AI Thread Summary
Dichloroacetate can be synthesized through various methods, including the chlorination of acetic acid or chloroacetic acid, hydrolysis of pentachloroethane, electrolytic reduction of trichloroacetic acid, and the reaction of alkali cyanides with chloral hydrate. The chlorination of acetic acid is noted as the most direct and cost-effective method for industrial production. However, the process poses significant safety risks, particularly due to the potential release of hydrogen cyanide, which requires strict safety precautions, including working under a fume hood and using appropriate protective gear. The discussion emphasizes the dangers associated with these reactions, cautioning against experimentation without substantial justification.

How would someone make dichloroacetate?

I am not planning on using it to treat any humans with cancer, just wondering.
 
Chemistry news on Phys.org


See the OrgSyn page. The reaction looks gross: chloral hydrate + sodium cyanide...

Also see the "Discussion" section on that page:
Dichloroacetic acid has been prepared by the chlorination of acetic1 or chloroacetic2 acid, by hydrolysis of pentachloroethane,3 from trichloroacetic acid by electrolytic reduction4 or the action of copper,5 and by the action of alkali cyanides on chloral hydrate.6

Chlorination of acetic acid seems like the most direct and the cheapest way in terms of industrial-scale manufacture.
 


Wow, I wouldn't touch that process if you paid me without a good reason; curiosity wouldn't be enough. If that thing foams too much, or you forget to keep the evolved hydrogen cyanide down, you'll be dead before anyone could help you. Whatever you do or don't do, curiosity or not, for the love of god do it under a hood and with the PROPER gear.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
