Does anyone know how to cleave glycerol from triglercides, leaving behind free fatty acids?

[SaltyNuts]

Well screw that one actually, here is 5 from ebay, including a big 1000ml one, for just a few dollars more! Any reason not to get this one?

Thanks!!!

Ordered. Can you guys other than UCLALabRat and Torn Mind actually help a little bit? I get it, funny trolling, but try and bring a little something to the table to help with these great endeavors, LET'S MOVE MOUNTAINS TOGETHER....

Can't you just buy the acids you are after?

Apparently not, at least not easily. I can buy the oils very easy of course. But the free fatty acids, not so much. Someone posted a link to some one could apprently buy earlier, but they were like sunflower oil, which doesn't really have the fatty acids I'm looking for in significant/sufficient quantities. But if you think you have a source Toasted, I'm all ears!!!

UCLALabRat, I hope you ain't gone nowhere! I'm going to make some soap this weekend, and then shortly after that some free fatty acids! So many questions. Here was your quote from earlier:

"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.

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. "


1. Do I absolutely need the ethyl acetate? Or will not the free fatty acids separate from the aqueous solution on their own?

2. I know I need to add heat to create the fatty acid soaps, but do I need to add any heat in the HCl adding phase? I would guess not.

Thanks!

I'm more curious as to why he wants them.

They have many uses, such as in beauty products. They are, in short, awesome. I want to be forever young.

OP, have you been diagnosed to be on the spectrum?

If you are referring to the beauty spectrum, indeed, I am a perfect 10.

"have to"? I don't have to do anything. I buy her one because its just chump change. Sorry you are poor, and that you are jealous of me both being beautiful and money.

 

[dullard]

gamma-linolenic acid
alpha-linolenic acid
linolenic acid

its just chump change. Sorry you are poor, and that you are jealous of me both being beautiful and money.

So just buy them:

So well off that expensive iPhone is NBD, but can't afford to buy soap.

Those are for laboratories to use. Did you see those prices? Way, way WAY to expensive to be practical, when I can make large amounts for a small fraction of their prices.

Why not cut the process short and sell your decadent all-natural soaps like Dr. Squatch(annoying commercials btw)?

This is going to end up like Fight Club isn't it

Oh you mean like build up a $250 million annual gross revenue business and sell it for a cool billion? Yea, I might just do that!!!

You are going to put the stuff you made, out of the chemicals mentioned, on your face? The stuff that you made?

I mean I find that products to wash my face with are pretty easy to get hold of without the risk of dissolving myself but you do you!
