I'm just surprised that it looks I need much more lye. I didn't expect,
when titrating with phenolophtalein, the colour should be so intensive.
For me it was clear enough last time (1.35g KOH more / 1l).
Thanks for word of advice.

. Processing time is 2h, temperature in range of
60-64 degC, agitation using medium-size aquarium water pump - I think it's
enough for 5l test container. Maybe I should redesign the container's
inlet and outlet (both in the same lid - two plastic pipes of different
length).

Hi all,
Could you tell me how can I tell the difference between emulsion
caused by unfinished process (glicerides left in the product) and
caused by soap formation (too much lye) ?
I have a feeling I misinterpret the result I get from the wash
test...

Not much, but who knows what's enough...
Another is that I should probably try to titrate with more
intensive colour of phenolophtalein solution to say that's
it.
I'm going to do one more try with more lye.

was .750ml or so. I wonder, what would be the result when a really fine
quality oil was tested (sunflower perhaps)...

Increase the lye in the batch until you can shake the hell out of it in the
wash test and still get perfect separation within minutes.
This is what I would be doing.
Thanks for your suggestion.

It's probably normal, as it sounds impossible to make fresh oil with
absolutely no FFAs. The question is - what amount is 'normal' and what
is definately not ?

Biodiesel phase isn't clear (though the colour is quite right) nor does
it separate quickly in the wash test. There's still something wrong...

mono-

Theoretically, I could just add low concentrated methoxide
or downright pure methanol, reprocess it once again, and lye
still present in the batch should take part of a catalyst.
Am I correct ?

of white
dust (a bit like a light sand). Also, the solution wasn't
absolutely clear and translucent, and it lost about 50ml in
volume. I thought the container was really hermetic...
The solution I'm talking about took 400ml of methanol and 7g
of NaOH.

making it less pure NaOH. When
dissolving in methanol, NaOH gets into the solution and residue is
Na2CO3. The only question is whether or not, sodium bicarbonate
affects the biodiesel reaction ?

I want Google or Mozilla to come out with an operating system.
No need to. Just wait for unix desktop environments to become mature

really need
magnetic mixer to prepare methoxide solution :) If you want to play
with it, that's a different matter, but it's quite enough to use
ordinary thick plastic HDPE bottle carefully swirling it. It takes
a bit of time, but hydroxide must be completely dissolved.

not
all fuels do have it. Does anyone know what's in those additions ?
I'm not talking about nitromethan here - that one I know about.
This leads to a more specific question - how those fuels (after a bit
of processing, naturally) can be useful as a source of methanol ?

their intellectual
property rights viciously as there are different compounds that have
different properties under different conditions.
That's probably why you can't really find any information about kind of
additions at least (not proportions which are significant).

That's the problem. I haven't seen any of those specifics based on

plant-based
fuels are not so good for warming environment because of emission they
introduce anyway. It was a bit like playing with facts to avoid those
less comfortable for the speaker.
