[biofuel] Acid only reactions Was: Aleks Kac's FOOLPROOF method

2002-11-09 Thread csakima

I happen to catch this mid-thread.  I thought the NaOH was an essential part
of the biodieselic reaction (to make the methoxide).  I didn't know you
could use acid to catalyse the reaction!!  Can you??

It wasn't fudging on Aleks's part. Actually it's the original  picture, from
the original process. Last time Aleks updated it he changed the process
quite a lot. When we were going through it all prior to uploading I queried
the pics with him and he said they were okay. Later somebody wrote to me
offlist asking the same question, about #7. I asked Aleks, and he said this:

That's sorta what we're trying to find out here, but it's supposed to work.
Of course it doesn't make methoxide, it uses a completely different reaction
mechanism. According to both Aleks and US Patent 4,695,411 it can be
done with conc. H2SO4, and there are even better acids out there-K

I understood only H2SO4 would work. No?

Curtis, have a look at Aleks's page, he explains it quite well.

The acid does esterification, with some transesterification, the base 
completes the transesterification.
