Glycolic acid + HCl -> Chloroacetic acid

deadrush - 29-12-2023 at 12:16

I've read this is possible from a few sources and a patent. It doesnt seem likely to work. Anyone ever done this successfully?

I assume it will require some sort of catalyst.

Later today im going to try glycolic + NaOH -> Sodium Glycolate. Then sodium glycolate + HCl -> sodium chloroacetate. If successful I'd acidify.

Thanks in advance!

You think sodium glycolate is going to react with hydrochloric acid to give sodium chloroacetate instead of glycolic acid?

What is your reasoning behind this?

I know this isnt really a source but it is what gave me the idea initially.
Apparently it does work in reverse according to sciencemadness!

I know i found one other reference to this in a chinese patent. They required the use of a very differnt, complex, and impossible for home catalyst.

Some people synthesized it from acetic acid with sulfur and bubbling there Cl2 gas. S reacts with Cl2 into chlorinating agents S2Cl2, SCl2. There could be also an intermediate acetyl chloride and its further chlorination gives chloroacetyl chloride which hydrolyzes with water into chloroacetic acid.

Balancing an equation doesn’t mean it’s even remotely possible. Next time you start a thread claiming you have “a few sources” without being able to provide said sources, I’m sending it right to detritus. Scientific discourse doesn’t begin with “so I heard somewhere…”
