I tried to make the stuff from cotton without the Nitrogen. I did the
pyrolysis and the sulfonation for half the time. I guess I was too
impatient. I tested it with WVO with 12% FFA. After treatment, the FFA
content went down to only 5%. To make sure that it wasn't the leftover
acid that was doing the job, I'm doing another run, using the same
sample I made.
Then I will try to transesterify both runs.

Best,
Chris

Yes. Hot concentrated sulphuric acid lacks appeal.
