If you take triglycerides and saponify them with sodium hydroxide, once done add hydrochloric acid to bring the pH down to about 2. At pH 2 the fatty acid will be re-protonated and neutral (not a salt). Add ethyl acetate and it will form a separate layer from the aqueous solution. Shake it up and the glycerol and salt will partition into the water, the free acid will partition into the ethyl acetate.Thank you uclaLabrat! Might you walk me through the process a little more?
So you have the triglycerides with the glycerol at the end. The acid cleaves the glycerol. But HCL is, I believe, H and Cl. Does it replace the glycerol with a Cl? Or does it leave it in its free form?
And by extracting it, I assume you mean separating the FFA from the glycerol and the Cl and whatever is also in the oil I started with? What does ethyl acetate do when you add it to the mix? Where do the FFAs and what not go from there?
Thanks!!!

Separate the two phases and boil off the ethyl acetate and you'll have (kinda) pure fatty acid. Well...triglycerides are a mix of acids so you'll get whatever was in the mix. And some glycerol will tag along for the ride.

I'll make a decision after I see the video and assess your medical fees.How much you going to pay me? Because I AM going to do this and post pictures right on this forum!!!

Yes, it is at Home Depot and muriatic acid is the same as hydrochloric acid. One bottle is about $10 and categorized under the concrete cleaning section and the HDX branded 2 pack for $13 is categorized in the concrete cleaner section.hydrochloric acid - did you say that is the same as muriatic acid that they sell at Home Depot? Any idea where I would find it there (what section)? I would guess the pool section. Looks like one can also order it on ebay cheap enough it looks like.

The Klean Strip might be diluted more though. They keep the actual percentage a trade secret but it is 10-30% while the HDX has the percentages on the bottle.
It's not practical for HCl to have a concentration of 40% or more.Thanks Torn dude! I'll get the HDX one, seems like a bargain. It is a little weaker than the strongest I'm seeing on ebay and what not, but stronger than many others. I suspect that will work just fine!

If you're really serious about this stuff do wear proper PPE and do in well ventilated area... this could be recipe for serious disaster lol. some of the gases you can end up creating can be super toxic. Wear safety goggles, respirator etc (covid mask won't do crap, you need something proper)
You are to by absolutely no means EVER TO USE A FLAME HEATING SOURCE WHEN DOING THIS. Heating mantles are best, specifically variable voltage, or a hot plate with some sort of bath.
Realistically for ethyl acetate you can just let I evaporate instilled of distilling it.
Again. Do not do this at home. You don't have the equipment to do it safely.
Eye protection is the primary thing with the fumes. Goggles should definitely be worn. Clothes should be something you don't care about or a Tyvek coverall.Thank you Red Squrrel. Is all that really necessary if I'm just going to make a few hundred ML of the stuff? I'm talking very small quantities for the trial runs until we perfect the process. I just can't imagine that if I make 500 ml of the stuff that even if the gas it puts out is pure lung corrosive crap it would do much damage, given the small quantities haha.
