Hi, some update on my 'problem' with separating glycerine.
I've continued my tests, and come up with the following.
Hello Filip
I've done quite a lot of work with this, though not as much as Todd,
but it was with phosphoric acid, not sulphuric acid - I don't know if
Todd's used sulphuric, but I think not. I do know that acidifying
soapstock is usually done with sulphuric acid, so, since this is very
darn, I wish I had my pics from the seperations we did in Girl Marks
Ecology Center workshop. Mark, you have any online Pics available on what
the seperation should look like?

I don't think anyone photographed it and I don't have a digital camera. But
there's photos at the jtf section on glycerine/ffa separation and Im sure
that filip saw them...

Actually I took pics of the jar that you brought to the workshop. At
least that's what I think it is (or what it looks like!). It could have
been an emulsification exammple, although the middle layer is molasses
color, so it seems to be Glyc seperation.
Dunno, there was a question from Ken
I think you're thinking of something else. not sure what though. the middle
layer of the jar I had in class was clearish yellowish. there wasn't all
that much visible salts layer if you looked at the jar head on.
the reason ken mentioned soap is cause that's what's being broken down from

Hello,
I'm new in making Biodiesel, and while trying, I came up to something I do not
understand.

into FFA.

H2SO4.
The oil source was WVO,
It sometimes takes time for you to see the results (24 hours?) . I don't
know enough aobut this to know if the calculation is correct, however you
can do a trial and error test series to figure out how much acid to use.
The first time I did this, I did a small test batch and with no results

Both phases, or just the glycerine phase that had already settled out
using an NaOH catalyst? It's not clear
