when I collected it. It had the highest titration I have found so far
(4.7g/L NaOH); processed using 5 + 4.7 -> 9.7g/L NaOH (methanol process).
The result gave a very heavy/gel glycerine layer. The result that has
been standing in air has formed some gelly-like, almost clear solid
suspended in the BioD. I have just finished washing a 15L tester, and it
seems to be coming up fine.
A sample that I have left in the air for a day has formed an almost
clear gel, retaining the shape of the beaker when I tip it. It is
floating in what looks like 'normal' BioD.
However - I want to understand what this is and the possible causes, and
the ramifications of using the BioD.
Hypotheses:
---
1) High water content in the source oil - hence this stuff is a form of
soap (glop soap?)
2) Something I do not know about
If it is soap, can I hope to remove it using washing alone? Once it
starts congealing, is this washing likely to work?
I am going to do some further experiments (ie. washing) to see what
happens, but I would be grateful for the benefit of others experience
dealing with this - new experience.
This is my seventh 30L batch and the first time I have seen something
like this.
Thanks in anticipation. Can provide photos if that would help with the
diagnosis.
Cheers
Don
