Catching up on ancient email.
If one continues mixing until the reaction is complete and I have not
heard of any evidence that indicates separation is required for the
reaction to complete and then introduces into the reactor enough acid to
quench the sodium catalyst then I see no reason why y
and cautious enough
to create a vapor tight system.
Not so sure that everyone falls into those categories of abilities though.

Thanks, Todd, for going to the trouble of running that test.
Can I run my own tests like the one you described if I can figure out
how to make a condenser? Although I'm currently at the small batch
(two liter-sized) processing level, I would like to develop and
practice using a small condenser

Todd, is the amount of methanol remaining in the methyl ester
considered negligible? Is it possible to determine what percentage

The reaction is not exactly reversible. "Reversability" would require the
three glycerides and the glycerol recombining. That doesn't happen. Once the
glycerol is cleaved it is out of the picture.

So would I. Most of the methanol goes into the aqueous (glycerine)
layer anyway, so you can recover that portion by distilling the glyc
layer
Hello
I'm a chemical engineering student working on a biodiesel production facility
design project with my senior design group at NCSU. We are only in the initial
stages and do not have a lot of kinetic data yet, but I would think that
removing methanol would certainly be detrimental to your
Hello to all:
I have read some contributions to this group about methanol recovery
and the different options. I would like to try the recovery before
separation of bio and glycerol using a condenser that would receive
the methanol fumes after finishing the reaction. I have a processor
