Derick,
Still, treat a small sample with concentrated sufuric or phosphoric acid
and observe.

Thanks for the response. I feel that I may not have explained that there
isn't a layer it's almost a solid mass. It is about 95 deg f outside and if
I turn the soda bottle on its side it slides inside the bottle as one lump
retaining the shape of the bottom of the bottle. If I shake it hard it does
brake up somewhat. Kind of like when the old super ball was broken.
I feel that I now have super glop.

I have a problem with disposing of the mess I

Take a small sample and see how much concentrated sulfuric or phosphoric
acid it takes to crack the soap portion of the top jelly layer.
This is the same thing that is done with the glyc cocktail to recover the
free fatty acids.

Hi Keith More
Thanks for you response.
I tried the world famous chop stick titration technique. Wow what a
difference in my titration #.
I did a 1 ltr test in a soda bottle, with excellent result almost
instantly.
But here is where I got into trouble.
The next batch was 20 liters I had some methoxide mixed from a prior batch
that was also a failure and I couldn't figure what to do with the toxic mix
so I tried to dilute it to 10 g.p. liter. I did my mixing of the 20 liters.
As it cooled it turned into what looks like lard. I felt that I may have
overdosed it. So I then took some test bottles and put 20% failure oil and
75% fresh wvo set it in the sun to melt/ liquefy. (105 deg F) shook it hard
also a 50/50 mix in the hot state it seamed to separate better 25/75 than
the 50/50 but as the sun went down and it cooled the 25/75 started to jell
and the glycerol layer vanished but the 50/50 looked much better with a
glycerol layer jelled at the bottom. I m not asking for a fix. But is the
jelly a typical sign of over dosing? I have a problem with disposing of the
mess I have made if there is a way to salvage it.

Subject: RE: [Biofuel] RE: Phenolphthalein solution
Hi Derick
May be there is some help for me out there. I have made lots and lots of
test batches. Most of them bad not good. One border line. And one 15 gal
batch with fairly good results. I have used all the options given for
titration in the J.T. Forever. Test strips work
... poorly, if at all, and are not recommended by JtF.
but after introducing it to
the mix I find if I need to add more solution the color will not change so
I
need to add strip after strip as I add the solution accuracy is probably
off
by the time I get done P.H. meter a good one I found to be about the same
pH meters work well, especially if it's a good one, you shouldn't be
having problems.
and I have used phenolphthalein and get excellent response but im no
chemist
Very few of us are.
can anyone tell me how much phenolphthalein to use on the test I have been
using 2 drops @ 1% phenolphthalein. The instructions from J.T.F say "use
1%
phenolphthalein solution (1.0w/v%). If you can please help. Thanks Derick
You say: "The instructions from J.T.F say "use 1% phenolphthalein
solution (1.0w/v%)."
The instructions at JtF say: "Add 2 drops of phenolphthalein solution."
"Dissolve 1 gm of lye in 1 litre of distilled water (0.1% w/v lye
solution). In a smaller beaker, dissolve 1 ml of the cooled oil in 10
ml of pure isopropyl alcohol. Warm the beaker gently by standing it
in some hot water, stir until all the oil dissolves in the alcohol
and turns clear. Add 2 drops of phenolphthalein solution. Using a
graduated syringe, add 0.1% lye solution drop by drop to the
oil-alcohol-phenolphthalein solution, stirring all the time, until
the solution starts to turn pink and stays that way for 10 seconds."

Thanks to all who provided sources and altarnatives for the
phenolphthalein! Now I can start using the 75+ gallons of WVO that's been
sitting around my garage.
