Is ":-) I'd suggest you check on whether the process is watertight before you start bothering about the reactor. (It ain't!) " in reference to base catalyzed reactions or something else?
I'm sorry Andy, I don't see how it could refer to anything other than the Biox reaction, it's not ambiguous. If you'd checked the links I gave you you'd have found not only further confirmation of that but a lot more information, including some you just said you've been looking for. So why don't you just do that? Here they are again:

It's a blind alley anyway, unless you really are doing advanced stuff (more advanced than Biox). Have you made any biodiesel yet, single-stage base test batches for instance?
