Hey all,
because I am a lazy person, I thought I'd have a quick ask around rather than either doing the work myself or reading the various acid-base methods.

basically, what happens if you add too much acid to the first stage - esterification?

I have heard mention too of a base base process... anyone care to post the URL?
