuguo]

This is the reaction between strong acid and sodium salt. I want to get acid and ask how to remove sodium from it.

The acid probably you can destill.

[Babcock_Hall]

Have you considered using anion exchange chromatography or possibly cation exchange chromatography?

[yuguo]

C4H7NaO3+HCL ––C4H8O3+NACL
The chemical formula after the reaction is like this, right? If yes, how to remove nacl from it?

[yuguo]

C4H7NaO3+HCL ––C4H8O3+NACL
See if this reaction is correct? The key point is to remove nacl from it.

[Hunter2]

Extraction with Ether followed by vaccuum Destillation.

[yuguo]

C4H7NaO3  –→  C4H8O3
Is there any other way? Sodium hydroxybutyrate reacts to produce hydroxybutyric acid.

[Hunter2]

Suggestions given above. Ion exchanger.

[yuguo]

Can you explain it in detail, thank you

You may have misunderstood. I mean, is there any other reaction? What does C4H7NaO3 add to get C4H8O3?This is another study.
I know all about extractive distillation.

[Hunter2]

There is no other way to exchange sodium to hydrogen. To add the acid is simple. The main work is to separate NaCl and purify the product.

By the way for what you need the 3-Hydroxibutanic acid?
Any drugs synthesis will not discussed here?

[Borek]

I know all about extractive distillation.

But you have no idea about the most basic acid base reactions between salts of weak acids and strong acids? Strange, most people learning chemistry learn about acid base reactions long before they get to the practical extraction methods.
